Component-based Cost Management Information Systems Research And Development

With the increasing competition of the market, product cost has become determinant for enterprises to survive and succeed in competitions. Enterprises have realized the importance to manage cost information with computer and already actualized cost information management system more or less. But how to manage the cost information accurately, how to present a platform for cost information management in integrated environment and how to avoid the repeated work in system development are problems faced by us. Therefore, the paper discusses and develops the component-based cost management information system for enterprises of research type in integrated environment on the basis of Southwestern Electron and Telecom Technology institution (SETT)'s ERP project.Firstly, the paper compares the difference between mass production and muti-type & small-batch production, enumerates a series of problems to be solved in actualizing management information system for enterprises of research type, presents the total design of the system with full consideration of the integration with other subsystems and establishes the function model and the information model of the system with IDEF modeling method.Secondly, the paper develops the system with simple component object model (COM) technology on the basis of the above design. The new system is developed on advanced C/S module, with Delphi 6.0 as the desktop tool in clients and Oracle 8.16 as the database management system in server.Finally, the paper discusses and analyses the result, presents the idea to improve the system.The eighth department of SETT has put into use the cost management information system and greatly increased the efficiency of cost management work.
