摘要

本論文提出一個存貨模式去研究當擁有的損壞商品具有時間相依的二次需求及允許遞延支付，模式中允許缺貨且擁有部分備用品；最後本研究提出一個具備成本最低的最佳化政策。本研究的目標包含考慮三種不同的機率損壞函數並找出其對應成本。最後舉例說明本研究的優點，並進行敏感度分析以檢測當模式參數變化時，此三種模式最佳解的變化情形。

In this paper an inventory model for deteriorating items with time dependent quadratic demand and permissible delay in payments is developed. Shortages are allowed and are partially backlogged. An optimal policy that minimizes the total cost is developed. The objective of this study is to consider three different types of continuous probabilistic deterio-ration functions and to find the associated total cost. To illustrate the proposed model some numerical examples are given. Sensitivity analysis of the optimal solutions with respect to major parameters are carried out and comparison is made between the three models.
