【摘要】 库存管理是超市配送中心管理中的核心问题,而传统的库存计算是通过存储论模型来解决的.这种方法对历史数据依赖性强且孤立决策.系统动力学是研究复杂系统的重要理论与方法,可以有效地解决配送中心库存的确定与控制问题.但系统动力学的政策优化问题还是沿用“试凑法”,一直没能得到很好的解决.现从系统动力学原理出发,形成对系统动力学模型政策优化的一般描述,进而将系统动力学和遗传算法相结合,探讨超市配送中心系统的最优库存和最优订货策略问题.更多还原

【Abstract】 Inventory management is a focus in a distribution center and super-market system.The traditional storing model depends on historical data excessively and managers decide separately.System dynamics is an important theory and approach to explore the complex system.The model of system dynamics can help us count and control store of distribution center effectively.The policy optimization problems in a system dynamics model,however,still follow the "cut-and-try" method,which does not work well.According to the principles of system dynamics,the paper presents a general formulation of policy optimization problem in a system dynamics model by introducing a control policy function.Combining with genetic algorithms,then,the order policy optimization in a distribution and super-market system is addressed.更多还原
