Research On Some Key Techniques For Small And Medium-Sized Manufacturing Enterprise In ERP Implementation

With the support from the item of State 863 High-Tech R&D Program of China (No.2003AA414045) and the major research project of Zhejiang manufacturing enterprise informationization engineering (2003C11010), based on the analysis and overview of related literature and research status quo in SMME-ERP implementation, this thesis is mainly concerned with several key enabling technology in ASC including SMME-ERP implement process model,implementation ability evaluation and software selection, implementation conflict and solution, implementation perforance evualuation. The thesis aims to provide theoretical and methodological guidance for SMME ERP implementation and to improve the efficiency and the rate of success. Six chapters are included in this dissertation.In chapter 1, Firstly, the history of development of ERP system in Chinese manufacturing enterprise and the state of arts of small and mediun manufacturing enterprises ERP system implementation was reviewed. Then, the focus will be on the analysis of the causes for the low rate of success in SMME-ERP implementation.Thirdly, the research of implementation capacity evaluation, selection of ERP, implementation process conflict and solution, implementation performance evaluation,implementation process control etc were summarized. On the base of these, this dissertation propose the research objective and main content.In chapter 2, on the basis of an analysis of the definition, connation and characteristics of SMME and ERP implement process management, the essence of the process management of SMME ERP implementation, that is, to make the contents and the process rationalized and to enhance the rate of success, are pointed out. Then, the process model of SMME ERP implementation is established. The process model is enterprise oriented to the total process of SMME ERP implementation. The implementation steps and guidelines in the process model are presented as two major phases including SMME informatization planning and SMME ERP implementation. These principal works and key techques in every phase .are also introduced in the model.In chapter 3, Firstly, A dendriform evaluation model is presented based on the analysis of the characteristics and principles of ERP application evaluation system. The model consists of five components, each of which has some sub-objects.It can make multi-level assement for ERP application with fuzzy mathematics. Secondly, the evaluation indexes are stated in detail in the the model, and some key issues are discussed, such as the process of the indexes values, the determination of the index weight and the calculation method. Thirdly, a software selection approach is developed for ERP of small and mediun-sized manufacturing enterprise. Based on grey relational theory, a evaluation process model for ERP selection is constructed and ERP selection evaluation architecture was designed by using Balanced Score card. According to benchmarking theory, referred series is given and based on the analytical hierarchy process technique; all the relative weights are calculated to select the best ERP software.In chapter 4, These conflict factors in ERP implementation of small mediun -sized eterprise were analysed and an ERP implementation process conflict model is construced.. After the ERP implementation networks was construced, combining these proposed temporal constraint networks rules with the method of graph theory were applied to converte it into temporal constraint networks. Then, those implemention conflicts and .the shortest time are solved by the consistency algorithm for temporal constraint networks. Then, these multi-duty conflict by the constrained resource is analyzed and based on the characters of small and mediun-sized manufacturing enterprise, a technique improved from facilitate critical method is proposed to solve the conflict and can maximize SMME.In chapter 5, Information quality is an part of information system success model and is impottant to evaluate ERP implementation performance .After information content, information quality connation, information characteristics and the problems of information quality existing in Chinese manufacturing enterprises are analyzed in SMME-ERP, a business process-based methodology is developed to form for information quality assessment and benchmarking and.a techque based on the rational of information difference is proposed to evaluate its information quality. In order to improve information quality, the quality control program of ERP implementation and its evaluation index system are given.Finally, under the small and medium-sized manufacturing enterprise erp congdition, a method based on statistical process control.was introduced to improve product quality caused by process control.In chapter 6, systematical summary is given, and future work is put forward.
