Optimisation of the EOQ model when renting storage locations taking into account the factor of vehicle capacity and losses due to the immobilization of funds in stocks during the reconfiguration of supply chains

Abstract

The article presents a modification of the EOQ formula for a model with rental of storage facilities, which will allow managers operating in the conditions of crisis reconfiguration of supply chains to find the optimal inventory management strategy, taking into account the combined impact of a number of factors: the capacity of the vehicle, the time value of money when optimizing supplies and financial losses associated with funds frozen in stocks. The procedures for modifying the EOQ formula for such situations are carried out in relation to models important for practice, when payment for the order and the corresponding transaction costs of the supply chain are realized from the revenue received at the re-order interval. At the same time, necessary and sufficient conditions have been established based on which managers will be able to identify models of the specified type. The purpose of the article is to draw the attention of managers to additional opportunities to improve the efficiency of inventory management systems in modern business development conditions by considering these factors when optimizing supplies.
