Abstract
Manufacturing Execution System (MES) is a job-shop production oriented management information system and the bridge between production plan management layer and job-shop control layer in an enterprise. Job-shop scheduling is the core module of MES, which direct affects the efficiency of production and management in the enterprise. According to the characteristics of discrete production management, a job-shop production scheduling system is presented that adapts to multi-variety small-batch production. A MES architecture for dynamic discrete production and its core modules are presented. Then, dynamic job-shop production scheduling problem is visually modeled and simulated based on Witness to realize optimal resource deployment.
