This article is the result of generalizing a real practical problem of optimizing the operation of a cold supply logistics network. A small (up to 100 clients) logistics company solves the problem of operational planning: during the working day (fixed time window) to provide the supply of cold (food) products from distribution centers to end consumers along well-defined routes (i.e., the logistic network graph is fixed). The company has set the following conditions for the authors. In addition to minimizing the usual transport costs, take into account also the environmental costs (associated with negative consequences for the environment) that arise during the operation of the logistics supply network. And also when deciding to use software available to the company. The case is considered when the transport tariff on each route is a linearly increasing function of the total volume of all traffic on this route. When the Nash equilibrium conditions are met, the mathematical model for optimizing the total costs of the logistics network is reduced to a convex (quadratic) programming problem. Computer implementation in MS Excel environment has been carried out. This makes it possible to carry out simulation calculations for various options for transport costs on routes, taking into account environmental costs.
The article examines the market of cold logistics in Ukraine (logistics of products, which requires compliance with special temperature conditions). The main problem faced by the authors was the virtual absence of statistical data in this sector of the economy. Therefore, for the study, one of the methods of Multivariate Statistical Analysis was applied, namely, Hierarchical Cluster Analysis. This method made it possible to make a dynamic (for 2017-2020 years) classification of the regions of Ukraine with respect to a latent indicator - the stable development of the cold logistics market. A robust division of 24 regions into three groups-clusters was obtained: “leaders”, “middle peasants”, “outsiders”. The factors-symptoms that had the most significant influence on the formation of a cluster (group of regions) of leaders were determined: the volume of exports and imports, the number of modern multi-temperature logistics warehouse complexes and the income of the population of the region. To assess the environmental impact of the functioning of the cold supply logistics network, an environmental factor was used in the analysis - the volume of CO2 emissions from transport, warehousing, postal and courier activities.

ANALYSIS OF EFFICIENCY IN THE COLD SUPPLY CHAINS OF THE ENTERPRISE The article is devoted to the study of the efficiency analysis system in the cold chains of food industry enterprises. Models of the relationship between the total costs of logistics and key performance indicators of food industry enterprises have been investigated.Economic instability and the increasing importance of the logistics component in the economies of all countries require the development of new methods for assessing supply chains in order to find effective ways to reduce costs and increase the competitiveness of enterprises. A detailed review of literature sources allowed the author to choose a method for assessing key performance indicators that gives the most accurate assessment results, and also choose the factors of argumentation in comparison with other methods of economic analysis. By modeling business processes in cold supply chains and then controlling their parameters, you can describe actions and quickly respond to changes in the external and internal environment. A set of performance indicators for an enterprise's logistics can be based o...
The paper considers the theoretical and methodological foundations of the system organization of the functioning of logistics systems based on modern technologies. The results of the research presented in the work allow us to substantiate scientifically: measures to develop domestic logistics systems of companies to the level of 3 PL and 4 PL, 5PL-service providers; model management options for a company operating as part of a logistics chain; optimize the structure of the enterprise based on the goals and tasks in the field of logistics; to study the possibilities of introducing information technologies of fixing the company to the level of 3 PL, 4 PL, 5PL-service providers. For this purpose, the paper studies the theoretical foundations of the management of logistics systems by companies, based on the outsourcing of logistics and information technology level 3 PL and 4 PL, 5PL service providers. The subject of the study is the organization of the logistics systems of companies in the conditions of economic globalization. The following research methods were used in the work: structural analysis, synthesis, comparison, economic and mathematical methods, research method related to target and synergetic principles, scientific methods and methodological apparatus of logistics management, the theory of material flow management of the methodology of economic efficiency evaluation of management and logistics technologies. The research was based on data obtained from the following sources of information: scientific publications and monographic publications of domestic and foreign scientists, materials of scientific conferences and studies, materials of periodicals, reports and analytical materials from official websites. Recently there has arisen and is becoming more and more popular a new vision of acquisition of the logistics services-the so called 4PL model. The
