1. Introduction
Tourism contributes to economic growth and development of the world economy. It represents one of the largest industries in the world [
1]. In certain geographical regions, tourism has the effect of increasing employment and it is a very important socio-economic driver [
2]. Especially in rural areas, tourism is a tool for improving these areas because agricultural activity is unstable and unpredictable [
3]. The recession in rural areas is a general global phenomenon that is the result of industrial revolution, so tourism and various other activities are becoming important for development of rural areas [
4] in order to improve these areas. As a result, the importance of the agricultural sector in rural areas is declining and increasing attention is being paid to tourism [
5].
Rural tourism activities require efforts by the local community to attract the attention of potential tourists to visit the area through event planning [
6]. To attract the attention of tourists, the rural area should possess tourist potential. If the rural area has no potential, then it is difficult to develop the tourist offer. Before the tourist offer is developed, it is necessary to research the tourist potential of a certain area.
The focus of this study is tourism rural potential of Brčko District. Within the development strategy of Brčko District, it is stated that development of Brčko District should be based on tourism, agriculture, and entrepreneurship. Brčko District is an independent administrative unit of Bosnia and Herzegovina located in the northeast of the country. Brčko District has a tradition of various forms of tourism and very good opportunities for development of rural tourism. The model for determining the rural tourist potential was developed on the example of Brčko District.
Criteria for rural tourism potential can be different in natural, cultural, historical, and socioeconomic [
7]. To assess rural tourism potential, it is necessary to apply the overall approach of evaluating the criteria of tourism potential. Due to the existence of multiple criteria, this decision problem is performed using the method of multi-criteria analysis (MCDA). MCDA is used when it is necessary to compare alternatives using certain criteria [
8]. The assessment of rural tourism potential in Brčko District was performed using a decision-making model based on the application of fuzzy logic. Fuzzy logic is applied to complex problems that cannot be easily described by traditional mathematical models. It provides a broader framework compared to classical logic and enables development of models that reflect human thinking in real problems.
To assess the rural tourism potential, it was necessary to develop a model that allows experts to assess individual alternatives based on the set criteria. Based on these assessments, the experts assessed the rural tourism potential, looked at their pros and cons and provided guidelines for improvements to the rural potential in Brčko District. The significance of this study is that an innovative research model has been created that was used to examine the rural tourism potential. In previous studies, different approaches were used to measure tourism potential, a mathematical model for evaluating criterion weights [
7], an assessment of demand for attractiveness of tourism potential [
8], estimates of tourism potential and estimates of discrimination parameters [
9], identifying key success factors, risks and tourism potential in rural and mountainous regions [
5], tourist sites for Geocaching [
10], the potential of coastal rural tourism [
2], examining the potential for tourism development in a focused economy [
11]. It can be concluded that examining rural tourism potential through a decision-making model represents a new approach in solving this problem.
The contribution of this study can be found in a new way of evaluating tourism potential using expert assessments and using fuzzy logic. The model was used to evaluate rural tourism potential and to determine the strengths and weaknesses of individual rural tourist settlements. The application of a new approach based on the principles of sustainability will enable the improvement of rural tourism, while respecting the responsible use of natural resources and the preservation and nurturing of culture and tradition in the observed areas. All this aims to strengthen rural areas through tourism development. In addition, the guidelines were provided for improving rural tourism potential in Brčko District. The obtained research results interpret the current state of rural tourism potential in Brčko District and provide the necessary information to improve the tourist offer. This research will serve the rural settlements in Brčko District to look at the current tourism offer and to improve the tourist offer by implementing the guidelines obtained in this research. The research will also support managers of certain tourism capacities to improve their business. With development of the tourism offer, it will influence the development of the entire local community.
The aims of this study are focused on:
- (1)
Create a model for measuring rural tourism potential
- (2)
Examine the current situation regarding the tourist offer
- (3)
Rank rural tourism potentials in Brčko District
- (4)
Provide guidelines for improving the tourist offer in Brčko District.

In addition, this section provides guidelines for improving rural tourism potential in Brčko District. In conclusion, the most important results, shortcomings of this study and guidelines for future research are given.
3. Research Methodology
The methodological framework for the assessment of rural tourism potentials was implemented through three phases (
Table 1).
