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:

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 0.71 6.7 42.1 12.59
M2 0.8 0.83 7 31.7 10.11
M3 0.7 0.62 4.8 46.7 13.23
M4 0.9 0.61 6.4 42.4 12.55
M5 0.9 0.88 3.6 62.2 16.91
M6 0.9 0.77 6.5 51.5 14.91
M7 0.9 0.44 5.3 48.9 13.83
M8 0.9 0.86 3.4 37 10.55

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.
