A CLI tool for TOPSIS decision-making

TOPSIS CLI Tool

TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) is a multi-criteria decision-making method that helps evaluate and rank options based on their relative closeness to an ideal solution. This CLI tool provides a simple and efficient way to perform TOPSIS analysis directly from the command line.

Features

Supports weighted and impact-based decision-making. Reads input data from a CSV file. Outputs ranked results with scores in an easy-to-read CSV format. Lightweight and user-friendly command-line interface.

Installation

Install the package using pip:

pip install topsis-cli

Usage

Run the CLI tool with the following syntax:

topsis <input_file> <weights> <impacts> <output_file>

input_file: Path to the input CSV file containing decision matrix.

weights: Comma-separated list of weights for each criterion (e.g., 0.4,0.3,0.2,0.1).

impacts: Comma-separated list of impacts for each criterion, either + (positive) or - (negative) (e.g., +,+,-,+).

output_file: Path to save the output CSV file with scores and ranks.

Example

Input File (data.csv):

Name	Criterion 1	Criterion 2	Criterion 3	Criterion 4
Option A	250	16	12	5
Option B	200	18	8	3
Option C	300	14	10	4
Option D	275	15	9	2

Command:

topsis data.csv 0.4,0.3,0.2,0.1 +,+,-,+ results.csv

Output File (results.csv):

Name	Criterion 1	Criterion 2	Criterion 3	Criterion 4	Score	Rank
Option A	250	16	12	5	0.75	2
Option B	200	18	8	3	0.50	4