The first phase was the research phase. At this stage, a decision was made to assess the rural tourism potential in Brčko District. The assessment of the rural tourist potential was done in cooperation with the Government of Brčko District of Bosnia and Herzegovina. According to their developmental strategy, the focus is on strengthening agriculture, economy, and tourism. Since 95% of Brčko District’s area is rural, it was necessary to assess the tourism potential of the area, to provide guidelines for improving tourism in Brčko District. Expert decision-making was used in this research. In cooperation with the Brčko District Government and their Department of Tourism, potential experts were identified. As criteria for the selection of these experts, we used their experience in the field of rural tourism, knowledge of rural areas of Brčko District and the possibility of participating in this research, due to the situation caused by the COVID-19 virus. From the total number of experts proposed by the Department of Tourism, three experts were selected to assess the rural tourism potential. The first expert (DM1) was selected in the field of rural development, the second (DM2) and the third expert (DM3) were selected in the field of tourism. All selected experts have many years of experience and have worked on several projects in the field of tourism. After the experts were selected, the criteria and alternatives to be used in this research were selected. This was done by applying panel research. First, a desk research was performed analyzing previous works to identify the criteria to be used in this study. These are the following papers: Do and Chen [
34], Zhou [
18], Zhou, et al. [
32], Mikulić, et al. [
49], Topolansky Barbe, et al. [
29], Peng and Tzeng [
37], Yan et al. [
7] and Puška et al. [
22]. Four main criteria were selected: natural resources (C1), culture (C2), social factors (C3) and economic factors (C4) (
Table 2). Each of these criteria were broken down into an equal number of sub-criteria.
Once the criteria were determined it was necessary to select the alternatives to be used in this research. A basic set of surveys was formed, including 59 rural settlements. Based on the documents available to the Department of Tourism, the number of rural settlements was first reduced to 14, and these settlements were analyzed in detail. At the end, 6 rural settlements were selected with the best predisposition to perform rural tourism. Six rural settlements form a sample in this study that represent six alternatives, namely: Gornji Zovik (A1), Ražljevo (A2), Brezovo Polje (A3), Grbavica (A4), Maoča (A5) and Bijela (A6). Based on the criteria and alternatives, a research model was formed (
Figure 2). In cooperation with the Government of Brčko District, a visit of experts to these areas was organized to determine which tourist resources these areas have at their disposal. As part of the visits, the experts conducted interviews with the local population and received additional information on the rural tourism potential of these areas.
The second phase of the research dealt with determination of the weight of the criteria and the evaluation of alternatives by experts. When the criteria and alternatives were selected, a survey questionnaire was created based on these activities. The survey questionnaire consisted of two parts. The first part of the survey questionnaire was intended to assess the weights of criteria and sub-criteria. The second part of the survey questionnaire was intended to assess alternatives. The first part of the questionnaire was filled out by the experts. First, they ranked the criteria or sub-criteria according to the importance that they perceived. Then the criterion that has the greatest significance was assigned a value of 1, while the other criteria were assigned a value up to 9, with the proviso that it is possible to give values with a decimal number. The higher the value of a particular criterion, the less important it is. The second part of the questionnaire was completed by the experts by providing linguistic values for certain alternatives ranging from very poor (VP) to very good (VG), using a seven-point scale (
Table 3). After the data were collected from the experts, an initial decision matrix was formed. The initial decision matrix was the first step in applying the MCDA method.
The third phase of the research was concerned with ranking of alternatives. Before ranking alternatives, it was necessary to determine the weights of the criteria using the FUCOM method. The reason for using the FUCOM method to determine the weight of the criteria is because this method has certain advantages over other methods used from the aspect of expert examination [
50]. The experts only needed to assign a value of 1 to the criterion that is most important in their opinion, while the other criteria are assigned a value of up to 9 depending on the importance of that criterion for experts. The greater the importance of a criterion, the closer the value for that criterion will be to 1 and vice versa. This has simplified the collection of data by experts. The steps of the FUCOM method are presented in the next subsection. Once the weights of the criteria were determined, the alternatives were ranked using the fuzzy Measurement Alternatives and Ranking according to the COmpromise Solution (MARCOS) method. The reason the fuzzy approach was applied one can be found in the fact that the values for evaluating alternatives were presented in the form of linguistic values. Therefore, it was necessary to apply the fuzzy version of the MARCOS method. The fuzzy MARCOS method is just one of several methods that could be used as the primary method in the research. The reason why the fuzzy MARCOS method was chosen, and no other methods, is that through the application so far, this method has shown that its results are concisions from other methods [
51]. However, the results given by this method are compared with the results given by other fuzzy methods, and thus the results given by this method will be confirmed or refuted. The steps of the fuzzy MARCOS method are presented in the next subsection. After the ranking of the alternatives was determined, the obtained results were examined. The results obtained using the fuzzy MARCOS method were first compared with other selected methods, and then the sensitivity of the ranking of alternatives to changes in the weight of the criteria was performed.
