It extends MRP II to the Enterprise inner resource plan enclosing the remands of market. Its meaning is embodied by three levels-management ideology, software product and management system: it is a series of enterprise management system standards put forward by the famous computer technology consulation and evaluation corporation-Gartner Group Inc, it is, in fact, a supply chain oriented management ideology based on MRP II; it is a software product collegiating new information technology such as C/S, relational database, OOT, GUI, 4GL, net communication etc. Its soul is ERP; it is a enterprise resource management system integrating enterprise management ideology, business process, base data, human and material resources, computer hardware and software. In some sense, it is a standard to measure enterprise modernization, so it is rapidly accepted, and bring rich benefits to lots of enterprises. It can be forecast that ERP will be used widely in our country.In this paper, the author firstly analyzes the up-to-date theory of ERP and the relationship between ERP and supply chain, business process reengineer. ERP's core is SCM, it regards business process as a compact supply chain including supplier, manufacturing factory, sale net and customer etc. It carves up enterprise to several cooperating subsystems such as finance, market, manufacture, quality control, service, technology and competitor moniting. Modernization of enterprise management is the combo of modern management ideology and modern organization methods. ERP, the software embodying modern management ideology, must require the corresponding management organization, so it is necessary that uniting ERP and BPR.According to the above theories, the author designs and develops the ERP system of Henan Taihang vibrating machinery Co., LTD (THZD-ERP). This corporation is a tipcal dispersed manufacturing enterprise manufacturing vibrating machinery and electronic and environment protecting equipment. It is one of Chinese high technology research and develop plan 863/CIMS applying demonstrating enterprises. This project is a subproject of Chinese 863/CIMS applying demonstrating project, it is the second development of the former ERP system. According to the modern ERP design and actualization ideology andmethods, and based on the research of the former ERP system, the author designs the THZD-ERP, puts forwards the system flow chart. The author detailed designs the project of material, sale, and plan information, the project of product planing control information,furthermore, the author put forward the DFD of most modules. This project is based on the existing management system, but better than the system, it absorbed in the ERP's base kernel and logic, implement the former ERP system. This project is feasible in the development and run conditions, and can bring rich benefit for the enterprise.During the time of ERP's implement and maintenance, the author realized the defects of traditional ERP system such as complicated and hard-shelled structure, hard to do BPR, depended on organizing model and so on. So the author studies on the dynamic enterprise modeling(DEM) and component object modeling(COM), and explores the dynamic ERP system which is use DEM as theory direction and implement by COM. Firstly, we implement the function model using COM components, then, integrated the COM components by proper develop tools such as MS Visual Basic Delphi etc. according to the business process. We choose Delphi as the develop tool, the steps as the following:Analyze and confirm the business objects and their relationship-implement thebusiness objects by Delphi-uisng the Active X guide create business components-integrate business components and build the whole system.The implement of dynamic ERP system will make the manager and business analyzer can concentrate on the high level management and optima... |
