摘要: 本文研究了集成生产批量、配送中心定位和车辆运输路径问题的一个复杂大系统,并建立了相应的数学模型。为了便于理解和求解这一大系统,将这一系统运用Lagrange松弛法分解成了生产、配送中心和定位-路径等三个相对独立的子系统。基于次梯度优化算法提出了一种优化协调机制,实现了系统的整体优化,并进行了数值实验分析。

Abstract: In this paper,a complex large scale system integrated production lotsizing,distribution center location and vehicle routing problem is researched,and the relevant mathematic model is established.In order to underst and and solve the problem,we decompose the system into relatively independent production lotsizing subsystem,distribution center subsystem and location routing subsystem,by lagrange relaxation algorithm.A coordination mechanism based on subgradient optimization algorithm is presented, and the system is led to globally o ptimized goal.Finally,an example for this problem is given.

Key words: supply chain, production-location-routing problem(PLRP), large scale system, lagrange relaxation algorithm, decomposition and coordination