3.1. FUCOM (FUll COnsistency Method) Method
The FUCOM method was developed by Pamučar, et al. [
50]. The FUCOM method is used to determine the weight of the criteria. The FUCOM method compares established criteria in pairs and performs the validation of results by deviating from the maximum consistency [
51]. Using this method subjectivity in the decision-making process is reduced [
52]. This method, in relation to other methods for determining the subjective weights of criteria, has the main advantages: reduced number of pairs to compare, consistency in comparing criteria and contributing to rational judgment [
53].
The FUCOM method is implemented using the following steps [
50]:
- Step 1.
Ranking of criteria/sub-criteria using expert evaluation.
- Step 2.
Determining the vector of comparative significance of the evaluation criteria.
- Step 3.
Defining the constraints of a nonlinear optimization model. The values of the weighting coefficients should satisfy two conditions, namely [
54]:
- -
Condition 1. The ratio of weight coefficients is equal to the comparative significance between the observed, the condition is met when:
- -
Condition 2. The final values of the weighted coefficients should satisfy the condition of mathematical transitivity, i.e.,
- Step 4.
Defining a model for determining the final values of the weighting coefficients of the criteria [
55].
- Step 5.
Solving the model and obtaining the final weight of the criteria/sub-criteria
3.2. Fuzzy Measurement of Alternatives and Ranking According to COmpromise Solution (MARCOS) Method
The MARCOS method was developed by the authors Stević, et al. [
56]. The MARCOS method uses a defined relationship between alternatives and the reference values of those alternatives that represent ideal and anti-ideal solutions. Determining the final order using the MARCOS method is done based on the utility function [
57]. The value of the utility function of the alternative is obtained in relation to the ideal and anti-ideal solution. The best alternative is the one that is closest to the ideal solution and at the same time the furthest from the anti-ideal solution [
53]. The Fuzzy MARCOS method consists of the following steps [
58]:
- Step 1.
Forming an initial fuzzy decision matrix.
- Step 2.
Extension of the initial fuzzy decision matrix. In this step, the initial matrix is expanded with the anti-ideal (AAI) and ideal solution (AI). The anti-ideal solution (AAI) is obtained by applying the following expression:
The ideal solution (AI) is obtained using the following expression:
where B represents benefit criteria that need to be maximized, while C represents cost criteria that need to be minimized [
59].
- Step 3.
Normalizing the initial fuzzy decision matrix. Normalization is performed using the following expressions depending on the criterion in question:
where
l is the first fuzzy number,
m is the second fuzzy number and
u is the third fuzzy number.
- Step 4.
Aggravation normalized decision matrix. The aggravation of the normalized decision matrix is done using the following expression:
- Step 5.
The calculation of Si matrix implies the sum of the values by the alternatives including the anti-ideal and ideal solution by the following expression:
- Step 6.
Calculation of the degree of usefulness of Ki in relation to the anti-ideal and ideal solution using the following expression:
- Step 7.
Calculation of the fuzzy matrix
using the following expression:
Determining the fuzzy number
using the following expression:
- Step 8.
De-fuzzify of fuzzy numbers using the following expression:
- Step 9.
Determining the utility function through the aggregation of utility functions according to the anti-ideal solution (a) and the ideal solution (b).
Utility function according to the anti-ideal solution
Utility function according to the ideal solution
- Step 10.
Calculation of the final utility function:
- Step 11.
Ranking alternatives. The best alternative is the one with the highest value, while the worst is the alternative with the lowest value.
4. Results
Before evaluating the alternatives used in the research, the weights of the criteria were determined. The weights of the criteria and sub-criteria were performed by filling in the first part of the survey questionnaire by experts. The experts first determined the weights for the main criteria and then for the sub-criteria. When evaluating the main criteria, experts 2 and 3 gave the greatest importance to criterion C1, while expert 1 gave the greatest importance to criterion C3. Other criteria were ranked, and their values determined (
Table 4).
