Package for Multi-Criteria Decision Analysis with distance-based TOPSIS method
Project description
distance-metrics-for-mcda
Python 3 library for Multi-Criteria Decision Analysis based on distance metrics. The documentation is provided here
Installation
pip install distance-metrics-mcda
Methods
This is Python 3 library providing package distance_metrics_mcda
that includes metrics that can measure alternatives distance from
reference solutions in multi-criteria decision analysis. This library contains module weighting_methods
with the following distance metrics:
- Euclidean distance
euclidean
- Manhattan (Taxicab) distance
manhattan
- Hausdorff distance
hausdorff
- Correlation distance
correlation
- Chebyshev distance
chebyshev
- Standardized euclidean distance
std_euclidean
- Cosine distance
cosine
- Cosine similarity measure
csm
- Squared Euclidean distance
squared_euclidean
- Sorensen or Bray-Curtis distance
bray_curtis
- Canberra distance

- Lorentzian distance
lorentzian
- Jaccard distance
jaccard
- Dice distance
dice
- Bhattacharyya distance
bhattacharyya
- Hellinger distance

- Matusita distance
matusita
- Squared-chord distance
squared_chord
- Pearson chi-square distance
pearson_chi_square
- Squared chi-square distance
squared_chi_square
The library also provides other methods necessary for multi-criteria decision analysis, which are as follows: The TOPSIS method for
multi-criteria decision analysis TOPSIS in module mcda_methods
. The TOPSIS method is based on measuring the distance of alternatives from
Positive Ideal Solution and Negative Ideal Solution using distance_metrics
mentioned above.
Normalization techniques:
