Modeling a Logistics Hub Using the Digital Footprint Method—The Implication for Open Innovation Engineering

: Optimizing the cargo ﬂows through the nodes of a digital transport corridor is a crucial problem; solving it allows to introduce modern management methods in logistics. This study ex-amines the optimization of the technology of a distribution center as the base node of a third-party logistics network operator. Our objective consisted in theoretically substantiating the application of mathematical formalisms to describing the passage of stochastic goods ﬂows of a complex structure through a node of a logistics network. To solve the problem, we constructed a mathematical model intended as a decision-making block in the Warehouse Management System software. This paper presents the results of calculations carried out using a computer according to the proposed algorithm. Preliminary results allow to conclude that there is a signiﬁcant resource for reducing construction and maintenance costs of the distribution center. Quantitatively, the savings will range from 10% to 40%, depending on the terms of delivery of goods and the degree of market uncertainty. An example of a practical calculation using the developed mathematical model is given. The calculations were performed for Huawei, a key global provider of ICT infrastructure and smart terminals. The algorithms were designed to account for uncertainty, which allows to use the results for risk management applications. In practice, this theoretical concept can serve as a basis for digital logistics platforms, increasing the speed of delivery of goods and cargo and the proﬁtability of logistics as a result. The solution to this problem will allow to consider the nodes of logistics networks as smart independent divisions with an information interface for interaction built into a digital logistics platform. The role of these nodes is to make the best decisions in handling cargo ﬂows. As the next stage of research, we plan to develop algorithms for coordinating the information ﬂows reﬂecting transport activities and forming the material ﬂows entering and leaving the distribution centers.


Introduction
The modern trend for the development of digital transport corridors makes it possible to put into practice the advantages of machine-to-machine communication technologies and intelligent systems for making management decisions. The basic concepts underlying the research could be considered as follows. Firstly, it is possible to create a transnational logistics network in numerous nodes of which manufacturers, suppliers, transfer points, distribution centers are located. Secondly, when forming a common logistic space for business, it becomes necessary to solve a number of problems, since any commercial activity takes place in conditions of uncertainty [1,2]. The load on logistics also depends on the volume of demand, market situation, seasonal factors and traffic restrictions, on which the range of the spent time depends. If the technical basis for the exchange of information [3] in real time is already available, then the problem of optimizing logistics flows is still being solved fragmentarily. For this purpose, ERP (Enterprise Resource Planning), Customer Relationship Management), SCM (Supply Chain Management), EWM Consulting Solutions and WMS (Warehouse Management System) systems are used [4,5]. The purpose of this study is to develop an algorithmic basis for managing distribution centers. Such logistics hubs are distributed all over the world as the basis of the 3PL (Third Party logistics) logistics outsourcing complex [6]. The efficiency of their work determines such parameters as the time spent on the delivery of goods and cargo, maintaining the necessary stocks, storage costs, including those caused not only by overstocking but also by possible costs for late delivery [7]. To this must be added the limited expire date characteristic of FMCG (fast moving consumer goods) which occupy the maximum share in the total mass of transported goods. To solve this problem, this paper analyzes the current state of research in the field of commercial logistics networks [8], defines the methodological foundations, formulates the problem statement and basic formalisms and applies the method of mathematical modeling. To illustrate the results, a study was carried out on Huawei data and a numerical calculation using a computer is presented. The proposed structure of the paper includes 5 sections: 1. Introduction discloses the purpose of the research and the basic concepts; 2. The theoretical Foundations include both literature review and problem statement as well as the method of the research and mathematical modelling; 3. The result section presents the obtained findings being explained in seven subsections; 4. Discussion section reveals the both the research from the point of view of open innovation concept and the topic for future research; 5. Conclusion presents the contribution of the research in the beginning of the sections and in three subsections.

