碩士 === 健行科技大學 === 工業管理系碩士班 === 106 === This study mainly discusses the conditions for allowing advance payment-cash-credit trade conditions, establish an inventory model for degenerative goods that considers changing demand and has a lifespan. This article considers two inventory models, Firstly, assuming that the demand rate and freshness are related to the shelf display level, an inventory model for deteriorating items with effective deadlines is established. The main purpose is to determine the optimal length of time, the length of the replenishment period and the order volume so that the retailer''s total profit for the year is the maximum. Then, adding the sales price to explore, further, we use several practical examples of enthalpy values to clarify the solution and perform sensitivity analysis on the main enthalpy. After that, through numerical analysis, we find out the optimal decision and the optimal total annual profit under the above credit transaction conditions. Due to the complexity of the two models, this study will propose an algorithm to find the best solution. Finally, according to the results of numerical analysis, to find out the relevant management implications and research conclusions, and hope to provide a reference for decision makers when formulating ordering strategies.
