Eight Innovative Dual Hesitant Fuzzy Aggregation Operators for Enhanced Decision Making
摘要
Dual hesitant fuzzy elements can simultaneously capture the hesitancy and uncertainty of information. Although significant progress has been made in dual hesitant fuzzy elements aggregation for multi-attribute decision-making, existing aggregation operators still lack idempotency, potentially leading to biased decision outcomes. To address this issue, this study proposes a series of novel dual hesitant fuzzy elements aggregation operators, and further establishes a corresponding decision-making method. Specifically, we firstly propose two normalized Einstein operations for dual hesitant fuzzy elements and define a novel comparison rule. Furthermore, several normalized Einstein aggregation operators are developed based on the provided normalized Einstein operations. What’s more, we establish a decision-making method for solving practical multi-attribute decision-making problems. In addition, two practical cases are conducted to demonstrate the feasibility and practicality of our method.