Literature Review
The research is considered on the basis of the fundamental theory being developed by JinHyo Joseph Yun who suggested the open innovation engineering model, including both open-innovation engineering channels and determining ways of operating the channels through conceptual experiments [9]. The authors find very useful the effects of the mechanism design (fundamental to the study of incentives and information [10]) being expanded and implemented for developing new business model from open innovation and Schumpeterian new combinations [11,12] as well as open innovation based business model design compass [13]. Undoubtedly, the implementation of innovative activities is associated with the implementation of innovative models. It is very interesting that the Christensen's determinants of open innovation model associated with the industrial dynamics of an industry segment undergoing a process of radical technological innovation [14] unraveling the Chesbrough's Open Innovation concept which was initially studied by from the company-level perspective (in contrary to the closed innovation old model).
It is customary to represent a commercial network in the form of a directed graph, where the corresponding divisions are located at the nodes. Their activities are related to information [15] and material flows [16]. Analysis of the structure of 3PL providers shows that the optimal solution for the nodes of such a network is, in addition to producers and consumers [17,18], widespread introduction of distribution centers (DC) [19,20]. The role of distribution centers when they are located in nodes is to smooth out flows, as well as to reduce the cost of consumers' own storage capacity. This makes it possible to implement the concept of JIT Just In Time (J.I.T.) management in practice [21]. First of all, wholesale trading enterprises benefit from this, since their emergent stocks and, consequently, expensive SW (store warehouse) can be minimized. The volume of funds frozen in warehouses of enterprises is also decreasing [22]. In addition, manufacturers also benefit, since the JIT technology can be implemented in both directions of flows. Accordingly, new cross-docking and pick-by-line technologies are being introduced at DC [23]. The criteria for economic efficiency [24] when maximizing the 3PL operator's profit can be the minimization of costs for the DC scale and the balance between possible costs (for example, for the factors of demurrage and detention or for contractual penalties for non-delivery or late shipment) [25].
The specific strategy chosen for handling cargo and, accordingly, scientifically grounded control algorithms serves as an ideological platform for modeling; respectively, the business model is the same platform for designing and planning business processes [26,27]. The main requirement for building business processes is formulated strictly and concisely: to create value for consumers and exclude any unnecessary or obviously needless activitiesit applies to each individual business process and to all of their organizational set of processes that form a particular business [28][29][30][31][32].

Problem Statement
It is necessary to find an economically optimal management of the flows of goods and cargo based on digital information about their movement, taking into account the stochastic nature of the volumes and directions of flows. At the same time, it is necessary to choose and justify the methodology for calculating the node DC terminals included in the network structure of logistics activities. The obtained set of mathematical relations allows us to simulate the operation of a network distribution center as a node element of a logistics system that functions on the principles of 3PL operator in conditions of stochastic nature of incoming and shipped goods flows. Different project options were considered in the context of digitalization in [33][34][35][36][37].

Method of Research
The solution to the problems under consideration typically relies on the world experience in organizing network logistics. Open innovation is an emerging concept describing how companies use external ideas as well as internal ideas and internal and external paths to market, as these companies look to advance their technology. Christensen et al. [14] address how the open innovation concept can be analyzed from an industrial dynamics perspective, considering the specific measures that different companies take to manage open innovation from the standpoint of their differential position within the innovation system in question, the nature and stage of maturity of the technological regime and the particular value proposition pursued by companies. The complexity of knowledge could be investigated using the Quadruple Helix model [38] which differs from the fundamental Triple Helix model of innovation by adding a fourth helix as the "media-based and culture-based public" to the "university-industry-government relations" (three helices developed by Etzkowitz and Leydesdorff [39]) generating a national innovation systemacademia/universities, industry and state/government. Leydesdorff explains that the metaphor of a Triple Helix could be considered as a basis for making the extensions the model to more than three helices [40]. The abovementioned Quadruple Helix and suggested later the Quintuple Helix being ecologically sensitive [41] could be treated as universal and in a wide sense be extended to N-Tuple Helix model [42]. A concept model of open innovation built up in [9] is intended for exploring the existing open innovation channels, which can be useful to motivate engineering research increasing the development of open innovation and new open business models. A formalized representation of the movement of goods and cargo that reflects real market conditions, including uncertainty factors. Stochastic modeling methods from the theory of random processes are used for the description. To develop optimal solutions, the criterion of minimizing total costs is applied. The choice of performance indicators is based on the balance of logistics and storage costs, demurrage and detention with the maximum profit from logistics activities. Calculations are performed using numerical methods of the mathematical theory of optimal processes computer simulation.

