Abstract

Currently, quantitative data analysis methods and the latest computer technologies can significantly improve the efficiency of logistics and supply chain management. The purpose of the study is to develop economic and mathematical models of the company’s activities to study the options for using all types of company assets, including financial ones. Methods of mathematical modeling and operations research are used. The article examines the working capital management models of a trading company, in which there is no uncertainty about the initial values, but there is an uncertainty about the parameters of the problem. The optimal solution can be obtained using the described method. The paper presents a methodology for analyzing the stability of the optimal solution, as well as an approach to assessing the risk of bulk purchases. The authors consider the developed software as a tool for finding the optimal portfolio for wholesale purchases. The algorithm used by the software tool is based on the branch and bound method.
