A Python package implementing TOPSIS for MCDM problems

## Project Description

Topsis-Chahat-102303831

For: Project-1 (UCS633)

Submitted by: Chahat

Roll No: 102303831

Topsis-Chahat-102303831 is a Python package for solving Multiple Criteria Decision Making (MCDM) problems using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS).

The package ranks alternatives based on their distance from the ideal best and ideal worst solutions.

Installation:

Install the package using pip:

pip install Topsis-Chahat-102303831

Usage

Provide the input file name, followed by the weights vector, impacts vector, and the output file name.

topsis data.xlsx "1,1,1,1,1" "+,+,+,+,+" output.csv

Vectors can also be entered without double quotes:

topsis data.xlsx 1,1,1,1,1 +,+,+,+,+ output.csv

If the vectors contain spaces, they must be enclosed in double quotes.

To view help:

topsis /h