Mathematical Modeling of Goods and Cargo Flows
Since in the modern organization of the processes of moving goods and cargo at each stage there is a digital footprint, it becomes possible to apply optimization algorithms for the control programs of logistics servers. To describe flows in DC nodes, we use stochastic modeling methods. We introduce the following notation-the range of incoming cargo is equal to n. Flows are described by the law of distribution with probability density λ i , where i = 1, 2, . . . , n. Then the distribution density is g (n) (t) amounts to n threads by time t entrances T 1 , T 2 , . . ., calculated using the formula Accordingly, we calculate the distribution function as: For modeling, we use the characteristics of the Erlang n-th order T (n) : Since we are interested in DC operation in cross-docking and pick-by-line modes, these characteristics are not enough. If we present the flow plot for these modes on the graph (Figure 1), it is clear that with the same mathematical expectation and variance, the nature of the processes is very different. use stochastic modeling methods.

Then the distribution density is ( ) ( ) n g t amounts to n threads by time t entrances 1 2 , ,... T T , calculated using the formula Accordingly, we calculate the distribution function as: For modeling, we use the characteristics of the Erlang n-th order ( ) n T : Since we are interested in DC operation in cross-docking and pick-by-line modes, these characteristics are not enough. If we present the flow plot for these modes on the graph (Figure 1), it is clear that with the same mathematical expectation and variance, the nature of the processes is very different. For a formalized mathematical description of the processes of movement of goods, it is necessary to additionally know the correlation functions ( , ) K t t′ . The reason for this is that the pick-by-line technology is more complex. On the one hand, pick-by-line technology provides a significant competitive advantage but requires coordination between the logistics operator, supplier and consumer. First of all, this technology is used in the network retail segment. It is the introduction of digital inter-machine interaction technologies that will allow you to realize all the main advantages of this technology, such as minimal processing time, the speed of receipt of already formed batches from various suppliers to the end user and minimizing SW storage. This factor is also important in connection with the trend to spread the demand for food products without preservatives and harmful additives, which provides for a minimum shelf life.
To a large extent, the distribution centers of 3PL operators also use standard cross-docking ( Figure 2). Its technology is much simpler and takes less time but does not For a formalized mathematical description of the processes of movement of goods, it is necessary to additionally know the correlation functions K(t, t ).

To calculate the correlation function, it is necessary to mathematically describe the entire cycle of cargo movement on the DC. Since the process of loading from suppliers and shipping to consumers throughout the assortment matrix is constantly taking place, we use the pseudo-state method to model the dynamics of DC operation. To do this we introduce the time TU that characterizes the process being in a subset U of states It follows immediately that To be able to predict the DC activity over the extended planning horizon of the logistics operator, we will find the characteristics of the stationary mode of operation. Let us take the notation m r , equal numerically to the probability of finding the system S in a pseudo state m U in stationary mode of operation: Then we have from the expression:  To calculate the correlation function, it is necessary to mathematically describe the entire cycle of cargo movement on the DC.

Company Management System
The issue of development of the Huawei management system could arise taking into account open innovation dynamics associated with the implementation of innovative models as well as open innovation engineering models [9] regarding the growing information flows regarding the digitalization and an impact of digital technologies on the business models. The digitalization of the economy could be considered as changing business models and service delivery means and structure, increasing availability of goods and services, raising awareness of participants, increasing safety of business transactions, expanding sales markets and target audiences, reducing the cost of promoting goods and services and transaction costs and so forth [44]. Digital transport corridors are considered by experts as a system for collecting, processing and consolidating information about vehicles, goods and accompanying documents at all stages of transportation, technological operations. The format of the digital transport corridor could be treated as an information system assuming work without territorial restrictions [45]. So, the special features of the digital ecosystems should be noted including the collaboration of the participants of such ecosystems [46] allowing implementation of open innovations with mathematical modeling of logistics processes in dynamics [47].
The innovation approach on the basis of the digital technologies allowed Huawei company to create a global management system to ensure the inheritance of corporate culture and increase effectiveness of business management in order to achieve the following objectives: 1.
constant innovations, consumer-oriented and based on their needs and technological leadership, for creation of sure-fire ecosystem; 2.

