A Compromised Decision-Making Approach to Third-Party Logistics Selection in Sustainable Supply Chain Using Fuzzy AHP and Fuzzy VIKOR Methods

With the effects of the COVID-19 pandemic, the e-commerce trend is driving faster, significantly impacting supply chains around the world. Thus, the importance of logistics and supply chain functions has been amplified in almost every business that ships physical goods. In Vietnam, the logistics service sector has seen rapid expansion. Since more and more businesses are seeking third-party logistics (3PL) providers to outsource the logistics functions, this article aims to offer decision-makers an integrated and consistent model for evaluating and selecting the most efficient 3PLs. To this end, the authors exploit a hybrid multi-criteria method which is fuzzy analytic hierarchy process (FAHP) and fuzzy vlsekriterijumska optimizacija i kompromisno resenje (FVIKOR) while examining the most influential and conflicting criteria regarding economic, service level, environmental, social, and risk aspects. Fuzzy information in the natural decision-making process is considered, linguistic variables are used to mitigate the uncertain levels in the criteria weights. First, FAHP (the weighting method) is adopted to evaluate and calculate each criterion’s relative significant fuzzy weight. FVIKOR (the compromised ranking method) is then used to rank the alternatives. The combination of FAHP and FVIKOR methods provides more accurate ranking results. As a result, reliability and delivery time, voice of customer, logistics cost, network management, and quality of service are the most impactful factors to the logistics outsourcing problem. Eventually, the optimized 3PLs were determined that fully meet the criteria of sustainable development. The developed integrated model offers the complete and robust 3PLs evaluation and selection process and can also be a powerful decision support tool for other industries.

CHAOTIC STATES OF A MULTILAYER NEURAL NETWORK

The study of the influence of learning speed η on the learning process of a multilayer neural network was studied. The program for the multilayer neural network was written in Python. We determined the speed of learning at which the best learning is observed. To analyze the impact of learning speed on the learning process, a logistic function was used, which describes the doubling of frequency. It is shown that the learning error function is characterized by bifurcation processes that lead to a chaotic state at η> 0.8. The optimal value of the learning speed is determined, which determines the appearance of the process of doubling the number of local minima. Increasing the number of hidden layers and the number of neurons in each layer does not lead to a radical change in the diagram of the logistics function, and hence the optimal value of the learning speed. It is shown that the increase in the number of hidden layers, as well as the number of neurons in them, with increasing speed of learning is accompanied by the appearance of a chaotic state. The chaotic state is characterized by the lack of a learning process. Using the Fourier transform of the error function, the bifurcation process depending on the learning speed was investigated. On the basis of these researches the program for definition of size of optimum speed of training of a neural network is developed. The text of the article adds program codes for a multilayer neural network with the ability to build a branching diagram and a program to determine the presence or absence of the learning process, taking into account the value of optimal learning speed and error. Key words : multilayer neural network, optimal learning speed, bifurcations, chaotic states.

The article is devoted to study and development of a formalized model of organizational and economic conditions to ensure effective management of logistics functions. The author determined that logistics functions are realized through the prism of logistics operations, which are divided into external and internal. It is noted that internal logistics operations are carried out under the influence of internal organizational and economic conditions (efficiency of customs in documentation, trade and transport infrastructure, ease of organization of international shipments, competence and quality of logistics services, the ability to track goods, the frequency with which goods arrive at recipients). scheduled or expected delivery time). The application of the logistics approach involves the creation of appropriate organizational conditions. The concept of logistics is a system of approaches to streamlining economic activity by optimizing flow processes. It is defined by managers as an effective motivational approach to management in order to reduce production costs. This concept becomes the basis of the company's economic strategy: logistics is used as a tool of competition and is seen as management logic for the implementation of the plan, distribution and control of financial and human resources. This approach ensures close coordination of logistics and production strategy. Effective management of logistics functions includes the flow of goods and services. It covers an ordered sequence of steps from the procurement of raw materials to the finished product, so that it provides value to the customer. Logistics management allows you to establish strong communications and supplier relationships, helping to avoid shipment delays and minimize logistical errors. Efficient logistics provides the best bargaining power to get the best prices and goods in the shortest possible time. During the production processes and execution of orders, logistics managers need to ensure the efficiency of material flow. Optimizing the flow of goods allows you to reduce the delay of goods in the warehouse, minimize transportation costs and ensure the preservation of stocks. By balancing capital investment, maintaining the required level of service and taking into account the variability of supply and demand, companies can significantly improve inventory turnover, service level and significantly reduce costs.

