Erp System Modeling Analysis And Research

At present, the traditional and structured modeling method in ERP (Enterprise Resource Planning) system development field in China can not satisfy user's demand that changes with each passing day and the uncertainty of software demand changes, have caused the failure of software development. At the same time all types of object-oriented software modeling method will not combine business engineering field with software engineering field effectively. For solving the problems that have mentioned, on the bases that UML (Unified Modeling Language) has the characteristic of striding across both business engineering field and software engineering field this paper has put forward the solving schema that use object-oriented method to establish model for large scale information system.Firstly, by the description of the actuality of enterprise that is informative, the author has summarized the problems of implementing ERP system in enterprise, and pointed out the importance of modeling for ERP system. On the bases of comparing the structured modeling method and the object-oriented modeling method, the author has put forward the advantage of establishing ERP systematic model by using the object-oriented techniques and has established ERP system modeling frame model which has realized the reflection of domain business modek requirements modeh systematic analysis and design model, implementation model on the foundation of Rational unified process(RUP) of UML and CIM-OSA(Computer Integrated Manufacturing-Open System Architecture). That offered feasible solving schema of systematic software engineering for the successful realization of ERP.This paper has used the established ERP system modeling frame model to carry out demonstration research for ERP system of process type enterprise (some steel enterprise). The author has put forward the modeling method and mechanism for process type enterprise by using of UML and ERP system modeling frame model, analyzed and designed the business model, requirements model, systematic analysis and design model, implementation model of sale subordinate system in ERP system of enterprise. This has important realistic meaning for analyzing and implementing ERP system for enterprise.This accomplishment has important meaning for the searching of business as...
