【摘要】 分析了现有工艺计划与车间作业计划的系统集成模型,建立了企业生产工艺计划与作业计划的层次结构,提出了面向车间作业计划的动态、分布式工艺计划与车间作业计划集成模型。将工艺计划与基于周期和事件驱动的动态作业计划相结合,把改进的离散化粒子群算法引入车间优化作业计划运算,使集成模型中生产作业计划与控制功能得以实现。实例证明了集成系统的可行性和有效性。更多还原

【Abstract】 The integrated model of process planning and job shop scheduling system in existence was analyzed.The hierarchy structure of process planning and job shop scheduling was constructed in the integrated model.An integrated model of distributed and dynamic process planning and job shop scheduling was proposed.It’s combined process planning with dynamic rolling windows scheduling based on period and event-driven.The improved particle swarm algorithm which was dispersed to suit for job shop schedule was introduced to job shop scheduling operation.Consequently,the function of job shop scheduling and control of the integration module was realized.Finally,feasibility and validity of the integrated system was validated by an example.更多还原
