TOPSIS implementation in Python (Command Line Tool)

TOPSIS Implementation in Python

This project provides a command-line implementation of the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method using Python.
It allows ranking of alternatives based on multiple criteria, weights, and impacts.

---

What is TOPSIS?

TOPSIS is a multi-criteria decision-making (MCDM) technique used to rank alternatives by comparing their distances from an ideal best and an ideal worst solution.

The best alternative:

• Has the shortest distance from the ideal best
• Has the farthest distance from the ideal worst
