Below the sample example of the Intuitionistic Fuzzy EDAS method application is presented. More examples of package functionalities can be found in Jupyter examples.

from pyifdm.methods import ifEDAS
from pyifdm.helpers import rank
import numpy as np

if __name__ == '__main__':
    matrix = np.array([
        [[0.4745, 0.5255], [0.4752, 0.5248], [0.2981, 0.7019], [0.4374, 0.5627]],
        [[0.5346, 0.4654], [0.5532, 0.4468], [0.6300, 0.3700], [0.5901, 0.4099]],
        [[0.4324, 0.5676], [0.4030, 0.5970], [0.4298, 0.5702], [0.4361, 0.5639]],
        [[0.5235, 0.4765], [0.4808, 0.5192], [0.5667, 0.4333], [0.2913, 0.7087]],
        [[0.4168, 0.5832], [0.4923, 0.5077], [0.4732, 0.5268], [0.4477, 0.5523]]
    ])

    weights = np.array([0.2, 0.3, 0.15, 0.35])

    types = np.array([1, -1, 1, 1])

    if_edas = ifEDAS()
    pref = if_edas(matrix, weights, types)

    print(f'IF-EDAS preferences: {pref}')
    print(f'IF-EDAS ranking: {rank(pref)}')