By applying the steps of the FUCOM method, weights were obtained based on the evaluation of individual experts (
Table 5). By applying the arithmetic mean, the final weights of the criteria were obtained. Criterion C1 is of the greatest importance for experts, followed by criterion C3 and criterion C4. Based on the obtained results of the weight of the main criteria, it can be concluded that criteria C1 and C3 have similar importance while criteria C2 and C4 have less importance compared to the first two criteria.
After determining the weights of the criteria, the experts determined the weights of the sub-criteria in the same way. They first determined which sub-criterion is the most important in their opinion and ranked the other criteria according to importance. Then, they determined the vector of comparative significance of these sub-criteria. Using the steps of the FUCOM method, the weights of all the criteria for each expert were established and the final weights were determined using the arithmetic mean (
Table 6). Sub-criterion C12 has the greatest importance in criterion C1, sub-criterion C21 has the greatest importance in criterion C2, sub-criterion C34 has the greatest importance in criterion C3, while sub-criterion C43 has the greatest importance in criterion C4.
After determining the importance of certain criteria and sub-criteria, the experts evaluated the rural settlements in Brčko District that were taken as alternatives. Experts assessed rural settlements using linguistic values (
Table 7). Since the estimates of rural settlements are given in the form of linguistic values, it was necessary to transform them into numerical values using the affiliation function (
Table 4). After this step, the experts’ assessments were harmonized by applying the arithmetic mean. In this way, a collective decision matrix was formed, which is the first step in the implementation of MCDA methods. The second step in applying the fuzzy MARCOS method was to expand the initial decision matrix with ideal and anti-ideal solutions (expressions 1 and 2). The third step was to normalize the initial decision matrix. Since all criteria and sub-criteria are of the benefit type, expression 3 was used. The fourth step of the fuzzy MARCOS method was to make the normalized extended decision matrix difficult. In this step, the values of the normalized decision matrix were multiplied by the corresponding weights.
The fifth step was to calculate the S
i matrix to determine the sums of values of the alternatives including the ideal and anti-ideal solution (
Table 8). Based on the S
i matrix, the utility levels were calculated, which was the step 6 in the fuzzy decision matrix. These degrees of utility were calculated in relation to the anti-ideal and ideal solution. The seventh step of the fuzzy MARCOS method was to calculate the fuzzy matrix
. This was done by adding the appropriate members of the fuzzy numbers with the degree of usefulness and in relation to the anti-ideal and ideal solution.
To determine the utility function, it was necessary to identify the value of
dfcrisp in the step 8. This value was obtained by determining the maximum values of the fuzzy matrix
and by de-fuzzify these maximum values. In step 9, the utility function was calculated by relating the utility function to the
dfcrisp value (
Table 9). After this step, the utility level and the utility function are de-fuzzify to calculate the final utility function.
The step 10 in the fuzzy MARCOS method was to determine the final utility function that was the basis for ranking alternatives. The values obtained by the final utility function represent the final value obtained using the fuzzy MARCOS method (
Table 10). The step 11 was applied by ranking the alternatives based on the final utility function.
The results obtained using a combination of FUCOM and fuzzy MARCOS methods and based on expert decision-making have shown that the best rated alternative is A6, followed by alternative A3, while the worst rated alternative is A4. To confirm these results, they were tested.
5. Examination of Results and Discussion
5.1. Examination of Results
The results were examined within two steps. The first step was focused to examine how other fuzzy methods rank alternatives and whether this ranking order differs from the ranking order obtained using the fuzzy MARCOS method. The second step was to examine how a change in the weight of the sub-criteria affects the ranking of the alternatives.
The first step of testing the research results was performed using five other fuzzy methods: fuzzy Weighted Aggregated Sum Product Assessment (WASPAS), fuzzy Simple Additive Weighting (SAW) technique, fuzzy Multi-Attributive Border Approximation area Comparison (MABAC), fuzzy Additive Ratio Assessment (ARAS) and fuzzy Technique for Order Performance by Similarity to Ideal Solution (TOPSIS). The results obtained (
Figure 3) have shown that the results differ within the fuzzy TOPSIS method, where alternatives A1 and A5 replaced the ranking order. Other alternatives have kept the same ranking. Thus, it has been proven that the ranking order obtained by the fuzzy MARCOS method does not differ from the ranking order obtained by applying other fuzzy methods.
