不确定条件下循环供应链模糊自适应生产计划调度

Fuzzy adaptive production plan dispatching of cycle supply chain under uncertainty conditions

首先,建立了循环供应链下生产计划调度模型和状态方程,通过模糊量化因子整合了正向和逆向生产计划,分析了循环供应链中存在的不确定性.然后,设计一种模糊自适应生产计划调度模型,对循环供应链生产计划的需求信息、回收信息、库存信息和生产信息进行模糊化,通过对生产计划量的自适应比例-积分-微分处理,提高了生产系统的产出对需求信息及回收信息的快速响应.最后,对该模型的应用进行了讨论和仿真验证.

A production plan dispatching model and its state functions of cycle supply chain are constructed, and the positive and reverse production plan are integrated by using fuzzy numerical factors. Then the uncertain factors of cycle supply chain are discussed. Hence a fuzzy adaptive model of production plan dispatching is presented, in which all the information including demand, recycle, inventory and production are fuzzy. The response performance of the production System to the demand and recycle information is improved by using an adaptive proportional-integralderivative controller. The applicability of the proposed method is discussed, and is verified by a numerical example.
