摘要/Abstract

摘要： 第三方物流为了给客户提供正确且高效的服务,对物流进行了领域整合,建立了连接供应商和顾客的多级物流网络,网络包括了运输、流通加工、储存及配送等物流子系统。为降低网络系统成本,提高服务效率,针对网络中节点和通道上固定的物流供给能力,设计了以运营成本为目标的优化模型,通过变分不等式求出了最佳的物流组织方案,同时根据运行方案对网络中基础设施进行了重新设计改造,避免了资源不必要的浪费。最后通过算例对模型和算法进行了验证。

关键词: 物流管理, 网络优化, 变分不等式, 第三方物流

Abstract: In order to provide accurate and efficient service for customers, third-party logistics integrates the logistics areas and establishes the multi-level logistics network connecting suppliers and customers, which includes transportation, distribution processing, storage and distribution. For reducing the cost of network systems and improving service efficiency, the article designs an optimize model aiming at minimum operating costs, with the constraints of fixed logistics supply capacity for the network nodes and channels. The model obtains the best logistics organization program by variational inequalities, and at the same time it also re-designs and transforms the network infrastructure according to the running program, avoiding the unnecessary waste of resources. Finally, a practical example is given to validate the model and algorithm.

Key words: logistics management, network optimization, variational inequalities, the third party logistics
