Abstract: The product warranty involved in many fields, the interactions among technology, manufacturing cost and warranty cost were not taken into consideration in the design phase due to noneffective information communication channel. To deal with this problem, the feature mapping technology was introduced, and a cost optimization model based on feature mapping theory was established. Through using Analytic Network Process (ANP) and Genetic Algorithm (GA) to select rational manufacturing parameters, the optimization for manufacturing cost and warranty cost was realized. Application research was also conducted, and its promising future was revealed.
