      abstract = {Purpose. The purpose of the article is the improvement of  the methodological approach for determining the optimal raw  material area in the logistics system of a milk processing  enterprise using economic-mathematical tools. Methodology /  approach. The research is based on the applying such  methods as analysis, synthesis, generalization, induction,  deduction – to determine the content and subsystem of the  logistic system of milk processing plant, factors of the  size of the raw material area of the milk processing  enterprise, formulating conclusions regarding the  methodological approach to assessing its rational size;  economic-mathematical modeling and cluster analysis – to  determine the rational size of the raw material area of the  milk processing enterprise; graphic – for a visual  presentation of the cluster analysis of the raw material  zone of the milk processing enterprise according to the  Ward’s method. The research was carried out on the basis of  statistical data of the Main Department of Statistics in  Chernihiv Region, reports of agricultural enterprises of  Chernihiv Region and data of the authors’ own observations  for 2011–2021 (for the calculation of some indicators, data  for 2020–2021 were used). Results. The peculiarities, role  and tasks of logistics in the dairy sub-complex were  determined, a conceptual model of the logistics system for  the milk processing plant was developed, which consists of  functional and provisional subsystems and covers  production, purchasing, transport, certification, storage  and processing processes, minimizes logistical risks. In  order to identify reserves of the optimization of the raw  material area, a cluster analysis was conducted (the Ward’s  method was chosen as the clustering method), based on data  on the volume of milk purchases, distance from the factory  and potential opportunities for expanding the raw material  area. The economic-mathematical model was designed, which  allows determining the optimal raw material area of the  processing enterprise based on the criterion of minimum  transport costs for the delivery of dairy raw materials, as  well as determining the optimal structure of dairy  production based on the criterion of minimum technological  costs of processing raw materials in the production of  various types of milk products, taking into account the  volume of consumer demand. The economic-mathematical model  was tested and used to determine the rational distance of  milk producers from the milk processing enterprise at a  distance of 46–56 km in the studied region. Originality /  scientific novelty. The methodical approach to determine  the optimal raw material area in the logistics system of a  milk processing enterprise has been improved by using  economic-mathematical tools and applying cluster analysis  according to the Ward’s method.  Practical value /  implications. The results of the study can be used to  calculate the optimal raw material area of milk processing  enterprises, which will contribute to the sustainable  development of the dairy sub-complex, of all its  participants, from producers of raw materials (milk) to the  final consumer.},
