Research On Integrated Technology Of Design Quality Information And Development Of Prototype System

The view that design quality is the source of product quality has been gradually recognized by more and more enterprises.Then,more and more pervasive attention has been paid on product'design quality,meanwhile,much resource has been devoted to look for the effective approach to improve product'design quality.Paper summarizes four research approaches to improve design quality which are existed.However,these four approaches utterly based on the same hypothesis,which is that the information to guarantee and improve design quality is definite, the expression of information is unified and easy-understanding, collection and communication is easily realized.But as far as the current conditions is concerned,this hypothesis is hardly tenable.Without relative information's support,however advanced the methods to improve design quality which the above four approaches mentioned are, the implementation effect will not be as obvious as expected.Therefore,paper presents the research approach that design quality is guaranteed and improved from the aspect of information.The concrete research measures are as followed:expand the sources of design quality information by means of defining design quality information as the data which is beneficial to improving design quality;plan design quality information by the technology methods of information resource planning;build the integrated model of design quality information;organize and express design quality information with unified formal;provide relative information support for designers whoever he belongs to its enterprise or not by intellectively collecting and storing design quality information.Firstly,paper definitely defines the design quality information,points out the research range of design quality information,and then presents a research approach to guarantee design quality from the aspect of information by building integrated model of design quality information.Secondly,paper analysises the function and data demand of integrated model of design quality information by means of the technology method which information resource planning mentions,and then establishes the system structure of this model. Thirdly,paper makes an emphasis on the key technolodies,i.e. the technology for organizing and expressing design quality information based on XML;the technology for integrating design quality information based on Multi-agent system. Finally,paper introduces prototype system developing and realization and verifies it by an instance.
