| To win in intense competition for enterprise, using ERP/MRPII is a necessary trend. Material Requirement Planning (MRP) is such kind of product management method based on computer technology. From the birth of MRP idea to now, many MRP systems have been developed, including abroad and domestic. But with the change of competition environment and development of production method, MRP system is required to have good maintenance.openness.scalable.currency and rapid response. Maintenance is required to meet the change with minimum expense. Openness is required MRP system to integrate with other MRP system easily. Currency is required MRP system to support all kinds of production methods. This paper researches this technology, which makes MRP system to meet all above requirements.This paper discusses how to meet above requirements from three aspects : modeling of MRP system,architecture of MRP system and development of MRP system. This MRP system is modeled with UML (Unified Modeling Language), in which the information and function is packed in objects. Because this MRP system can be modified rapidly in objects, it has good maintenance. This MRP system also uses distributed architecture. The logic part of program is deployed in the application server, which makes the MRP system have rapid response.openness and meet the requirement of group corporation. In the development of MRP system, the component technology is used. Because the function part is packed in components, which can be uninstalled or given away on basis of the requirement of corporation, this MRP system have good configuration. In addition, this MRP system absorbs the idea of JIT (Just In Time) and uses the JIT/KANBAN production method to support repetitive manufacturing.Through research, this paper puts forward valid technology to solve the problems of MRP system, and makes the new system to meet those requirements: good maintenance,openness,scalable.rapid response and the support of all kinds of production method. |
