基于事件驱动的制造资源冲突实时消解方法

Real-time manufacturing resource conflict resolution based on event-driven mechanism

目前调度规则和算法虽然可以避免常规的制造资源冲突,但是当系统运行过程中出现突发事件时(如设备故障、急件插入等),需要利用相关策略消解制造资源的冲突。采用事件驱动的方法,实时控制设备状态,避免制造资源冲突。同时建立消息队列,把资源冲突问题转化为队列排队问题,实现资源与资源的交互处理。引入基于规则、约束和实例的混合消解策略,以消解制造系统运行中出现的冲突问题。

Although the current scheduling rules and algorithm were able to avoid regular manufacturing resource conflicts, strategies to resolve manufacturing resource conflicts were also needed when unexpected errors and faults occured in system operation process. Therefore, an event--driven mechanism was introduced to the operation of interception, analysis and resolution of resource conflicts. Then, the resource conflict problem was transformed into queue problem to realize interaction among resources by setting up a message queue. Finally, a hybrid resolution strategy based on rules, restrictions and instances was introduced for conflict resolution in manufacturing system operation process.
