A Comparative Study on Multi-Criteria Decision-Making in Dressing Process for Internal Grinding

Abstract

The MCDM problem is very important and often encountered in life and in engineering as it is used to determine the best solution among various possible alternatives. In this paper, the results of the MCDM problem in the dressing process for internal grinding are presented. To perform this work, an experiment with six input parameters, including the depth and the time of fine dressing, the depth and the time of coarse dressing, non-feeding dressing, and dressing feed rate, was conducted. The experiment was designed according to the Taguchi method with the use of L16 orthogonal arrays. In addition, TOPSIS, MARCOS, EAMR and MAIRCA methods were selected for the MCDM to obtain the minimum SR and the maximum MRR simultaneously. In addition, the weight determination for criteria was implemented by MEREC and entropy methods. From the results, the best solution to the multi-criteria problem for the dressing process in internal grinding has been proposed.

Application of topsis, mairca and EAMR methods for multi-criteria decision making in cubic boron nitride grinding

“…The application of the EAMR method for MCDM is carried out according to the following steps: Set up the decision matrix according to formula (15) with the note that k = 1 because there is only one result set. Determine the mean of the alternatives for each criterion according to (16) with the note that since k = 1, x x ij ij = . Next, determine the weights for the criteria.…”

“…TOPSIS and MAIRCA methods have been reported to be quite suitable for MCDM problems when CBN grinding on CNC machines. Specifically, these two methods have 11/18 options ranked the same (options 1, 6, 7, 10, 11, 12, 13, 14, 16, 17, and 18) when the weight calculation using the MEREC method and 8/18 options rank the same ( Options 4,5,10,11,12,13,16,17,and 18) when using the Entropy method. Meanwhile, the EAMR method has only the best solution (option 12) similar to other methods.…”
