Project Description

TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) is a multi-criteria decision-making (MCDM) method used to rank alternatives based on their distance from an ideal best and an ideal worst solution.

This Python package provides an easy-to-use command-line implementation of the TOPSIS algorithm. It allows users to input a dataset along with weights and impacts and produces a ranked output based on TOPSIS scores.
