An AHP method based design for manufacture for parts manufacturability evaluation

Qingming Fan, Hongjun Liu

In the light of growing global competition, organizations around the world today are constantly under pressure to produce high-quality products at an economical price. Design formanufacturability (DFM) requires product designers to simultaneously consider the manufacturing issues of a product along with the geometrical and design aspects. The integration of design andmanufacturing activities into one common engineering effort has been recognized as a key strategy for survival and growth. DFM requires product designers to simultaneously consider the manufacturing issues of a product along with the geometrical and design aspects. In this paper, partmanufacturabilitywas analyzed in detail.An analytic hierarchy process (AHP)method is introduced to assignweighting factors to features to reflect their functional importance. Results from the case studies show that the system is capable of generating sound manufacturability indices that could help product designers inmaking designs easier to manufacture
