| 摘 要： | 考虑有限时域下面对确定和随机两种需求类型的产品库存系统,使用动态规划法构建该系统的动态模型以求得利润最大化下的最优订货和分配策略.由于动态规划法计算时间过长且在时域滚动环境下未必最优,因此在分析了最优策略性质的基础上设计了一种启发式算法以解决动态规划法的缺陷.数值分析表明启发式算法在绝大多数情况下优于动态规划法.

| Abstract: | A periodic review inventory system with deterministic and stochastic demand classes in finite horizon was considered.A dynamic model was developed by using dynamic programming in order to optimize the ordering and rationing policy to maximum the earning.A heuristic algorithm was designed based on the analysis of the optimized policy to conquer the disadvantages of dynamic programming such as long-time running and non-optimality in rolling horizon.Numerical analysis shows that the heuristic algorithm perform... |
