Mass customization is a new manufacturing concept.Because product cost and over 80 percent product characteristic is decided by product design phase.design for mass customization is so important about mass customization.Many scholars of countries have devoted to researching mass customization about the base concept.the key method,and technology such as product family design and modular design,and so on.Based on summarizing the correlative literatures and analysing the problems in current research systematically.the base concept.key technique and methods of design for mass customization are studied as follows:First.system info of design for mass customization is studied and about which some concepts are discussed in detail widely from module.customization parameter.platform parameter.product platform to product family.Design process of design for mass customization is put forward based on comparision between design processes of conventional single product design and modular serialization design.Second.the method of product family programming of design for mass customization is studied.There are three levels of problems which are taken into account as follows.ltem A.lateral direction module level.For re-design,based on the rule of function independence.structure integrity and variety of cumtom requirements.a correlative matrix of all information of parts is set up for the auto module partition.An improved method of computer-aided fuzzy clustering which named conjunction row by row is advanced for the algorithm of module partition.For creative design,a concept of generalized directed graph is advanced to express the function structure.Function module can be partitioned automatically based on gerneralized directed graph.Item B,cases of module.The strategy of product re-engineering is studied.A series of algorithm of product re-engineering is put forward based on fuzzy clustering about product spectrum,module interface and part configuration,and theredundance of products,modules and parts is removed and the interface paramters are normalized.A concept named delayed module is put forward and then the strategy of module delaying and product customization is studied based on delayed module.ltem C,product series level.Amath model of product series programming is put forward based on standard numerical system and programming strategy of platform parameter and customization parameter is studied.then a optimization model based on generalized optimization and module combination is set up to decided the value of platform parameters.Product platform of enterprise can be set up by product family programming.Third,method of product family modelling of design for mass customization is studied.Product information model is set up based on product property classified definition and flexible classification code.which mainly describe parts information themself. Product family meta model, noumenon model and variant model are put forward based on conjunctive normal form.They are hiberarchy models which can describe the hiberarchy relations between module and part.part and property.and also can realize product serialization and modularization modelling.A method of representation of assembly model of product family is put forward based on generalized non-directed graph.The strategy of closed loop solution of assembly constraint network is discussed.and then representation of assembly relation classification is studied.The assembly model of product family mainly describes constraint and transmission relation of assembly design parameter of different assembly unit.Modelling method of product family configuration model is discussed based on rule of "IF-THEN",which mainly to solve the representation of configuration constraint when building variant model.Forth.architecture of generalized supported platform of design for mass customization(GSP_DFMC abbreviated rearwards) is discussed and GSP_DFMC is elementarily realized based on WEB.Characters of different type of design for mass customization is discussed including lateral direction customizatio...
