Abstract
This chapter presents a three-phase methodology, which is proposed for the development of complex products using the modularity concept. The proposed methodology matches the criteria set by the design for functionality, assembly, and manufacture. A detailed discussion of needs analysis, quality function deployment, product requirement analysis, product/concept analysis, product physical analysis, product functional analysis, product/concept integration, identification of the Impact of system-level specifications on general functional requirements, similarity index, and optimization-based solution methodology for grouping components into modules is presented in this chapter. Finally, genetic algorithm-based solution methodology and algorithm-based solution methodology for grouping components into modules are described for understanding the presented concepts.
