In Mes Planning And Scheduling

Manufacturing Execution System (MES) is the tache of information integration of the Computer Integrated Manufacturing Systems, is the basic technical means for the enterprise to implement agile manufacturing and realization workshop production agile. Planning and scheduling are the key problem to make production more efficient, more flexible and more reliable in a workshop and it's becoming a key module of MES. Therefore, the planning and scheduling faced on MES is now a hot issue of many enterprises.In this paper we focused on the more varieties and small-batch processing features discrete manufacturing enterprises that have the rough task scheduling, a long life cycle of exception handling and a long waiting time for the work in process. To solve this problem we bring forward a planning and scheduling management method which can improve and optimize the current planning and scheduling works.First presented in the paper give a idea of template-based planning and scheduling management and the application of monthly production plan templates, batch production plan template, process-level detailed production plan template, dynamic scheduling application templates; and then discussed in detail the realization of using process-level production planning template to constitute work plan which based on batch production plan in planning and scheduling module. We also do many researches on the methods how to constitute process-level production planning based on Gantt chart and Ant Algorithm. Finally, give some dynamic scheduling strategy to deal with the abnormal in the actual production process.Based on above research, we developed a planning and scheduling management module for a country's large state-owned enterprises, and using software engineering ideas, based on the point of view of software design, analyzed the system structure and information modeling of planning and scheduling management module and design and implementation finally.
