Based Tool Integrated Erp System Key Technology Research

Enterprise must have more effective means of management in the market economy environment, ERP software as a combinative result of advanced enterprise manage ideas and computer technology has became a power full tool for every manager to improve their manage level and enhance the competitive capability of the enterprise. But with the development of aggravation of enterprise's competition and computer technology, all sorts of drawbacks existed in ERP system display gradually. At first focus of contradiction concentrate on data communication impels ERP system progressively in the direction of data integration. The earlier contradiction focus on data share aspect, which impels ERP system develop from the integration of function module to the integration of data progressively. While the technology of data integration and share is constantly perfecting enterprise ERP systems, people find gradually that data integration does not solve all problems which have been brought by design every isolated function module respectively. For example, the way to use module of software with function model has brought the question of integration and share of algorithm and model, etc. In addition, because systematic limitations in the process of implement of ERP cause all sorts of question which impel researchers and enterprises to improve existing system as well as to begin the research and development work of new-type ERP system.Under above-mentioned backgrounds, this thesis puts forward the concept of ERP system based on the tool integration and then makes deeper research on several key technology issues involved in researching and developing. In this direction of model and algorithm integration the thesis has finished the following job:1. In order to build ERP system based on the tool integration andestablish the theoretical foundation of separating the model from corresponding algorithm, we carried on the scientific classification for various kinds of mathematics model and algorithm existed in every function module of ERP system.2. Basing the before work and the development of computer technology, the thesis has probed into model inputting and application technology in details, put forward the concept of model input pattern and inner model and solve the key skill in the model inputting and application technology.3. After theory analysis above, this paper provides several kinds of way that models are inputted into the computer. Finally we developed some part of codes with platform of Visual Basic 6.0 in order to prove the exactness of theory and method proposed.The main innovation of this paper is that: Divide the model and method of ERP into five big classes which contain planning technology, map and network technology, decision and countermeasure technology, stochastic operation technology and modern optimization technology. Research on the theoretical foundation and application of each class model existed in ERP system. More important point is that we has combined model input issue to propose the technique to solve the model input problem of ERP system based on the tool integration and has worked out the verification for the theory and method through some procedures. At the end of this article, we put forward the respect and direction which need to be improved and study afterwards.
