A variable weight profit vector is proposed, which punishes the serious defects and rewards the slight ones. The optimization of injection mold proceeds as follows. First, the defects chosen as criteria for moldability evaluation are expressed as triangular fuzzy numbers according to their seriousness predicted by puteraided flow analysis and the initial weights of all criteria are assigned utilizing the analytic hierarchy process. Secondly, the varied weight of every criterion is calculated on the basis of the variable weight profit vector and then the fuzzy evaluation matrix is generated. Finally,the moldability indices of various mold schemes are obtained with the technique for order performance by similarity to ideal solution (TOPSIS), which ranks all the alternative mold schemes according to their moldability indices obtained by calculating the distances to both fuzzy seriousdefect ideal solution and fuzzy slightdefect ideal solution. The mold scheme with the biggest moldability index is regarded as the best one. A case study on the optimization of mold scheme proves that the proposed approach is valid, feasible, andsuperior to the others because of its capability in modeling the dynamic fuzzydecisionmaking logic of human experts.1. IntroductionInjection molding is one of the most widely used processes for manufacturing plastic product because of its mass production capacity and relatively low cost of each part. The major cost with an injectionmolded part lies in the mold design, which is greatly dependent on the decisions made by designers in the test runs and greatly influenced the final quality of plastic product as well as the injection molding cycle. Thus, it is important to integrate moldability evaluation with mold design early in the product development process for the purpose of achieving low product costs, low cycle times and high product quality. Computeraided flow analysis with engineering software such as MPI (moldflow plastic insight) is now widely used to predict the injection molding results of given mold scheme and to optimize the mold design, mostwork simply evaluating the moldability of mold schemes from the quantitative analysis of certain product defects or some physical parameters during injection molding (Kabanemi et al., 2002。 Courbebaisse and Garcia, 2002。 Alam and Kamal, 2005。 Sanchez et al., 2006。 Yen et al., 2006。 Henz et al., 2007).
