Research On Theory And Method Of Green Design In Mass Customization Mode

With enterprise's production mode shifting from Mass Production to Mass Customization (MC), product design has been shifted from single product design to fast customized design based on product platform and product family. The present paper researched and discussed thoroughly on the construction of green design product information model under MC mode, green product customer requirements analysis and shifting, green design oriented product family planning method, product configuration based green product design and other related methods of green design in MC mode.In accordance with characteristics of each step in design process, on the foundation of analyzing product green design information requirements, a green product abstract depiction method based on inheritance was put forward, a green design product information model frame based on inheritance relationship under MC mode was built up, and green product design process supported by the information model was researched.Based on fundamental structure of green product customer static requirements template, a green design oriented dynamic customer requirements template was constructed, standardized depiction of customer requirements was realized. Ameliorated Quality Function Deployment for Environment (QFDE) method was adopted to realize the shifting from original customer requirements to product configuration information parameter. Green design of automatic soybean milk maker was used to exemplify this method.A definition of green product family was given and construction method of green product family was put forward. Conjoint analysis and systematic clustering methods were used to realize subdivision of green product customer group. Product family inner structural unit's green performance was quantified and analyzed from the four aspects of disassembly performance, recycle performance, environmental influence and economic performance. Fuzzy clustering method was used to categorize product family structural unit examples and a green design oriented product family planning method was built up. Product family planning of automatic soybean milk maker was used to validate and analyze this method.Integrating characteristics of product green design, a green design theoretical frame based on product configuration was built up. Green product configuration model building method and related algorithm based on three mainstream configuration methods (Constraint Satisfaction Problem, Case Based Reasoning and Optimized Configuration) were given. Assessment indicator system frame of configuration results were built up. Related method of assessing configuration results was given.Based the four theoretical methods mentioned above, a green design software system EAGDS for household appliance product under MC mode was developed. The present system was used in the green design of a household appliance manufacturer's refrigerator product. Theoretical method put forward in the present paper was validated in practical production.
