What is TOPSIS

Technique for **Order **Preference by **Similarity to **Ideal Solution (TOPSIS) originated in the 1980s as a multi-criteria decision making method. TOPSIS chooses the alternative of shortest Euclidean distance from the ideal solution, and greatest distance from the negative-ideal solution. More details at wikipedia.

How to use this package:

Topsis-Yoshna-101903502 can be run as in the following example:

In Command Prompt

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

In Python IDLE:

import pandas as pd from topsis_py.topsis import topsis dataset = pd.read_csv('data.csv').values d = dataset[:,1:] w = [1,1,1,1] im = ["+" , "+" , "-" , "+" ] topsis(d,w,im,output.csv)

The rankings are displayed in the form of a table using a package 'tabulate', with the 1st rank offering us the best decision, and last rank offering the worst decision making, according to TOPSIS method.
