Abstract:

There are many factors involved in the quality of the gasassisted product. By the analysis of the special features of the gasassisted injection molding process, with the help of the orthogonal design of experiment, a fuzzy multiobject optimal decisionmaking model was built based on the theory of fuzzy mathematics and the programming method. A case study showed that the built model is effective to select quickly and correctly the optimized gasassisted.

Key words: material synthesis and processing technology, gasassisted product, quality optimization, multiobject, fuzzy decisionmaking
