协同生产计划调度系统及其关键技术

分析了网络化制造环境下生产计划调度的需求和特点,提出了一种面向动态联盟的协同生产计划调度系统的体系结构,并深入研究了实现协同生产计划调度的关键技术.首先对协同信息交互的立体结构和基于XML(eX-tensible Markup Language)的信息交互机制进行了分析,引入基于协商的协调机制和冲突消解策略,最后探讨了计划调度的快速优化算法,以实现对生产计划调度系统的协调优化.在此基础上,建立了原型系统,对上述关键技术进行了应用验证.应用表明,该系统具有良好的扩展性和适应性,能够实现动态联盟生产过程中的自治和协同.

Collaborative Production Planning and Scheduling System and Enabling Technologies

Based on an analysis of new requirements and characteristics of production planning and scheduling(PPS) on networked manufacturing mode,a new collaborative PPS system model for dynamic alliance is proposed and the enabling technologies are delivered.To achieve the collaboration and optimization of PPS system,the information exchange of three-dimensional structure and collaborative mechanism based XML(eXtensible Markup Language) were firstly analyzed,and then coordination mechanism based on negotiation and strategies of conflict resolution were introduced.Finally,PPS rapid optimization algorithm was discussed.Based on the theory,a prototype system was designed and the enabling technologies were verified.The application shows that the system has a good scalability and adaptability to realize the autonomy and collaboration during the production process.
