本文討論生產率與需求有關，且需求率為一斜坡型函數之允許缺貨的退化性產品之存貨問題。因為需求率在時點t=μ時產生變動，最適生產停止時點t/sub 1/可能大於μ，也可能小於μ。所以本章將分別討論一個生產週期之生產停止時點t/sub 1/大於μ的情形(稱做Case 1)，及生產停止時點t/sub 1/小於或等於μ的情形(稱做Case 2)。我們的目的在決定最適的生產策略，使得存貨的單位時間平均總成本為最低。 This paper presents a production inventory model for deterioratingitems with a ramp type demand rate. The production rate at any instantdepends on the demand. The proposed model allows for shortages, andexcess demand is full backlogged as well. Depending on the optimalproduction stopping time t/sub 1/, two different situations may arise(l) t/sub 1/ > μ(Case 1) and (2) t/sub 1/ <=μ(Case 2). Our purposeis to find the optimal production strategy that minimizes the totalaverage cost per unit time of system.
