Study On Production Scheduling System Of Manufacturing Workshop Based On MES

Production scheduling system is a comprehensive functional department and it's also the production command center of the enterprise because it controls and coordinates each process and tache of the production activities. In the production scheduling system of traditional manufacturing enterprise planning, controlling and scheduling can't realize the whole optimization. It also brings out many problems such as the plan layer is lack of the necessary current information during the process of scheduling and the controlling layer can not send the out-plan or windage information that may will take place or have taken place during production to the plan layer timely.MES can be defined as a management information system lies between the top layer of plan management system and the bottom layer of production controlling which set toward to the workshop. MES built the computer aiding workshop management information system aimed to manage the production task which can deal with problems mentioned above. This MIS on the one hand converts the plan information come from plan management system of the enterprise into the instruction and then send it to the production process controlling system, on the other hand it can acquire the current information from the spot production process controlling system and then send this to plan management system.Although MES possess these functions, studies on MES mainly focus on the theory. Considering on this situation, this task realized MES through developing the production scheduling system of first workshop of Shenyang Heavy Machine Manufacturing Corporation by using VB and Server 2000.This workshop production scheduling system based on MES mainly includes structure of the system; the function design; the choice of system developing surrounding, tool and system structure .The final display results include: basic information management module; production task plan management module;production scheduling management module; production process controlling module. By using this system it can disengage the production management personnel from burdensome handwork task. Using the intuitionistic of the computer view interface, the practice and controlling of the production plan may be increased also the time and of information sending error can be decreased. Thus enhances the competitive strength of the enterprise.The study on workshop production scheduling system based on MES in the paper involved the whole development process and also can do some matting to other study based on MES .
