Research On Total Quality Management System Modeling And Its Implementation Techniques For Product Life Cycle

The boundary of the modern enterprise organization is fuzzy and dynamic. Therefore,the modern quality management is faced with new challenges.Product lifecycle across organizational boundaries,links all taches of the supply chain,and carries a variety of business information and knowledge.Sponsored by the National High Technology Research and Development Program of China,the National Natural Science Fund of China and the Provincial Natural Science Fund of Zhejiang,TQM system modeling at the core of process and system developing are studied in this dissertation,which is surrounded the theme of product lifecycle.Chapter one introduces the background of research,surveys the current research situation of quality management system,and summarizes the development trends and hot spots of quality management system,which leads to this dissertation research contents.The research content includes product lifecycle total quality management system modeling at the core of process and its key techniques.Chapter two illustrates the ideas and basic principles of Product Life Cycle Total Quality Management(PLCTQM),establishes the basic architecture which consists of the product life cycle dimension,quality activities dimension and process organization dimension.Considering of the characteristics of modern enterprise's quality management and based on a comparative study of various modeling methods,a multi-layer and multi-view integrated process modeling method of product life cycle total quality management is put forward.In chapter three,the integrated modeling architecture of PLCTQM is studied on the multi-view expression,multi-level decomposition,multi-dimensional unwinding, the application of modeling methods and unified description under the guidance of the PLCTQM ideas and system framework.And an integrated modeling architecture is established,which process model is as the core,quality plan,quality control and quality improvement as the main content,the management of product,order,resources and quality characteristics as the main line,role and dynamic deploying as the process organization style,and extension theory as the model unified description.In chapter four,the quality transferring and mapping model is established.The basic elements such as customer demand,product quality and process quality etc.are defined,and theirs natures are described by introduction of extension theory.The quality transferring and mapping is studied from customer demand domain to product quality domain,and to process quality domain.The relationship of mapping as well as the degree of "qualitative change" or "quantitative change" can be described by extension transform,extension set,correlation function,extension entropy and so on. Therefore,the analysis methods of quality transferring and mapping are established. And a case of quality mapping is studied.The quality characteristics view is described by the Goal-Question-Method-Metric(G-Q-M-M) chain and extension theory also in this chapter.In chapter five,the computer realization of PLCTQM model and the key techniques related are studied.First,expanded activity node diagram as visual modeling tools applied to process modeling is researched.Then,introduces XPDL,and extends its semantic and attributes,as the unified description language for the information description of PLCTQM process model.Then,the concept of integrated activity cell is put forward,and its model is set up,which can ensure the effective integration of information and guarantee the quality information traceable and information structure extensible.Then,the approach of quality problem-driven is studied,and the quality knowledge acquisition model and quality fault diagnostic model is proposed,which makes the quality traceable and quality problem solvable become feasible.At last,the evaluation system of process model is set up,the optimization evaluation method of uncertainty power and uncertainty coefficient is put forward as the process model evaluating and quality evaluating,which can provide an important evidence for process improvement,process optimization and process reengineering.In chapter six,PLCTQMS system realization and application research is carried on.The transform of matter-element model and UML model is studied,and how to express matter-element model by OOP is also discussed.Based on the analysis of system requirement,the function modules and the general framework of PLCTQMS are planed,and the prototype of PLCTQMS is developed.Empirical application research is conducted after system finished.An Advanced Product Quality Plan(APQP) template is created for beating manufacturing enterprise's Total Quality Management. An empirical research of process model is made by collecting data from specific bearing enterprise,which verifies the effectiveness of system modeling and the practicality of system.In chapter seven,all research and innovation in this dissertation is summed up and the future research is prospected.
