In developing process for competitive commercial refrigerator/ air-conditioning system products, practical whole system integration method is very important to realize a compact product with high cost performance. These products are characterized by hierarchical architecture type module product systems. This paper proposes a practical lean development method which combines 1D and 3D-CAE analysis with human decision making process. A Model-based development method using product base platform is also proposed for realizing a practical product family series development. Finally, the effectiveness of this method is demonstrated quantitatively by applying to an energy saving type household refrigerator.
