A Novel Operator to Solve Decision-Making Problems Under Trapezoidal Fuzzy Multi Numbers and Its Application

This article investigates solutions to multiple attribute decision-making (MADM) problems in which the values take form of trapezoidal fuzzy multi-numbers. To do this, this paper proposes a kind mean aggregation operator called Bonferroni harmonic for aggregating information. Then, an approach that is solution algorithm has been developed find multi-attribute problems. Afterwards, illustrative example given verify and show its usefulness efficiency. Finally, comparison table presented compare proposed method with some existing methods.
