DEVS를 활용한 공급망 내 정기 주문 정책 모델링 및 시뮬레이션

초록

The enterprise seeks profit and aims to maximize it. Inventory costs are among the various costs that enterprise can incur. And this inventory cost refers to various costs incurred due to inventory. Inventory management aims to reduce inventory costs while satisfying customers' requirements. Efficient inventory management is an essential issue for enterprise to maintain competitiveness and profitability from a management strategy point of view. If inventory management is not carried out appropriately and results in inventory shortages, the enterprise will be unable to meet customer requirements, ultimately leaving it at a disadvantage in the competition. Therefore, from this perspective, appropriate inventory management can be seen as important. In this paper, we propose modeling a periodic review inventory policy in the supply chain using DEVS, which has advantages in verification, validation, and reusability of the model. If the simulation is performed according to the method designed in this paper, it is expected that enterprise will be able to analyze the results and check their own inventory management strategies. In addition, it is expected that changing various factors, such as the target inventory level, will help in preparing the optimal inventory management plan through simulation.
