This paper presents a multi-criteria decision making (MCDM) for turning process. An experimental process was performed according to the sequence of matrix using Taguchi method with nine experiments. The parameters including workpiece speed, feed rate, depth cut, and nose radius were selected as input variables. At each experiment, three cutting force components that measured in directions X, Y,...

abstract— in this paper, a new extended method of multi criteria decision making based on fuzzy-topsis theory is introduced. fuzzy mcdm algorithm for determining the best choice among all possible choices when the data are fuzzy is also presented. using a new index leads to procedure for choosing fuzzy ideal and negative ideal solutions directly from the fuzzy data observed alternatives.in this...