maintaining corporate social responsibility and achieving sustainable social development.
The company quality goal is to make Huawei associated with high quality in the IT field. It released a resolution on integrated development and implementation of total quality management ISO 9000. It clarifies that total quality is based on the ISO 9000 standards. Quality management has to include products, engineering and all other aspects of a company. It also has to focus on the customers' needs and use strategy to manage the quality of the whole process and value chain. The "quality first" strategy is necessary to implement. Company has to constantly to increase the competitiveness of quality and serious risks. Quality standards are integrated in work process to improve its quality.
Huawei introduces requirements for the management system as part of corporate operations and permanently consolidates consumer-oriented management system, based on value creation, in order to support and improve business development. The company made the complex process system with operational and support processes, based on the best world experience [48][49][50][51][52][53].

Corporate personnel are interested in achieving high quality and contribute to constant improvement of various business systems, due to leadership development, Six Sigma and QCC (quality control charts for continuous, attribute and count data) projects, Huawei quality awards, assessment of the internal and external audit and quality culture building [54].

Mathematical Model of DC Operation
Volume of stocks i-th the product on DC is denoted as r i , i = 1, 2, . . . , n; demand volume distribution function the product z i is marked as p i (z i ). The cost of maintaining and processing i-th units both are equal to C i ; costs due to factors such as demurrage and detention or contractual penalties for non-delivery or late delivery are indicated as A i . The overall costs Φ(R), where R = ∑ r i can be calculated from the expression: Since the volume of demand for various items in the assortment matrix is usually seasonally dependent with the period T Σ , then to determine the mathematical expectation of the demand value X(t), it is convenient to apply the Fourier decomposition in the following form: by ω = 2π/T Σ , where M 0 ,µ k ,ν k -are the coefficients of the decomposition. To solve the problem of modeling DC activity, you can use a set of solutions to equations that are integrable in quadratures.

Calculation Example
Let us consider the problem of determining an economically optimal distribution center on the example of a bounded dimension. The efficiency criterion is cost minimization. It is clear that it is necessary to find a balance between the volume of storage capacity and the risk of possible losses due to the presence of penalties A i . First we will find the law of distribution of random variables of supply volumes X 1 , X 2 , X 3 provided that they are independent and each distributed evenly: (−a, a), i = 1, 2, 3. The choice of the dimension of the range n = 3 will not affect the calculation order, since the formulas are recurrent. Let us introduce the designation Y = X 1 + X 2 + X 3 . Firstly, we define the distribution law of the composition Y 1,2 = X 1 + X 2 in: Next, we get the distribution for Y = Y 1,2 + X 3 using the Simpson formula: In this way, the necessary parameters can be obtained for modeling the distribution function for any dimension of the assortment matrix. The correctness of the mathematical model is determined by the set of formalisms adopted during its formation. In the presented work, we tried to take into account the most significant factors. The demand distribution function reflects the impact of demand volatility, inventory costs reflect operating costs, procurement costs depend on logistics capabilities, the maximum warehouse volume determines capital costs, penalties are a formalized description of important points of contractual obligations and reflect the work in a competitive environment. Validation of a mathematical model implies calculations based on specific data. Since a review of the literature showed that such or similar mathematical models were not used in the design and construction of distribution centers, there is every reason to believe that in reality there is a significant reserve for increasing their economic performance. This requires the collection of data on the market situation and business parameters. In the proposed work, a calculation is carried out using a mathematical model based on typical economic indicators and probabilistic characteristics of changes in market demand.

