In this article, we consider a two level supply chain to evaluate the impact of postponement strategy on the retailer. Here the cost parameters are fuzzified. Signed distance method is used to defuzzify and to obtain the estimation of the total cost in the fuzzy sense. The common variable production cost, common fixed cost and the common unit holding cost per unit time are assumed to be fuzzy in nature. Inventory models are formulated for postponement system and independent system such that the total average inventory cost function per unit time is minimized. Algorithms are given to derive the optimal solutions of the proposed model. Theoretical analysis and the computational procedure helps to study the impact of deterioration rate on the optimal inventory policies. A comparative study between the postponement system and independent system considering fuzzy costs is also made.

使用具有模糊成本的延期策略进行有效的库存管理

在本文中,我们考虑一个二级供应链来评估延迟策略对零售商的影​​响。这里的成本参数是模糊的。符号距离法用于去模糊化,得到模糊意义上的总成本估计。假设共同的可变生产成本、共同的固定成本和共同的单位时间单位持有成本在本质上是模糊的。为延迟系统和独立系统制定了库存模型,以使单位时间的总平均库存成本函数最小化。给出了算法来推导所提出模型的最优解。理论分析和计算过程有助于研究劣化率对最优库存策略的影响。
