This book focuses on the development of multi-variant products using modular product structures and thus addresses the reduction of complexity from a product development perspective. These modular product structures allow for a greater variety of demand with a smaller, internal variety of components and processes. As a supplement to the common product development methodology, the necessary basics of modularity and variant diversity as well as the corresponding methods are presented comprehensively. The book thus summarizes the current state of science as well as the research activities of the...