The second step was aimed on sensitivity analysis. In the sensitivity analysis, the results of the research were examined by changing the weights of the sub-criteria and determining how these weights affect the results [
60]. Since there are 16 sub-criteria, 17 scenarios were formed (
Table 11). The first 16 scenarios gave preference to one of the sub-criteria and this sub-criterion was assigned a weight of 0.25, while the other criteria were assigned a weight of 0.05. Thus, this criterion was given a five times advantage over other sub-criteria. In 17 scenarios, all sub-criteria are assigned the same weight (w = 0.0625). The results of these scenarios are presented in
Figure 4, where the scenarios are presented on the x-axis, while the ranked alternative for certain scenarios are presented on the y-axis of the figure.
The results of the sensitivity analysis have shown that alternative A6 is insensitive to changes in the weights of the sub-criteria and in all scenarios retained first place in the ranking. Alternative A3 was second in the ranking in 16 scenarios, only in scenario 11 it took the third place in the ranking. Alternative A2 achieved 3rd place in the ranking in 11 scenarios, took 4th place in the ranking in 4 scenarios, while it took 5th place in the ranking in 2 scenarios. Alternative A5 took 4th place in 10 scenarios, took second place in one scenario, took third place in 2 scenarios, ranked 5th in three scenarios, and took last place in ranking in scenario 16. Alternative A1 took the fifth place in the ranking of alternatives in 8 scenarios, and took the 3rd, 4th, and 6th place in the ranking of alternatives in three scenarios. In this way, alternatives A5 and A1 have shown the greatest sensitivity to changing the weights of the sub-criteria. Alternative A4 took the last place in the ranking in 13 scenarios, while in 4 scenarios it took the 5th place in the ranking of alternatives. In this way, alternative A4 have shown that it has the worst rural tourist potential of the observed rural settlements in Brčko District, while alternative A6 have shown that it has the best rural tourist potential of all observed rural settlements.
5.2. Examination of Results
This study has introduced the model for determining rural tourism potential using a combination of two MCDA methods, namely FUCOM and fuzzy MARCOS. The results of this decision-making model have shown that the rural settlement of Bijela has the best tourist potential, while the rural settlement of Grbavica has the worst tourist potential among observed settlements based on expert assessments. The assessment of tourism potential was performed based on 4 main criteria and 16 additional criteria. In determining the rural tourism potential, we adjusted the main criteria given by Yan, et al. [
7]: natural criteria, culture, social resources, and economic resources. In contrast to this research, cultural and historical potential are combined in this study, while social and economic potentials are separated. The reason for that is due to the specificity of the observed areas.
The area of Bosnia and Herzegovina can boast of natural, cultural, and historical potential, while social and economic resources need to be improved, as shown by expert assessments. Due to the recession present in rural areas [
4] and the outflow of population, the decisive factors for the development of tourism in Bosnia and Herzegovina are social resources as well as natural resources available to these areas. In addition, cultural and natural resources are key factors in promoting sustainable development of tourist areas [
61]. Based on this, it is necessary to assess rural tourism potential as a multidisciplinary concept and it is necessary to include all factors that may affect the development of tourism.
Economic resources can be influenced and improved through investments in infrastructure, while natural resources and tradition cannot be influenced. Therefore, it is necessary to invest in economic resources through development policies, investments, and coordination of activities [
28] to improve the tourism potential of rural settlements in Brčko District. It is necessary to invest in hotels and other tourism facilities [
25]. By investing in economic resources, it is possible to improve the conditions prevailing in rural settlements. If the population is provided with better living conditions and a better standard of living, they will remain to live in rural areas. This can improve social resources and improve rural tourism potential.
From the obtained results, Bijela has the best rural tourist potential, while Grbavica has the worst among those observed settlements. To improve rural tourism potential of Brčko District, it is necessary to consider all individual criteria and determine which criteria should be improved by one of the rural settlements to improve these capacities.
Gornji Zovik possesses tourism potential through natural resources and culture, while the shortcomings are social and economic resources. This area has rich natural resources, cultural events are also organized on a regular basis, and this settlement has a lot of historical buildings. Gornji Zovik needs to invest in tourism through development policy and improve the missing economic resources that need to be built. The settlement of Ražljevo has poor social resources, while its economic resources are the best among observed. Ražljevo needs to use more effectively natural and cultural resources that are at disposal. The settlement of Brezovo Polje has the best indicators in terms of culture, but it has the worst social resources. Grbavica has equally distributed all resources that are not well developed. In this settlement, investment must be done in all resources to improve their tourism potential. The settlement of Maoča, as with other settlements, has low levels of human resources, while other resources are well developed, but more investments must be made in this area to improve their tourism potential. The rural settlement of Bijela has good cultural and historical potential, while there is still more work to be done on social resources.
