Intuitionistic Fuzzy MABAC

Method object

class pyifdm.methods.if_mabac.ifMABAC(normalization=<function swap_normalization>, distance=<function luo_distance>, score=<function liu_wang_score>, p=2.25, g=0.88)[source]

Bases: object

__call__(matrix, weights, types)[source]

Calculates the alternatives preferences

Parameters:

  • matrix (ndarray) – Decision matrix / alternatives data. Alternatives are in rows and Criteria are in columns.

  • weights (ndarray) – Vector of criteria weights in a crisp or Intuitionistic Fuzzy form

  • types (ndarray) – Types of criteria, 1 profit, -1 cost

Returns:

Preference calculated for alternatives. Greater values are placed higher in ranking

Return type:

ndarray

__init__(normalization=<function swap_normalization>, distance=<function luo_distance>, score=<function liu_wang_score>, p=2.25, g=0.88)[source]

Create Intuitionistic Fuzzy MAIRCA method object with normalization and score functions

Parameters:

  • normalization (callable, default=swap_normalization) – Function used to normalize the decision matrix

  • distance (callable, default=lou_distance) – Function used to calculate distance between two IFS

  • score (callable, default=liu_wang_score) – Function used to calculate crisp score of IFS

  • p (float, default=2.25) – Adjust parameter for distance calculation

  • g (float, default=0.88) – Adjust parameter for distance calculation

rank()[source]

Calculates the alternatives ranking based on the obtained preferences

Returns:

Ranking of alternatives

Return type:

ndarray
