Research On A Closed-loop Management Method Of Manufacturing Inspection Based On PLM

With the rapid development of science and technology, the management level of companies, especially in designing and purchasing phases of the product lifecycle, has been improved with several informationization tools, such as PDM, ERP, CAPP, SCM, CRM, and so on. However, the informationization level of manufacturing inspection is not good enough. The CAQ system which could gather and analyze the data from workshops has been implemented by some companies, but it couldn't match with the deep needs of their business and the ISO 9001 standards. So, based on the PLM platform, a closed-loop management method of manufacturing inspection is presented.At first, an unified inspection data model and some work views faced to different phases are built based on the object-oriented method, which could store and show all of the static and dynamic data referred to the manufacturing inspection process more completely and scientifically.Secondly, an inspection workflow model is built based on extensional unified modeling language activity diagrams. And in order to improve inspection efficiency, standardize work process and keep information traceable, a management method of workflow driven manufacturing inspection is presented.What's more, a failure case knowledge library and an integrated inquiry tactic is presented based on CBR methodology. Then, the computer-aided FMEA, which is used to analyze the potential quality risks, could work more efficiently and intelligently.In the end, the solution of this paper is developed as a function module on PLM platform. And the feasibility is illustrated through the application in Huanghai Shipbuilding Company.