Based on the previous findings, it can be determined that social potential is missing within all rural settlements. The Brčko District Government must invest in raising people’s awareness of tourism. It is necessary to educate people to use the tourism potentials that this territory has at their disposal. It is also necessary to change the political environment to invest more in development of rural areas, where tourism should be one of the basic activities.
This study has shown that the rural tourism potential of Brčko District can be determined using a created model based on MCDA methods. This model has shown what are the real tourism potentials in the observed rural settlements. These results can direct the activities towards the improvement of rural tourism potential in Brčko District. It is also possible through certain modifications to use this model in other branches of tourism and thus get a global picture of the tourism potential of Bosnia and Herzegovina and other countries.
6. Sustainability Rural Tourism, Emotions, COVID-19 and Values: Future Research
Numerous researchers [
62,
63,
64,
65,
66,
67] paid a good deal of attention to emotions in their studies on sustainable tourism and rural tourism. “Three Fs” is the name coined by Holbrook [
62] for an experiential approach. This approach focuses on fantasies including dreams, imagination and unconscious desires; feelings involving emotions like love, hate, anger, fear, joy and sorrow and fun consisting of hedonic pleasure coming from playful activities or aesthetic enjoyment. Hence the “three Fs”, fantasies, feelings and fun, comprise the key aspects of an experience in consumerism. There is a certain way in which Holbrook [
62] analyses social, hedonic and altruistic values. His versions are briefly presented. Social value involves a person’s wanting to form the responses of other people by that person’s own behaviour when consuming goods and services. Hedonic value is simply the pleasure a person experiences when consuming, constituting the means and the end in itself. Meanwhile
fun is the output coming from engaging in leisurely pastimes that are different for different individuals like sports for some or playing music for others. There is
aesthetic enjoyment that comes from something a person beholds, whether it be artistic works, recreation or natural, outdoor beauty. Additionally
altruistic value derives from self-justifying endeavours involving awareness of how one’s own consumption affects matters, which are often viewed as an end-in-itself like charitable donations. These can be said to be “goodness for the sake of goodness”, which is an
ethically desirable practice [
62]. Other scholars like Chen et al. [
63] have investigated “fun” emotions reported by tourists about their memorable experiences and the relationships thereof including pertinent recommendations. The “fun” emotion, i.e., a certain emotional spark and flow, had been positively influenced by hedonism, novelty, meaningfulness, and social interactions, as reported by Chinese tourists travelling abroad. It is no surprise that these same Chinese tourists tended to recommend their destinations to others as well as to revisit them after experiencing an intense “fun” emotion [
63]. An extended model of goal-directed behaviour was applied by Bui and Kiatkawsin [
64] for their research regarding Vietnamese hard-adventure tourists. They concluded that marketing needs to focus on information and building a favourable attitude, because they discovered that the direct impact on a visiting intention by robust tourists were, first and foremost, an attitude and an anticipated positive emotion. These were the two most important factors. Nonetheless, the confidence of such tourists require bolstering by information regarding tour routes, available protective equipment, relevant insurance policies and such [
64]. This study by Bui and Kiatkawsin [
64] concluded that a favourable attitude forms as a result of providing illustrations about how participation potentially fosters emotional responses. Low-carbon service operations constituted the focus of the research by Chang et al. [
65] who looked into sustainable cultural tourism and explored the impact on it by responsible tourist behaviour. The two important elements for sustainable island tourism that outcropped by conducting primary and secondary data analysis were the supply and a demand side of a destination. Low-carbon service operations constitute the supply side, involving the regular food and lodging services but adding ecological tourist activities. Meanwhile the behaviours of those buyers of tourism reflect the demand side. Cognition, emotion and motivation along with their authenticity express such demand [
65]. Happiness or sadness, e.g., reference a reaction to an incorporation of personal feelings, i.e., an emotion. Individual experiences of reality are what emotions represent [
66]. For example, backpacking tourists require sustainable travel in a natural environment. Walking, riding bicycles or trains, driving, camping out—these all result in feeling “enjoyment” or “happiness”; however only for some. Others would view all those mentioned recreational activities as hardships [
65]. The ethical choices consumers make often rely on emotions, as Malone et al. [
67] examined. These scholars focused on ethical tourism as they examined the relationship between pleasure and ethical tourism consumption due to hedonic values. Emotions play their roles in ethical tourism, according to the experiences reported by numerous tourists, along with the sorts of hedonic values they experienced in their interactions. This bolsters the idea about the key roles played by emotions when it comes to influencing and motivating ethical choices. Furthermore this also forms the experiences buyers derived by consuming ethical tourism [
67].
