Macro level product development using design for modularity

TLDR: In the proposed methodology the needs and product functional requirements are first established, and a clustering technique is used to integrate the basic components into design modules based on their similarity index.

Abstract: Modular design is an engineering methodology that will organize and structure a complex product, process or system into a set of distinct sub-systems and components that may be developed independently of each other and then assembled together. Modular design aims at identifying independent and standard units that could be used to create a variety of products. A structured methodology is proposed for identifying components that can be developed in parallel. In the proposed methodology the needs and product functional requirements are first established. The product is then decomposed based on its functional and physical characteristics. Next, a similarity index is introduced to measure the associativity between the basic components. Finally, a clustering technique is used to integrate the basic components into design modules based on their similarity index.
