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 the shortest Euclidean distance from the ideal solution and greatest distance from the negative-ideal solution. More details can be found on Wikipedia.

How to use this package:

The TOPSIS-MAHESH-MANI-102297002 package can be run as shown in the following example:

In Command Prompt to run the code:

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

Explanation:

• Name: Identifies the alternatives.
• P1, P2, P3, P4, P5: Represents the performance values for each criterion.
• Topsis Score: The calculated TOPSIS score for each alternative.
• Rank: The ranking of each alternative based on the TOPSIS score.

Simply run the provided command in the Command Prompt, replacing the input data file name, weights, impacts, and result file name with your specific values. The output will be a new CSV file containing the results of the TOPSIS analysis.