Practical Calculation on a Computer Using Mathematical Modeling
We will program the above method assuming the random nature of receipt and shipment of goods to DC. For simplicity, we use relative units of measurement, which will expand the scope of the results.
The values of the optimal volumes of emergent reserves that determine the size of DC storage are marked on the graph (Figure 3). Shown here is a set of calculation results carried out for various conditions of the influence of market uncertainty on the total expenses associated with maintaining the required level of reserves at the distribution center. On the graphs, DC parameters are marked that correspond to the minimum probable costs, which allows the use of calculation algorithms for the design and construction of logistics network nodes. As expected, the degenerate case of no costs for overdue or missing goods at the time of fulfillment of obligations is reflected in zero inventories. In all other cases, the minimum is achieved if a balance is maintained between the volume of work or the cost of maintenance and the likely losses due to partial dissatisfaction with shipment requests. In addition, the results also clearly show that as the relative share of penalty costs increases, the volume of emergent stock increases (  Figure 3. Dependence of expenses on the distribution center (DC) volume limit. Figure 3. Dependence of expenses on the distribution center (DC) volume limit.

Discussion: A logistics Hub Using the Digital Footprint Method
Discussing which research gap was present and which research gap was partially or fully closed by the findings in this article, the authors assume the following consideration. In general, the presented mathematical model is intended for use as a decision-making block in the Warehouse Management System (WMS) software. From the point of view of mathematical formalisms, such nodes of a commercial network as distribution centers or local SW of commercial enterprises differ only in the dimension of equations. If we consider such transport hubs as seaports that accept responsible storage, are engaged in the formation of commodity batches and other stevedoring competencies, then this approach also describes their activities using similar algorithms and allows optimization.
The authors suggest a formalized representation of the movement of goods and cargo taking into account real market conditions, including both uncertainty factors and the stochastic nature of the volumes and directions of flows. Stochastic modeling methods from the theory of random processes are used for the description. To develop optimal solutions, the criterion of minimizing total costs is applied. The choice of performance indicators is based on the balance of logistics and storage costs, demurrage and detention with the maximum profit from logistics activities. Calculations are performed using numerical methods of the mathematical theory of optimal processes computer simulation.
The research considers an economically optimal management of the flows of goods and cargo based on digital information about their movement. Since modern production and digital technologies implemented everywhere will allow to supply all cargo with machine-readable markings not only in the form of QR (Quick Response) or barcode but also with RFID (Radio Frequency Identification) tags, this provides a resource for specifying additional information about cargo properties, storage and transportation conditions, as well as expire date.

