Pathalavathi Bhaskar, Sarat Kumar Sahoo
Abstract
The most essential goal of the optimization process is to minimize the cost and maximize the profit.In the case of industrial decision-making, optimization plays a major role.In the optimization process, the main target is to maximize 1 or some process parameters by keeping other parameters within constraints.Desirability function analysis (DFA), is a technique for the optimization of multiple response variables extensively used in the industry.DFA is based on the concept of the "quality" of the product or process having several quality characteristics.This method operates on the conditions which give the "most desirable" response values.In this review paper, the main concentration is on the optimization of a number of manufacturing processes which has been optimized by using DFA method.The previous review work by earlier researchers on the manufacturing process was not performed on such a large scale at a time on the DFA method by considering different processes.In the future, this review work can be worthwhile for the information at a single place for the succeeding researchers, in order to conclude their research work on the DFA technique.
