Abstract:

Among traditional decision methods, such as TOPSIS and VIKOR, the maximum or minimum value is considered to be the best choice, but the best choice may occur between the maximum and minimum value in the real world, such as the temperature suitable for plant growth. Meanwhile, q-rung orthopair fuzzy set (q-ROFS) can help decision-makers express their opinions freely and comprehensively in the face of complex decision-making problems.To solve the problems of unreasonable determination of ideal solution and rank reversal in existing decision-making methods, a multi-criteria decision-making method based on q-ROFS and reference ideal method (RIM) is proposed. Firstly, the q-rung orthopair fuzzy (q-ROF) possibility degree and q-ROFS cross entropy are defined respectively, and their related properties are discussed; Secondly, the traditional RIM is extended in the q-ROF environment, and a multi-criteria decision-making model based on q-ROFRIM is built, where the q-ROF possibility degree is used to determine the optimal weight of the criteria, and the q-ROF cross entropy, as a measure of the information difference degree of q-ROF, is used to replace the distance measure in the traditional RIM. Finally, an example analysis illustrates the feasibility and effectiveness of the proposed method. In addition, comparison with previous methods shows that the proposed method not only makes the decision process more scientific and reasonable, but also avoids the rank reversal problem.
