An Assessment of Food Value Chains to Identify Gaps and Make Recommendations for Further Development: A Slovenian Case Study
Abstract
:1. Introduction
2. Materials and Methods
2.1. Context Analysis of Added Value in Food Supply Chains
- -
- Trust between the stakeholders (producers, processors, traders, and consumers) along the agri-food chains;
- -
- The price of the end product evenly distributed among all participants (with slight variations depending on the costs in the process);
- -
- Increased market orientation in terms of supplying locally produced food and increasing demand for it.
- -
- Through agricultural products or foods made from raw materials, which demonstrate the origin of the food and thus the added value and consequently a higher price on the market;
- -
- Through protected food names that express either the geographical location, the higher quality of the raw materials and/or food safety;
- -
- As a network of proper business relationships and interactions between the different actors in the food chain.
- -
- In the following, Stevenson and Pirog [33], Pirog and Bregendahl [34], and Stevenson et al. [35] have developed a definition that defines agri-food chains with added value. The definition is mainly based on a description of the differences between chains that do not express added value and those that do. One can speak of value-added agri-food chains if the following important principles are taken into account and differ from conventional agri-food chains in these segments:
- -
- The business relationships between the strategic partners in the chain are based on common principles that are primarily based on trust. In the chain, one of the strategic partners stands out and makes a major contribution to the good and organised functioning of the chain.
- -
- In the chain, the growers/farmers are treated equally as strategic partners with all rights and obligations in terms of risk-taking, management, and decision-making.
- -
- The obligations and rights in the chain apply equally to all participants in the chain.
- -
- The coordination of the actors in the chain is effectively coordinated at the local, regional, national, and/or international levels.
2.2. Research Methodology
- Collecting statistical data and recalculating the data according to the methodology of each indicator
- Analysis and assessment of case studies using the DEXi model based on defined criteria or constraints
- Plus-minus-1 analysis of the case studies based on the boundaries of the DEXi model
2.3. Model Development Theory
- -
- DEX uses qualitative discrete criteria; values are usually described in words (qualitative values), rarely in numbers or numerical intervals;
- -
- Utility functions are defined by simple decision rules of the type “if—then”.
- Knowledge acquisition and preparation: it helps the user to create a tree of criteria and decision rules for the problem under consideration; it is a process of structuring a decision problem and expressing preferences, where the consistency of the given decision rules is also checked by the computer on the fly.
- Evaluating and analysing variants: The acquired knowledge base is used to evaluate and analyse variants.
- -
- Explanations of the assessment: DEXi is able to explain how each individual assessment was arrived at based on the criteria values and the decision rules used.
- -
- “What-if” analysis: it is performed interactively by changing the description of the variants, re-evaluating them and comparing the results obtained with the original (reference) results.
- -
- Selective interpretation of variants: DEXi finds and outputs the sub-criteria trees that reflect the strongest or weakest features of each variant, extracting only the most relevant information.

Change in the ratio between retail price and own price | Average year-on-year change in the ratio between the average retail price of agricultural products and the own price, on an annual basis, in % Z = average year-on-year change in ratio X (ratio) = retail price/own price Y (year-on-year change in ratio) = ((X – X–1)/X–1) × 100 Z = (Y1 + Y2 + … + Yn)/n | Added value or a positive economic situation for the primary producer (farmer) occurs if the prices of inputs rise more slowly than the prices of agricultural products for growers.
