Optimization of wholesale purchase management taking into account uncertainty and risk

Abstract: One of the indicators of the efficiency of the enterprise in the conditions of market relations is the profit for a certain period of its work. If we consider retail enterprises, then commercial profit, in particular, depends on how efficiently the working capital of the enterprise was used (including the attracted credit resources for wholesale purchases, as well as the pricing policy for the sale of goods in the retail network. A number of models and methods for optimizing wholesale purchases of a trading company have been formed, taking into account the demand for goods, restrictions on the amount of working capital used and restrictions on the storage capacity. The paper will consider both deterministic models and situations related to non-deterministic demand and changing retail price of goods. In this situation, multi-criteria optimization methods and methods for analyzing the stability of solutions under local perturbation of the initial parameters of the model will be used. As an illustration of theoretical models and methods, examples of the construction of optimal solutions are proposed. Keywords : supply management, multi-criteria optimization, wholesale purchases
