FORMULATION OF COMMON OPTIMIZATION PROBLEM OF RETAIL CHAIN LOGISTICS
The paper investigates the efficiency of retail chain logistics. Inventory management optimization problems, transport planning and delivery routes are considered like independent as a result, general logistics costs are often not minimal. The aim is to study the formulation of the problem overall optimization of retail chain logistics. The methodological base of the research was the analysis and synthesis as general-logical methods of scientific knowledge, and modeling and formalization as methods of theoretical knowledge. The paper also used the method of potentials, simplex method, and branch and bound method. As a result of investigating there has been proven inefficiency of approach to optimizing logistics enterprise reporting in certain areas of logistics activities. The optimization criteria of investigating problem have identified, and there have been modeled objective function in the optimization criteria of minimal costs. For the problem of the above type there has been analysis of factors influencing the final decision in the context of the reporting segments of enterprise logistics. According to the results, there is relevance of search methods for solving the problem of optimizing the overall logistics of the enterprise under consideration. In addition, it can be assumed that the resulting method of solution may not be formalized in the form of mathematical functions, and inequalities.
