A dynamic multi-attribute group emergency decision making method considering experts’ hesitation

Abstract

Multi-attribute group emergency decision making (MAGEDM) has become a valuable research topic in the last few years due to its effectiveness and reliability in dealing with real-world emergency events (EEs). Dynamic evolution and uncertain information are remarkable features of EEs. The former means that information related to EEs is usually changing with time and the development of EEs. To make an effective and appropriate decision, such an important feature should be addressed during the emergency decision process; however, it has not yet been discussed in current MAGEDM problems. Uncertain information is a distinct feature of EEs, particularly in their early stage; hence, experts involved in a MAGEDM problem might hesitate when they provide their assessments on different alternatives concerning different criteria. Their hesitancy is a practical and inevitable issue, which plays an important role in dealing with EEs successfully, and should be also considered in real world MAGEDM problems. Nevertheless, it has been neglected in existing MAGEDM approaches. To manage such limitations, this study intends to propose a novel MAGEDM method that deals with not only the dynamic evolution of MAGEDM problems, but also takes into account uncertain information, including experts' hesitation. A case study is provided and comparisons with current approaches and related discussions are presented to illustrate the feasibility and validity of the proposed method.

An Emergency Decision Making Method for Different Situation Response Based on Game Theory and Prospect Theory

“…Despite existing EDM studies based on PT having achieved fruitful results [14,[16][17][18][36][37][38][39][40], they neglect an important fact that different emergency situations should be handled by using different measures because of the limited resources and dynamic evolution of EEs.…”

A new approach for emergency decision‐making based on zero‐sum game with Pythagorean fuzzy uncertain linguistic variables

“…They are regarded as one effective way for the determination of the optimal solution in emergency decision‐making (EDM). Thus, based on MCDM methods, many researches have been carried out to address EDM problems recently …”

“…Thus, based on MCDM methods, many researches have been carried out to address EDM problems recently. [10][11][12][13][14] In the real EDM process, because of the uncertainty and vagueness of emergency circumstances, decision-makers have difficulties to quantify their evaluations with precise values. 15 Instead, they tend to utilize using linguistic grades to express their opinions.…”

A Novel Method Based on Fuzzy Tensor Technique for Interval-Valued Intuitionistic Fuzzy Decision-Making with High-Dimension Data

“…Normally, multiple attribute group decision-making problems is that multiple decision-makers select the optimal alternatives or ranking them from a set of feasible alternatives by the attribute weights and attribute values, for details refers to Xu and Cai [1]. However in some real applications such as Xu and Cai [1], Liu et al [2], Wang et al [3], Qin et al [4], He [5], and Hashemi et al [6], due to the undetermined decision-making environment, the multi-attribute group decision-making seems to be useless for decision-making. One alternative dealing with this difficulty is the fuzzy set, which was subsequently extended to intuitionistic fuzzy set by Atanassov [7] for applications in various decision-making areas, and Atanassov and Gargov [8] presented the concept and properties of interval-valued intuitionistic fuzzy set based on intuitionistic fuzzy set in 1989, which enriched intuitionistic fuzzy set theory.…”
