Topsis-Chahat-102303831 1.0.1

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.
