There are various attributes to determine the performance of a PTSC system and MADM is the simplest among all of them. This paper utilizes one of the attributes of MADM i.e. TOPSIS and explains the application of TOPSIS method using four different materials. Here it is shown that the best solution obtained by TOPSIS method is neither close to the positive ideal solution nor farthest from the negative ideal solution. The basic principle of TOPSIS is that the chosen alternative should have the shortest distance from the positive ideal solution and the longest distance from the negative ideal solution.
