不确定条件下外协生产库存系统控制策略与参数优化

针对协作企业生产能力和运输时间不确定条件下的外协生产库存系统优化控制问题，提出了一种基于生产点和生产批量的生产库存控制策略。用统计概率分布对协作企业生产能力和运输时间的不确定性进行描述，以库存成本、生产准备成本和协作企业生产能力损失成本最小为目标，建立了生产能力和运输时间随机变动条件下生产库存系统控制策略的参数优化模型，设计了一种基于仿真的控制参数优化算法，通过实例对生产库存系统控制策略及控制参数优化算法进行了验证，并分析了生产点和生产批量等参数变化对与外协生产库存系统性能的影响。

Control strategy and parameters optimization outsourcing production inventory system under uncertainty

This paper proposes a control strategy for the optimal control of the outsourcing production inventory system based on production point and production batch. The statistical probability distribution is used to describe the uncertainty of the production capacity of cooperative enterprises and the transportation time. The optimization model of the control parameters is developed with random production capacity for cooperative enterprises and random transportation time in order to minimize the holding cost,setup cost as well as the cost of production capacity waste. A simulation-based control parameters optimization algorithm is designed to solve the proposed model. The control strategy of production inventory system and the control parameters optimization algorithm proposed are validated by an example. We analyze the influence of the variation of the production point and production batch to the performance of the outsourcing production inventory system.
