Introduction: Hospitals and medical centers are important in terms of quantity and quality of the services they provide. Therefore, inventory control is a process that ensures that the required inventory are available to the operational departments by considering the factors of time, place, quantity, quality and cost. The aim of this study was to reduce the cost of hospital with a control approach to planning available hospital inventories.
Materials and Methods: In this study, an improved optimized model with objective function was used, which includes inventory cost, costs and orders. Therefore, the inventory of ten most important items of operating room requirements was considered. To solve the model, the variable neighborhood search method was used with the approach of reducing hospital costs in MATLAB software.
Results: 10 types of most expensive goods used in the operating room were examined. Finally, according to the average demand of the studied goods in the year, a certain amount of inventory and the number of orders for each of them was obtained.
Conclusion: The variable neighborhood search algorithm answered in less than 5 minutes and by examining the quality of the answer, it shows that this method has an acceptable performance in solving this problem. Finally, the hospital did not face a shortage of goods during this period, despite heavy sanctions. Therefore, this method can be used to solve the problem of inventory control in the operating room of the hospital.
