The researchers aimed to develop a new method for creating products and their production systems together to solve industry challenges. They combined engineering tools with a logical design theory called axiomatic design in a coordinated design environment. Their work focused on improving product assembly. They found that while the original design theory was good for parts, it needed adjustments for multiple-part products and matching production processes. They suggested changes to the design theory to create a Manufacturing World divided into specific spaces for different processes and functions, facilitating product and production system development using the same approach. Industrial examples validated the methodology's effectiveness in integrating product design with production processes efficiently.
