Fuzzy logic, desirability function, Taguchi method, multiresponse, and face milling


The Taguchi method is widely used to find an optimum setting of manufacturing process parameters. This paper is concerned with multi-response optimisation problems in the Taguchi method. For the same purpose, desirability functions have been used in the statistical literature. However, it should be addressed that measuring desirability has a vague aspect in nature. This paper proposes a novel method for the multi-response optimisation by embedding desirability functions onto fuzzy logic. The proposed approach is illustrated by example data of a face milling operation.
