Research On Functional Model In Green Design

While the development of the industry,especially manufacturing industry makesenormous change of human society,it also produces the problem of environmentdeterioration,energy and resource exhausting．It's well known now that green designhas become the key technology to sustainable development of manufacturingindustry．This dissertation researches on functional model system of conceptual design ingreen design．It mainly concentrates on the following items:1．By comparing with functional models in conventional design,and followingprinciples and requirements of green design,the structure of functional model systemin green design is constructed to establish functional model,including:functiondecomposition and function evaluation,methods to achieve function solutions,database and knowledge base involved．2．According to green design criteria,Functions in green design are decomposedby adopting function decomposition model based on quotient space．This functiondecomposition model is studied in disassembly oriented product recycling design ofgreen design．3．After establishment of functional model,axiomatic design method andfunction-failure design method(FFDM) are used to achieve function solutions．Thesetwo methods combined with green design criteria are studied by applying them inexamples of design．4．In this system data base and knowledge base are involved,mainly includinggreen design data base and function failure knowledge base．The structure of greendesign data base and function failure knowledge base is designed．...
