Module-Based Model Change Planning in Consideration of Environmental Impact and Customer Satisfaction

Enhancing reusability and improving product functions can create a contradictory issue that must be solved for realizing the closed-loop manufacturing. This paper proposes a concept of module-based model change planning as a solution to this problem and discusses a method of identifying relationships between customer satisfaction and modules, which is a key to realizing this concept, based on conjoint analysis and QFD. The method is applied to copying machines as an illustrative example.