Аналіз динаміки та факторів впливу на трудові ресурси Київської області

The article in question continues the authors’ study of the refitting model for the Kyiv region aa for searching for and analyzing the factors that affect a number of labor resources in the region, their intra-regional movement, outflow and inflow. The primary assumption in the refitting model for modeling the number of labor resources in economic sectors was the constant proportions of the number of employees in each sector to the total labor force and the functional dependence of the total number of employees on the total population in the Kyiv region using the logistics function. Such assumptions were sufficient for carrying out the initial modeling and analysis of the results, but they are not insufficient to obtain more accurate results that could be relied on to make decisions in the economic policy in the region. Therefore, there is an urgent need for a more detailed analysis of the labor resources dynamics, and for the search of new factors affecting them. Thus, we have analyzed socio-economic indicators of various activities at the regional level and balanced them against the number of full-time employees involved in the main industries represented in the region. Mutually conditioned influence was found between indicators in education and the two main economic sectors: agriculture and health. Highly correlated connections have been found, which are determined by the number of employees in health care, transportation and environment. The potential impact of sociodemographic and migration processes on the number of employees in the abovementioned industries is analyzed. The main reasons why tax burden indicators and local budget expenditures influence the agricultural sector, as well as the region as a whole, are enumerated. Options for improving the refitting model for the Kyiv region are suggested, namely the introduction of a production institutional function with tax burden factors. A multifactor regression model has been developed to predict the number of full-time employees in the region based on statistical indicators of education, health care, and environment, as well as sociodemographic factors.

Стратегія інтеграції терміналів морських портів як напрямок підвищення їх ефективного функціонування

It has been proven that in the context of globalization of production and increasing consumption, the logistics and transport industry is faced with the task of satisfying the complex demands of consumers. Manufacturing enterprises are recognizing the need for effective supply chain management in response to a globalized economy and competition, and hence the need to adopt new strategies such as supply chain management and global sourcing and outsourced logistics functions. First, we will structure the existing research on the selected topic. Such a literature review should provide a basis for and identify changes in research trends. The systematization of scientific literature on terminal operations and port efficiency provides justification for specific popular areas, but does not cover all problematic issues. Port management reforms continue to take place in different ways, depending on the situation in the country or region. Thus, maritime researchers increasingly tackled port-related problems in the context of supply chain management or port research. Based on these studies, three approaches to the philosophy and practice of supply chain management can be distinguished: studies on the impact on the shipping and port industry, the application of supply chain management concepts and models for port research, and the integration of supply chain activities. Researching the Impact of Supply Chain Management on the Port Industry. Examines the impact of supply chain management strategies adopted by manufacturing companies on the port industry. He typically views supply chain management as a phenomenon that occurs outside of port operations, and analyzes the dynamics among market players when exposure is externally. Research on the application of supply chain management concepts for ports. Consider supply chain management concepts and models as analytical tools for addressing and expanding port operations and management issues. Based on the position that the port industry has been significantly influenced by supply chain management practices and accepts this approach as the dominant logistics perspective. Research on supply chain integration activities. This approach also views ports as an extended system that interacts with other parts of the supply chain. In addition, this approach recognizes the integration of supply chain management and the integration of supply chains as phenomena that can take place in ports along the supply chain and views ports as a holistic system that actively participates in the phenomenon under study. A port-to-supply chain integration strategy must be firmly based on a strong focus on supply chain integration within individual seaport terminals. Successful implementation of this strategy necessarily implies a significant increase in terminal productivity.

Digital Logistics Approach to Energy Service Socio-economic Mechanisms

The article discusses the activities of energy service companies, which is aimed at saving energy resources and improving energy efficiency. The article also discusses the sources of investment projects of energy service companies and what specific services are provided by energy service companies. Schemes of logistic chains have been built, the links of which are the customer, energy service company, bank / investor, resource provider, consumer / customer. We propose to improve the model of the logistics chain. The traditional logistics chain is a linear-ordered set of legal entities and individuals that perform logistics functions and operations to conduct material and information flows from the supplier to the consumer. That is, we understand that the links of a simple logistics chain follow each other, thus the links of the chain can contact and perform any actions only in such a sequence. Due to the approach of the traditional logistics chain, problems arise, since the information may reach in a distorted state, or it may not reach at all. We suggest logistics approach to energy service management based on the principles of digital approaches which could be developed from the famous research papers of A. Borovkov. This model is interesting because the analytical center acts as the core in this chain, which translates the information received for everyone. Conclusions are drawn on the relationship between energy conservation, quality and investment. Attention is paid to finding a new approach to energy service from the concept of digital core in logistics network.

Modelling the Impact of Climate Change Risk on Supply Chain Performance

Climate change is among the top global risks due to its growing adverse impact on businesses. However, few empirical studies address this imminent risk from a supply chain perspective. Due to a lack of established approaches for capturing complex interaction between climate change risk and supply chain performance, a three-phase mixed methodology approach was attempted. A cognitive map first captured the inter-relationships based on a mental model established by a group of experts. Later, a survey gathered from industry practitioners assessing causal relationships identified key climate change factors and most influenced supply chain performance dimensions. Finally, a system dynamics model supported by multiple case scenarios assessed the implications of climate change on supply chain performance. The results indicated a significant reduction in the availability of natural resources/raw material and capacity, leading to increase in stock-outs, inventory costs and bottlenecks disrupting procurement, manufacturing and logistics functions. Supply chain performance captured through efficiency and effectiveness shows a negative trend with increasing climate change consequences. The systems approach followed in this paper contributes by providing a quantitative model for assessing the impact of climate change risk on supply chain performance.
