Abstract

All stages in product total lifecycle are a correlative whole which contains the whole closed loop process including
acquisition of users!? requirements, acquisition of custom-built product and after service. he traditional modular design
takes the modular and function analysis as its main characteristics. This article puts forward the method of modular design based on the product overall lifecycle which is the modular design based on the function partition of the modules to fulfill the demands of product development. This method is validated and analyzed through the example of the doubling machine in the article.
