Job Shop Scheduling Scheduling System

Management automation is the crucial core of CIMS, which directs other parts in the system working in harmony. The Computer-Aided Production Planning and Controlling system is the key technology of management automation. As one of the most important topics on information integration in CIMS application projects, Planning and scheduling is the center of management automation, a lot of domestic and international scholars have made plenty of research on the method of scheduling.Following the development of the workshop scheduling system in integrated environment of FA, Numerical Control Machining Center, Chengdu Aircraft Industrial Corporation, this paper elaborates the position of workshop scheduling system in CAC-CIMS/FA. After analyzing present production situation of Numerical Control Machining Center and the latest research on Job-Shop, it discusses the organization form of workshop production and specific scheduling algorithm, and points out that the system is developed under the architecture of Client/Server pattern of FA ,and it integrates and shares information with other FA subsystem. Therefore, on the basis of the above, it applies RDBMS to manage integrated information. Then, the workshop scheduling system was developed and realized in Client/Server pattern. Finally, the future development of the system was discussed.All the work done shows that the system can meet the need of workshop job scheduling of current stage, and may establish foundation for the development of the system in the future.