Scholars and practitioners [
68,
69,
70,
71] discussed the impact COVID-19 was having on tourism by directing much attention to the subject of emotions and the play of their related values. The hospitality industry, for one, has faced unprecedented challenges in the face of the current pandemic. Hospitality businesses were forced to shut down, albeit this presumably being temporary, due to most or all measures taken to flatten the curve on COVID-19 cases like community lockdowns, social distancing, stay-at-home orders and other restrictions on travel and mobility. The resulting closure of many business operations significantly decreased demand, thereby decreasing operations even more and diminishing chances for ultimate survival [
68]. Time and surrounding conditions cause changes in consumer behaviours. The differences produced depend on the hedonic and utilitarian values that had effectively aroused purchasing behaviours. For example, the current COVID-19 pandemic has been responsible for a shift in consumption behaviours. People express their values and behaviours differently under conditions of insecurity when life itself is being threatened [
69]. A finding by Ozturk [
69] indicates that, under high-risk conditions like the COVID-19 pandemic or other such situations, people tend to purchase food for their hedonic or utilitarian value, something that positively affects online shopping. Another study by Ahn and Kwon [
70] analysed economic, hedonic, social and altruistic values in their discussion regarding integrated resort destinations in Malaysia. Green practices may have attracted significant interest by the tourism and hospitality industry recently; however, studies on the factors contributing to positive behaviours by consumers have been lacking. Hence the Ahn and Kwon [
70] study focuses on the attitudinal loyalty tourists may feel for a green hotel. The cognitive–affective–conative framework can explicitly serve as the basis for a model studying how cognitive evaluation involving perceived cost and value, affective responses involving positive/negative anticipated emotions and attitudes as well as a conative sense involving behavioural intentions link together. Apparently, according to the findings, consumers’ perceived values have expressed both positive and negative emotions relevant to received benefits. These results reveal the importance of prior experiences in forming the attitudes of consumers regarding their intended behaviours pertinent to different brand names of green hotels. A research gap has been filled by this study by Ahn and Kwon [
71] about how attitudinal loyalty forms among consumers and its mechanisms regarding green hotels. Meanwhile a strategy of rehousing individuals led to less homelessness in society due to social value co-creation, as per Ratten [
72]. Social welfare policy makers targeted hotels and apartment units previously serving tourist needs to house homeless people in the wake of the societal effects caused by COVID-19. Previously this had not been possible, since housing accommodations had involved solely profit generating activities [
72]. Other research findings involved consumer views regarding sit-down restaurants. Apparently some 25% of reviewed consumers reported they would only feel comfortable about eating out when there is a significant improvement in testing, tracing and isolating COVID-19 cases. Then, some 18% of reviewed consumers reported only feeling comfortable visiting destinations or hotels when the area had very few COVID-19 cases coupled with an ability to test, trace and isolate COVID-19 cases. Additionally some 14% of potential consumers reported discomfort about going to a sit-down restaurant and some 17% about traveling and staying at a hotel before the availability of a COVID-19 vaccine appears [
73]. Making matters worse, travel and tourism services require upholding social distancing regulations due to COVID-19. Services had to be provided devoid of any close interactions between customers and employees to safeguard from COVID-19 infections. Thus the most appropriate substitutes proved to be AI service devices to permit implementation of social distancing regulations and thereby decrease needed interactions with human employees [
74].
