Multiple-Criteria Decision-Making Attributes Approach for Carbon-Reduction Construction in Small Islands

Abstract

Chiang, T., 2022. Multiple-criteria decision-making attributes approach for carbon-reduction construction in small islands. Journal of Coastal Research, 38(2), 310–318. Coconut Creek (Florida), ISSN 0749-0208. The group decision-making with dependent attributes problem (GDMDAP) is an increasingly important problem for small islands in the construction industry to achieve carbon-reduction and sustainability goals with a win-win vendor selection process. In this paper, an innovative approach that integrates the stochastic matrix and the VIseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method is applied to solve the GDMDAP. The 795 records from the 47 carbon-reduction projects in Kinmen, an island with zero carbon visions in Taiwan, are surveyed from 2014 to 2021. The 67% decision attributes in the case study are dependent based on the Spearman's rho test. The test verifies that decision-making is difficult to apply to the traditional multiple-criteria decision-making method for carbon-reduction projects. The analytic network process method is also difficult to estimate because of the range problem of ratio variable scale. Based on the stochastic matrix and modified linear normalization, a 0–100 scale decision matrix with dependent attributes is transferred to a 0–1 scale with less than a two times scores gap. The group VIKOR method is used to integrate the acceptable advantage and acceptable stability. The performances of the traditional ranking method and the proposed approach are compared with one of the 47 carbon-reduction projects. The results show the effectiveness and superiority of the proposed approach.
