Design and Implementation of a Real-Time Jobshop Scheduling System

In this paper, a data-based scheduling software system is presented for job-shops which operate in today’s highly dynamic and uncertain competitive manufacturing environments. To incorporate the dynamic or uncertainty elements into the scheduling process, special emphasis is put on the real-time, dynamic behavior of the manufacturing system. The requirements of the scheduling system is analysis, subsequently, the details of the system model and the main function modules are described and implemented. One key feature of the proposed system is that the scheduling decision is making basing on the production data in manufacturing processes, not only those historical data but also these real-time data. Another feather is that it could make detailed, short-term production scheduler, which integrated the functions of real-time production monitoring and control, as well as coordination of component supply. Problem of various sizes are used to test the performance of the proposed system, and satisfactory results have achieved.