Discussion: Open Innovation Engineering from the Digital Footprint Method
The Open innovation concept could be considered from the point of view of the digital footprint method. The article [47]  Regarding the findings in the article with some other contributions, the authors could prove that the innovation process on the basis of the digital technologies in logistics refers to the general topic of product innovation (and the corresponding process of pioneer market shaping [55]) in the literature on open innovation. The research could be treated from the point of view of the service-dominant product in the form of a software. Generally, the topic of digital transport corridors seems to be a "hot topic" on the agenda of economists and business scholars alike, yet, a lot needs to be done since there are significant research gaps on the agenda. Undoubtedly, the implementation of innovative activities is associated with the implementation of innovative models. So, the discussion should be based on the fundamental theory being developed by JinHyo Joseph Yun who suggested the open innovation engineering model including both open-innovation engineering channels and determining ways of operating the channels through conceptual experiments [9]. The effects of the mechanism design (fundamental to the study of incentives and information [10]) are expanded and implemented for developing new business model from open innovation and Schumpeterian new combinations [11,12] as well as open innovation based business model design compass [13]. The authors take into account the Christensen's determinants of open innovation model associated with the industrial dynamics of an industry segment undergoing a process of radical technological innovation [14] unravel-ing the Chesbrough's Open Innovation concept which was initially studied by from the company-level perspective (in contrary to the closed innovation old model).
The work [56] studies the boundary conditions that determine whether open or closed types of innovation management will actually lead to the highest value for a given firm. The mentioned determinants could be considered as various internal and external constraints (situational factors) from a point of view a contingency perspective. Undoubtedly, it is important to analyze what open innovations' properties can compensate for the possible negative effect appearing from sharing knowledge with other firms because of going to reduce the potential rarity of the eventual inventions. In this regard the researchers should pay attention to the business model innovation aiming to succeed a competitive advantage on the basis of the sufficiently differentiated business model being hard to replicate for incumbents and new entrants alike [57]. We could agree that Business concept innovation is a central pillar in business model innovation [58].
Open innovation in value networks could be studied by analyzing three main issues [59]: (a) how central firms choose between different governance modes when they establish relations with partners; (b) studying value constellations being a nexus for the integration of different theoretical perspectives since they are a nexus where value creation, non-arm's-length transactions, external resource sourcing and inter-organizational networking are welded together; (c) analyzing Open Innovation at different levels and that interorganizational networks.
Reference [60] explores the network perspective for both the consideration of business models in action and such main features of business models as value creation and firm networking activities for different firms, small entrepreneurial firms and large companies.
The next steps for improving the results in consideration of future research could be creating software products for control computers in combination with the above-mentioned information about the object parameters with the purpose of developing the detailed mathematical model, the arguments for which are refined using real data. This method is also promising for higher levels of logistics, such as 4PL, 5PL. In these concepts, the logistics service provider is involved in business processes, as well as significantly expands the range of services but the physical interaction with cargo flows and their nature, mathematical description remains completely the same.

Conclusions
With the active use of digital technologies in the nodes of logistics networks starting 5-7 years ago, their implementation was carried out on the principle of replacing the people of operators on information flows. There was no scientific approach to optimization of both distribution centers' operating modes and their sizes. This work provides a mathematical description for the following purposes: -Formalize the characteristics of the stochastic flow of goods and cargo through the logistics hub. -Assess the parameters of the two main cross-docking and pick-by-line technologies in cargo handling.
The results obtained in the form of a mathematical description are the basis for the predictive determination of the seasonal change in the parameters of the load distribution functions of the nodes of the logistics network and will make it possible to calculate, with the above characteristics of flows, the volume of the distribution center that is optimal from the point of view of minimum costs, taking into account the main economic factors.

Huawei's main disadvantage is the company's risks while entering target market, owing to policy instability and local conditions on international market. Over the last 20 years, Huawei personnel have been affected due to difficulties at the target market environment. Huawei is an enterprise in developing country, highly influenced by international market in the field of low-budget products and it has an impact on the reputation. Product quality and corporate brand are underestimated. The lack of international market experience and high education expenses also have a negative impact on the company.
Recently, the USA introduced sanctions against Huawei due to economic and market disagreements between the USA and China. Huawei used to implement ARM (Advanced RISC Machine) chips in their products and now ARM ended that partnership. Such changes had a large impact on Huawei mobile phones, computers and other electronic devices. Another major fact is that in 2019 the USA banned Huawei in general and now Huawei financial risks are gradually increasing.

Model Implementation
The study of the distribution center should be carried out in conjunction with the economic calculation of the results of its activities for a long-time horizon. To do this, we will define a set of factors that affect its indicators and use them as arguments for a formalized description of the dynamics of DC operation.
Successful implementation of digital technologies in logistics depends on the quality of algorithms for managing servers. Online cargo tracking based on digital shadow allows you to not only control the entire forwarding cycle but also forecast it. The complex of information about the shipment from the manufacturer, M2M navigation in the process of moving product flows is supplemented with data on market demand. It is used to calculate the optimal economic activity of 3PL outsourcing. The proposed algorithms are universal and, importantly, scalable and invariant to operating platforms. The presented mathematical model is intended for use as a decision-making block in the Warehouse Management System of software. Since the uncertainty factor is taken into account when developing algorithms, it is possible to apply the results obtained in risk management applications. In practice, this digital concept will significantly increase the speed of delivery, the cost-effectiveness of logistics activities and provide 3PL operators with additional competitive advantages.
