Collaborative Production Planning and Scheduling System and Enabling Technologies

Abstract:

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.
