An improved DEMATEL method for multigranular hesitant fuzzy linguistic environment

Abstract

The decision‐making trial and evaluation laboratory (DEMATEL) is widely recognized as an effective way to identify the key elements of a complex system and establish a causal relationship between the criteria. To extend the effective use of the DEMATEL method in multicriteria group decision making problems, we propose some improvements for traditional DEMATEL. The direct‐influence matrix is a pairwise comparison matrix of the influence level between criteria, which is the basis of the DEMATEL method. Instead of utilizing crisp numbers to assess the level of direct‐influence, each expert provides evaluation with hesitant fuzzy linguistic term sets (HFLTSs) based on an individual linguistic term set, that is, multigranular hesitant fuzzy linguistic term sets. To obtain a reasonable and satisfying collective DIM, we propose the expert weights model based on the similarity and entropy of HFLTSs and introduce the consensus reach process that is an iterative and dynamic process of modifying experts’ opinions more similar or closer to obtain the satisfying group solution. Considering the increasing complexity of the decision environment and the intricate relationship between the criteria, the Otsu method is applied to determine the threshold value of the total‐influence matrix that is the sum of the direct influence and indirect influence and thus eliminate some unnecessary influence. Finally, the feasibility of the improved method is illustrated by an example of information warfare and analysis. Comparative results are presented to show the effectiveness and advantages of the proposed method.

“…It is impractical to optimize all influential factors, a feasible way is to find out the critical success factors to improve By analyzing the above research status, most of the studies are a fusion of DEMATEL and fuzzy methods, such as fuzzy ANP [23], FAHP [10], fuzzy TOPSIS [11], HELTS [9], Grey [26], etc. But DEMATEL still has two defects: on the one hand, the limitation of their own knowledge and experience or the excessive subjectivity for experts lead to decisionmaking errors, so that the direct influence matrix cannot reflect the real influence relationship.…”

Interval‐valued Pythagorean fuzzy linguistic KPCA model based on TOPSIS and its application for emergency group decision making

“…The LVs can express personal preferences in vague language terms and use qualitative variables to describe the uncertainty of decision information. After the method was proposed, scholars combined the LVs with various FSs and used them in multiattribute decision making (MADM) 15,16 . Zhang et al 17 proposed interval‐valued intuitionistic uncertain LVs and applied them to the risk assessment of earthquake fire accident.…”
