本文研究了一个由一个零售商和n个“不同”顾客组成的两级供应链。零售商根据顾客的需求订购不同的易腐产品。零售商的未满足需求是部分积压的，其积压率与时间成比例。我们建立了延迟系统和独立系统的模型，以最小化订购和保留n个“非瞬时变质物品”的单位时间总平均成本函数。给出了求解模型最优解的算法。通过理论分析和数值计算，研究了变质率对库存补充策略的影响。
In this paper, we consider a two-level supply chain consisting of a retailer andn“non-identical” customers. The retailer orders different perishable products in response to the demands of the customers. The unsatisfied demand at a retailer is partially backlogged with a time-proportional backlogging rate. We formulate models for a postponement system and an independent system to minimize the total average cost function per unit time for ordering and keepingn“non-instantaneous deteriorating items.” An algorithm is given to derive the optimal solutions of the proposed models. The impact of the deterioration rate on the inventory replenishment policies is studied with the help of both theoretical and numerical results.
