Application of Grey Based Taguchi Method in Optimization of Process Parameters- A Review

Over the years, optimization of process parameters of various engineering process has been the challenge for the researchers. Process outcomes depend upon the process parameters so optimization of process parameters is necessary. Single output problems can be solved by various conventional optimization methods but multi-objective optimization problems are critical to solve and hence to achieve optimal process parameters is a challenge. Taguchi method is a popular approach to optimize the process parameters of any process. But for multi-objective optimization, Grey based Taguchi method is utilized to achieve the optimal process parameters and ANOVA is used to validate the results. In this article, review of optimization of various processes using grey relational analysis is employed. It is found in this review article that grey relational analysis is the competent optimization approach to achieve the optimal process parameters.
