摘要 库存-路径问题是研究在供应商管理用户库存策略下,供应商如何合理安排长期库存及配送计划的一类问题,属于NP-hard类问题,也是运筹学领域中研究最活跃的方向之一。本文以零售商系统下随机需求的IRP为研究对象,提出了一种基于马尔科夫决策过程与修正的C-W节约算法的启发式分解算法,并给出了相应的数值算例。 The Inventory Routing Problem(IRP) is a problem for the supplier how to reasonably allocation long-term plan of inventory and distribution under the Vendor Managed Inventory(VMI) strategy. IRP belongs to NP-hard problem and is one of the most active directions in the OR realm. The article explores the stochastic demand IRP in Retailer System (R-system), and presents a separation heuristic algorithm based on Markov Decision Process(MDP) and modified C-W algorithm. Finally, the article lists a numerical example of the algorithm.
