摘要
高科技产品在存贮中由于式样过时、技术发展或者新产品的推出,其价值会不断减少,即发生无形变质。本文用斜坡型函数来假设高科技产品的S型需求曲线,用持有成本不断增加来表示存货的价值损失,建立了高科技产品的变质库存模型,并提出了最优解的求解方法,最后举数字实例进行了说明。
An order-level inventory system for high-tech items was developed in this article. This problem assumed a fixed life cycle and a perishable product which value deteriorated as the item got aged. Solution for this type of problem was worked out by capturing the deterioration in value by increasing holding cost. The S-curve demand of high-tech products was represented by ramp type demand. Numerical example was provided to illustrate the solution procedure.
