A Group Decision Making Approach Considering Self-Confidence Behaviors and Its Application in Environmental Pollution Emergency Management

Abstract

Self-confidence as one of the human psychological behaviors has important influence on emergency management decision making, which has been ignored in existing methods. To fill this gap, we dedicate to design a group decision making approach considering self-confidence behaviors and apply it to the environmental pollution emergency management. In the proposed method, the self-confident fuzzy preference relations are utilized to express experts’ evaluations. This new type of preference relations allow experts to express multiple self-confidence levels when providing their evaluations, which can deal with the self-confidence of them well. To apply the proposed group decision making method to environmental pollution emergency management, a novel determination of the decision weights of experts is given combining the subjective and objective weights. The subjective weight can be directly assigned by organizer, while the objective weight is determined by the self-confidence degree of experts on their evaluations. Afterwards, by utilizing the weighted averaging operator, the individuals’ evaluations can be aggregated into a collective one. To do that, some operational laws for self-confident fuzzy preference relations are introduced. And then, a self-confidence score function is designed to get the best solution for environmental pollution emergency management. Finally, some analyses and discussions show that the proposed method is feasible and effective.

An Emergency Decision-Making Method for Probabilistic Linguistic Term Sets Extended by D Number Theory

“…Besides, an LTS S was provided to the experts for evaluation of the four possible alternative plans, as shown in Equation (9).…”

“…Taking candidate T 1 for example, the numbers of evaluation grade F and H on criteria A 1 are four and six, respectively, and which can be marked as {(F, 4), (H, 6)}. Since there were ten experts giving their opinions, then it can be normalized as {(F, 0.4), (H, 0.6)}, which can be rewritten as {(s 0 , 0.4), (s 1 , 0.6)} based on Equation (9). Then, summarizing all the evaluation information of LTS from in Table 2, it can be transferred into the form of PLTS information, as shown in Table 3.…”

“…In recent years, with the rapid development of society and the economy, a variety of emergency events has become one of the most serious problems [1,2], such as mining accidents [3], fire disasters [4], flood hazards [5], earthquakes [6], gas explosions [7], natural disasters [8], environmental pollution [9], and so on. Since many aspects should be taken into consideration, emergency decision-making can be viewed as one of the multi-attribute decision-making (MADM) problems [10][11][12].…”

A Literature Review of the Concepts of Resilience and Sustainability in Group Decision-Making

“…Liu et al in 2019 considered "self-confidence" as a component of human psychological behavior [99]. They applies this new index to the environmental pollution emergency management decision-making.…”

Rough-Number-Based Multiple-Criteria Group Decision-Making Method by Combining the BWM and Prospect Theory

“…A multiple-criteria decision-making (MCDM) problem, as one of the most significant problems in the fields of management, economics, and engineering, is the process of selecting the optimal option in all possible alternatives according to diverse criteria. Since the complexity and variety of decision-making environments determine that opinions of different decision-makers should be taken into account, multiple-criteria group decision-making (MCGDM) becomes research hotspot and is widely used in practical problems [1], such as supplier selection [2,3], emergency management [4,5], and product development [6,7]. Methods for solving MCDM problems, e.g., AHP [8], TOPSIS [9], VIKOR [10], and PROMETHEE [11], have been improved and applied to group decision-making problems.…”
