摘要： 探讨了第三方物流服务商综合前向及逆向物流活动降低物流总成本的问题,建立了物流服务一体化网络系统模型。模型允许两点实际距离非直线距离,并假定市场需求及产品返回数量随机分布。由于该问题为NP-hard,设计了遗传算法并讨论了算法收敛性,最后给出了一个数值算例。
关键词: 第三方物流, 一体化物流网络, 前向物流, 逆向物流, 遗传算法
Abstract: How to integrate forward and reverse logistics to decrease the total cost of third party logistics service providers is discussed.A mathematic model is provided without the assumption of straight-line distance.Demand for product and return amount of product are assumed to be distributed stochasticly in this model.Then a genetic algorithm is developed to solve this NP-hard problem and its convergence is discussed.At last a numerical example is available.
Key words: third party logistics, integrated networks, forward logistics, reverse logistics, genetic algorithm
