Functional Evolution Process Modeling and Management for ConceptualProduct Design
Function modeling and evolution is a key stage in conceptual product design.To enablethe efficient functional evolution,the functional evolution process needs to be modeled and managedin a systematic way.Current PDM systems can effectively manage the final product data andinformation,but can not deal with documentation about the function design and related evolutionprocess.Therefore,a functional evolution process modeling management mechanism has beenproposed and a related computer aided system has been developed.Firstly,in an attempt to achieve ashared understanding of the functional evolution activities,a set of consistent and coherent definitionsof the functional evolution activities are deliberated and presented.Four basic pairs of functionevolution directions have been presented to describe what each specific function evolution designactivity entails,and the function structuring is circumscribed with defined causal function relationsand structural function relations.Then,a function evolution process model is introduced,aiming togive a support for obtaining an appropriate representation of information about (1) function versionwhich can reflect the phases of function evolution process,and (2) function evolution activities whichcompose the whole function evolution process.A framework for functional evolution processmanagement has been established,which can not only capture evolution of function objects,but alsorecord the designers functional design intent systematically.
