Description: Evaluation of alternatives based on multiple criteria using TOPSIS method..
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.
How to install this package:
>> pip install TOPSIS-Pranav-102003432
In Command Prompt
>> topsis data.csv "1,1,1,1,1" "+,+,-,+,-" result.csv
Input file (data.csv)
The decision matrix should be constructed with each row representing a Model alternative, and each column representing a criterion like Accuracy, R2, Root Mean Squared Error, Correlation, and many more.
Model | P1 | P2 | P3 | P4 | P5 |
---|---|---|---|---|---|
M1 | 0.7 | 0.5 | 7 | 37 | 11.3 |
M2 | 0.8 | 0.6 | 7 | 46 | 13.4 |
M3 | 0.7 | 0.5 | 7 | 48 | 14 |
M4 | 0.9 | 0.8 | 7 | 44 | 13.2 |
M5 | 0.9 | 0.9 | 5 | 37 | 11.1 |
M6 | 0.9 | 0.6 | 3 | 67 | 18 |
M7 | 0.9 | 0.5 | 7 | 39 | 11.8 |
M8 | 0.9 | 0.9 | 5 | 46 | 13.2 |
Weights (weights
) is not already normalised will be normalised later in the code.
Information of benefit positive(+) or negative(-) impact criteria should be provided in impacts
.
