Abstract:

With the rapid development of modern technology and information, there are many complex multi-attribute decision-making problems with overlapping grey areas and ambiguities, and the decision attributes often have mutual interaction effects. To address the mixed multi-attribute decision-making problem with interaction effects between attributes, and a mixture of precise numbers, interval grey numbers, intuitionistic fuzzy numbers, hesitant fuzzy numbers, and linguistic variables, a mixed information grey relational decision-making method based on 2-additive Choquet integral is proposed.The specific research process as follows (1) First, the mixed information decision matrix R˜=r˜ijm×n is defined, and the mixed information grey relational coefficient ηij is constructed. (2) Then, the 2-additive Choquet integral operator is introduced to nonlinearly aggregate the grey relational coefficients of different attributes and construct the mixed information grey relational degree based on 2-additive Choquet integral, which can be expressed as ηi=j=1nIjηij-12cj,ckCIjkηij-ηik. Ijk indicates the interaction index between attribute j and attribute k. (3) To objectively determine the interaction indices between attributes, a mixed information grey relational multi-objective nonlinear optimization model is established, and the whale intelligence algorithm is used to solve the parameters. (4) Subsequently, a novel grey relational decision-making method with mixed information based on 2-additive Choquet integral is constructed, and specific algorithm steps are given.

Key words: grey relational decision-making, mixed information, interaction, 2-additive Choquet integral, whale optimization algorithm
