Optimal order quantities considering complementary orders under TWO suppliers' disruption risks

초록

This paper investigates the determination of the optimal order quantity for a vendor due to the disruption risks of the supplier. The optimal order quantity is determined by minimizing the initial supply cost for each supplier, the supply cost for the complementary order, the stock disposal profit, and the total expected cost reflecting the inventory depletion cost. In order to determine the optimal order quantity, the problem is formulated as a mathematical model, and an optimal ordering strategy is derived through mathematical analysis based on the probability of supplier disruption. In addition, the adequacy and validity of the mathematical model are demonstrated through numerical experiments. © 2020 ISSN 1881-803X.
