A Python package for handling problems of Multiple Criteria Decision Making(MCDM) for a given dataset.

Topsis-Nipun-102003674

Topsis-Nipun-102003674 is a Python package for dealing with Multiple Criteria Decision Making(MCDM) problems by using Technique for Order of Preference by Similarity to Ideal Solution(TOPSIS). Topsis is a method of compensatory aggregation that compares a set of alternatives, normalising scores for each criterion and calculating the geometric distance between each alternative and the ideal alternative, which is the best score in each criterion.

Installation
