A Python package implementing TOPSIS technique.

Project description


What is TOPSIS

Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) originated in the 1980s as a multi-criteria decision making method. TOPSIS chooses the alternative of shortest Euclidean distance from the ideal solution, and greatest distance from the negative-ideal solution.

How to use this package:

TOPSIS-Chirag-101803366 can be run as in the following example:

In command prompt:

>> TOPSIS data.csv "1,1,2,1" "+,-,+,-" result.csv
