基于时间约束的单产品共同配送研究

随着物流业的调整发展．提高物流效率、降低物流成本逐渐成为关注的焦点。有着发达物流业的国家，如德国、美国等的实践已经证实，采用共同配送这一先进的配送模式，将能够改善在物流效率、物流成本方面所凸现的问题。在我国，共同配送体系还不完善，加之客户对于配送时间的要求也越来越高．满足客户时间要求的集约化、协同化配送就成为亟待解决的问题。文章针对这一问题，将“软时间窗”和“硬时间窗”同时引入到共同配送中，建立模型并通过算例分析对理论研究进行了实证。

Research of Single Product Common Distribution on the Basis of Time Restraint

With the rapid development of the logistics industry, improving efficiency and reducing costs in logistics gradually become the focus. Some countries, which have developed logistics industry, such as Germany and the United States, have confirmed from the practice that the Common Distribution, a kind of advanced distribution model, will be able to improve the efficiency of logistics, logistics costs by highlighting the issue. In China, the common distribution system is not yet perfect, and the delivery time for customers is increasingly higg requirements than before, intensive and coordinated distribution have been a urgent problem to be solved to meet the time requirements of the customer time. In response to this problem, the paper introduces"soft time window"into common distribution as well as"hard time window", and confirms theory study through the establishment of model and analysis of algorithms.
