基于投产点库存的随机综合生产计划模型研究

以企业基于投产点法的生产与库存控制策略为研究起点,分析了随机需求条件下生产系统服务水平与库存水平的数量关系,并将产品在计划期间的平均库存量引入综合生产计划模型。模型中计划期产量是与产品需求具有相同分布的随机变量,模型的优化目标是通过确定最佳的投产库存量和生产系统服务水平,求得相应的计划期产量区间。提出了模型的计算机辅助求解算法,并采用案例分析验证了模型的有效性。

Research On the Model of Reproduction-point based Stochastic Aggregate Production Planning

The reproduction point based production and inventory control policy is analyzed as the starting point for further research,followed by the analysis on the quantitative relation between service level and stocks of the production system in stochastic-demand environment,and the average inventory in planning periods is invited into the aggregate production planning model.The planning out put in every period is stochastic variables having the same distributions with the product demands.By computing the optimal reproduction points and service levels,the optimizingaim of this model is to determine the optimal production intervals for each product in each period.Solution algorithm is proposed and an numerical case is used to validate the model.