The above two paragraphs pave the way for further research regarding the integration of the multi-attribute market value assessment (MAMVA) [
75,
76] approach and others for further development. Thereby a new technique might be developed for investigating the potential of sustainable rural tourism pertinent to quantitative and qualitative indicators for alternative selections. The potential of sustainable rural tourism could then be examined by comparing the best-performing alternative, as per such a new technique, to determine an alternative’s efficiency and utility degree. Values defining the potential efficiency of sustainable rural tourism can vary from 0% to 100% when applying MAMVA. A visual assessment of the potential efficiency of sustainable rural tourism thus becomes realistic. The potential efficiency of sustainable rural tourism along with the pertinent market, hedonic and customer-perceived values become directly proportional to a system consisting of adequate indicators that includes the indicator weights and values. Consequently the results of this research in combination with neuro decision matrices [
77,
78] and MAMVA method [
75,
76] can serve as the basis for determining the market, hedonic and customer-perceived values of the potential of sustainable rural tourism.
To apply all this, it is necessary to introduce innovation in rural tourism. Innovation helps to exploit tourism potentials in creating an attractive tourism product. Cetin et al. [
79] suggested that nature should be protected in certain rural areas. This nature protection will strengthen the sustainability and design of the landscape and provide the development of tourist activities. Roman et al. [
80] said that innovation in tourism should help create an original tourism product and provide a professional marketing mix for the natural and cultural assets of a particular area. The application of innovation in tourism will enable the use of tourism potentials and improve tourism in these areas [
81]. However, the application of innovation in tourism requires planning activities and development of adequate policies to apply innovation in tourism in a particular area [
82]. By encouraging innovation in tourism, it is possible to improve a country’s competitiveness [
83].
The determination of a system, its values, the decision criteria weights, validation of the developed evaluation approach and other factors are involved in a decision making process that, in and of itself, depends highly on experts. The potential of incorporating neuro decision-making and neuro-questionnaires are possible for use in future research, which could improve the decision-making process. Thus this multifaceted decision process then offers interested parties an opportunity for more effective and reliable interpretations.
7. Conclusions
Tourism potential is the first step in carrying out tourism activities. It is necessary to determine the tourist potential of certain areas and build a tourist offer based on this potential. Without the tourist potential of a certain settlement, it is difficult to develop tourism in that area. The Brčko District Government is focused on development of the economy, tourism, and agriculture in different strategies. The development of tourism in Brčko District needs to be implemented in all areas. Since most of the territory of Brčko District is a rural area, it is necessary to develop tourism in these areas. This study was conducted in cooperation with the Brčko District Government. The aim was to explore the rural tourism potential of Brčko District. To achieve this goal, an expert assessment of rural tourism potential of Brčko District was used. In cooperation with the Department of Tourism of the Government of Brčko District, experts were selected, and a model was created to examine rural tourism potential. Six rural settlements were selected together with experts. The results showed that the observed rural settlements have good tourism potential. The best results were shown by the rural settlement of Bijela, while the worst results among selected in terms of tourist potential were shown by the settlement of Grbavica. To improve the tourist potential, it is necessary to improve social and economic resources in these areas. The Brčko District Government needs to improve the conditions prevailing in these rural settlements to develop tourism.
The disadvantage of this study is that not all rural areas in the territory of Brčko District were taken into analysis. However, those settlements that currently have good tourism potential were taken. When tourism in Brčko District is further developed, this will affect the tourism potential of other rural settlements to be improved. Thus, it is necessary to include these rural settlements in future research. Furthermore, the limitation of this study is that only three experts who assessed the rural tourism potential in Brcko District participated, especially because the opinion of the first expert differed from the others in terms of the importance of the criteria. The primary reason why the opinions of these experts were taken is the inability of more experts to participate due to the pandemic caused by the COVID-19 virus and the inability of more experts to participate. In future research of rural potentials of the Brčko District, it is necessary to include more experts to consider the different opinions of experts, which was partially considered in this study in terms of determining the importance of criteria and sub-criteria.
The conducted research provided a good basis for development of models for testing not only rural but also other types of tourism. The analysis of examination of results showed that the results given by the fuzzy MARCOS method do not differ from other fuzzy methods, so this method can be used in future research without restrictions. When determining the weight of criteria and sub-criteria, it is necessary to conduct research and determine which of the methods is the easiest to apply and at the same time gives reliable results to improve the implemented methodology with some other methods. In the following studies, the model needs to be improved so that it can be used in all branches of tourism. Several criteria need to be included to identify key resources for determining tourism potential. Based on that, new models could be created for determining tourist potential and other forms of tourism. The conducted research and applied methodology provide a good basis for examining tourism potential. Based on the results of this research, the necessary information is obtained on how to improve the rural tourism potentials in Brčko District.
