摘要
基于产品非立即变质的特征,构建需求依赖于变质时间的多品种联合补货库存模型,目标是使单位时间内的总成本最小.由于联合补货问题是NP难题,且考虑变质使问题变得更加复杂,针对这一难点,采用一种截断泰勒级数的方法对目标函数的指数项进行简化,提出一种基于定界的启发式算法求解模型,并通过数值案例验证算法的有效性和实用性.最后对主要参数的敏感性进行分析,为非立即变质品的零售商在实施联合补货时提供有益的管理建议.
Based on the property of the non-instantaneous deteriorating products, a multi-item joint replenishment model is developed under deterioration-time-dependent demand, aiming to minimize the average total cost. Joint replenishment problem is NP-hard, in particular, deterioration increases the complexity of the problem further. In response to this difficulty, the truncated Taylor series expansion is used to simplify the exponential parts of the objective function and a bounds-based heuristic algorithm is developed to solve the proposed model. Finally, sensitivity analysis of key parameters is conducted, which provides useful management suggestions in the implementation of joint replenishment for the retailers of non-instantaneous deteriorating products.
