A Discount Policy for Perishable Items Sold from Two Shops

다국어 초록 (Multilingual Abstract)

This paper deals with two shops dealing with single perishable product：the fresh items are sold at a list price in the primary shop and the unsold items that have reached a certain allowed age are transferred to the secondary shop to be sold at a discounted price. It is assumed that the demand rates in two shops are independent each other and can be expressed as a function of inventory level and price. With the objective of maximizing the profit under a Last-In-first-Out (LIFO) issuing policy, we develop mathematical models for the following two cases：(1) opening primary shop only and (2) opening both primary shop and secondary shop. There are three decision variables, i.e., the reduced price in the secondary shop, the allowed age at the primary shop, and the order quantities at the primary shop. A solution procedure is developed based on tabu search and its validity is illustrated through a comparative study.
