Internal changes and external contradictions of the trade organization are somehow connected with commodity stocks. That indicates the necessity of the scientific approach to their management.
The main purpose of stocks control, as one of the components of working capital, is to minimize the total costs for their purchase, delivery and storage. At the same time, delivery and storage costs demonstrate multidirectional behavior. On the one hand, an increase in the delivery schedule leads to a reduction in delivery costs per a stock keeping unit, and, on the other hand, this leads to an increase in storage costs per a stock keeping unit.
The economic order quantity (EOQ) is determined by the formula obtained by Ford Harris in 1913. However, in the control theory it is more commonly known as the EOQ model or the Wilson formula (R.H. Wilson).
And although more than 100 years have passed since the development and first application of the basic design of Ford Harris in calculating the economic size of the inventory order, the issues related to the guarantees of maintaining a low level of available resources and corresponding costs become even more urgent today.
In this article, the EOQ model is modified by expanding it depending on the order point, the inventory date and the optimization of the order model, taking into account the stochastic uncertainty.
