P roduct family design is research focus at present and also is the core technolog y of DFMC (design for mass customization). Firstly, this paper explores the fund amental issues of product family, such as concepts of modularity, commonality/di versity, product platform and product family architecture etc. We compare the te rminology between product family and object-oriented approach in the next step. Thirdly, this paper puts forwards one product family design methodology based o n product platform and under different phase of product life cycle constrains, f or example, functional, assembly and service etc. At the end section of this pap er, we applied, the object-oriented approach in above mentioned product family design methodology to realize the design process.

Here, several examples of Java programs are presented. These examples show some major features that Java language provides, such as multi-thread, exception handling, network application writing, and the usage of Java applets. This article also shows some ways of setting up a Java language programming environment. All these examples are correct and ready to run.展开更多
