摘要
柔性车间具有的机器柔性选择等柔性特点,使动态随机干扰下的车间调度问题更具有灵活性和优化空间。本文针对柔性车间生产系统的动态随机事件的干扰,对车间受影响程度进行量化分析和判断,针对车间调度的调整提出了基于免疫度的规则导向策略,以确保实际生产计划的健康执行。首先本文根据动态随机的干扰环境对车间系统的干扰程度,提出免疫度的概念,以免疫度值作为系统的自修复调度与调度调整的判定依据。在调度调整中,根据当前生产的状态,进行以规则为导向的动态调整,合理选择调度方式,以提高车间调度调整与车间实际目标需求的契合度。
The flexible characteristics of flexible flexibility in the flexible workshop make the workshop scheduling problem under dynamic random disturbance more flexible and optimized.In this paper,the dynamic random events of the flexible workshop production system are used to quantitatively analyze and judge the degree of influence on the workshop.Based on the adjustment of the workshop scheduling,a rule-based strategy based on immunity is proposed to ensure the healthy execution of the actual production plan.Firstly,according to the degree of interference of the dynamic random interference environment to the workshop system,the concept of immunity is proposed,and the immunity value is used as the basis for the self-repair scheduling and scheduling adjustment of the system.In the scheduling adjustment,according to the current production state,the rule-oriented dynamic adjustment is carried out,and the scheduling mode is reasonably selected to improve the fit of the shop scheduling adjustment and the actual target demand of the workshop.
