Intuitionistic fuzzy analytical network process models for maritime supply chain

The aim of this study is to introduce three models along with four methods for intuitionistic fuzzy analytical network process (IFANP) and discuss the conceptual framework of process management for maritime supply chain. For the first time, in this study, centric consistency index is employed for all individual and aggregated judgment matrices of both membership and non membership functions together or separately. Secondly, consistency prioritization for each expert is implemented for all aggregated judgment matrices. Chang's extent analysis method and Gaussian approximation for IFANP method are firstly employed to IFANP. A comparison between the conventional version and proposed models of IFANP is provided. Process optimization for maritime industry is conducted by considering several perspectives including financial, technical, operational and safety concerns. (C) 2020 Elsevier B.V. All rights reserved.
