Abstract: According to the service-oriented mind in cloud manufacturing, aiming at the relation coordination problem of coordination production in distributed zones, a kind of distributed coordination scheduling technology based on dynamic manufacturing ability service was proposed with the guidence of cloud manufacturing. Through analyzing dynamic service sharing of manufacturing resource and relation coordination problem, a general framework of coordination scheduling technology based on service'manufacturing resource was established. The filtering rule considering location and ability of service resource was researched, and the job scheduling technology combined idle occupancy with inserted adjustment oriented to coordination production was formed. The automatic planning method under occupied resource was put forward to solve scheduling problems caused by limited manufacturing resource. Aiming at the frequent occurrence disturbance events in production process, time tolerate technology to reduce influence scope of production disturbance as well as dynamic scheduling adjustment technology were proposed, thus quick response treatment problem under dynamic changes of manufacturing resource service was solved. The proposed technologies were verified by examples.

摘要: 基于云制造技术中面向服务的思想,针对现有异地分布多车间协同生产计划的关联协调问题,提出并建立一种以云制造思想为指导的基于动态制造资源能力服务化的分布式协同生产调度技术。通过分析多车间协作生产下的制造资源动态服务共享和关联协调的问题,建立基于服务性制造资源的协同生产调度技术总体框架;提出服务性资源的地域和能力相结合的筛选规则,形成面向多车间协同生产的空闲占用和插入调整相结合的作业排产技术;提出资源指定占用下的作业排产处理技术,解决了协同生产环境下特定车间基于制造资源能力局部能力占用的调度排产;针对生产过程中频繁发生的突发事件,提出以降低生产扰动影响范围的时间容忍度技术及基于移动处理方式的动态调度方案调整技术,解决了制造资源服务动态变化下的快速响应处理问题。通过应用实例对以上关键技术进行了验证。
