| The manufacturing execution system (MES), which is located between the project control system on upper level and the industrial control system on bottom level, is the management information system designed for workshop level. The manufacturing execution system, just like a bridge set up between the project control level and industrial control level, has joined these two levels together and ensured information to be transmitted throughout the whole enterprise in a smooth and integrated way. Due to various reasons, for a long time the degree of automation for the unit manufacturing resource management is fairly low, which has relatively obstructed unit automation progress. Therefore, It has become an important research topic in the field of manufacturing system that how to better manage the unit manufacturing resource, raise the degree of production automation, heighten the production efficiency and level of resources utilization, and lower production cost.The article is focused on analyzing function, performance and interface requirements of the resource management of MES. Based on requirement analysis, the writer has analyzed the dynamic relation between resource management system and production planning management system by establishing function module and information module for the system via the methods of IDEF0 and IDEF1X. The major function modules for this system are: cutting tools management, measuring tools management, work clothes management, materials management, equipments management, personnel management. In this system the requirements for trans-departmental information sharing can be satisfied and the functions such as inquiry, browsing, increase, deletion and revision to the related module are also available.This system has used the Web frame which is very popular nowadays, and adopted ASP as developing tool and selected Access2000 as its database management system. This system is provided with characteristics such as friendly user interface, easy operation and strong usability, etc. Through application of the unit resource management system, the scientific style and standardization and IT application for the workshop resource management can be realized. Furthermore, the production efficiency and level of resources utilization in the workshop has been raised and the operating cost lowered accordingly. Hence, the manufacturing resource management in mechanical production workshop has reached a higher level, which is of great practical significance and application value. |
