Research Of Enterprise Information Integrated System (EIIS) Of Electrical Equipment Industry

According to the civil situation, it is the trend for the manufacturing in China to rebuild and upgrade current pattern of manufacturing with modern information technology. The theory of Enterprise Information Integrated System (EIIS) emerges as the times require, which makes the best use of interior and exterior resources of these companies. Electrical equipment industry is a typical discrete manufacturing, whose design and manufacture are based on order form , and whose distinct characteristic on production is item-based management. So, electrical equipment industry EIIS should satisfy especial industrial requirement and achieve cooperation between various application subsystems, which is based on information share. The EIIS should achieve business application integration.This paper gives particular research on integrated framework of EIIS and its keyproblem--business integration between ERP and PDM. The highlights and maincontributions of the paper include:(1) This paper presents TiEIIS framework which is built on a platform and is based upon ERP. Traditional integration structure based on ERP is realizable but poor in expansibility. Another integration structure based on platforms has powerful function and expansibility, but its implement cost is exorbitant. The TiEIIS framework presented in this paper keeps the two structures' characteristics and complements their deficiency, which achieves mutual operation between application subsystems with different functions.(2) The key problems about the integration between ERP and PDM are solved in this paper. The file uses WBS (Work Breakdown Structure) which comes from Industry Engineering (IE) for reference, then it presents a project about MPS (Master Production Schedule) management which is based on WBS. This paper also introduces vaporware technology, and presents arithmetic to unite BOM after parallel design. Generally, because of the business integration between ERP and PDM, interrelated works of all designers will be involved in the whole management system synchronously, and the quality of electrical equipment industry's whole lifecycle will be improved.
