L-R geometric consistency definition of triangular multiplicative preference relation in group decision making

Shuping Wan et al.

Summary: The paper proposes a new geometric consistency definition for TMPR with considerations of experts' trust levels and develops a new group decision-making method. A new approach for extracting experts' weights is presented, and two algorithms are established for individual decision-making and group decision-making with TMPRs, showing superiority in simulation results. L-R geometric consistency contributes to TMPR by considering experts' trust levels and demonstrating reciprocity, invariance, and robustness.

A new consistency definition of interval multiplicative preference relation

Xian-Juan Cheng et al.

Summary: This paper introduces a new consistency definition of interval multiplicative preference relation (IMPR) with robustness and invariance. Comparative analyses are conducted to reveal the relationships among different consistency definitions. A new consistency index is introduced, along with an algorithm to improve consistency level and a goal programming model. A new individual decision making method with IMPR is proposed, supported by numerical examples and simulation analyses.

Decision making with incomplete interval multiplicative preference relations based on stochastic program and interval category

Shuping Wan et al.

Summary: This paper investigates decision making with incomplete IMPRs and proposes a new method to estimate missing values in incomplete IMPRs by minimizing a consistency index. Optimization models are constructed to obtain the most pessimistic and optimistic acceptably multiplicative consistent IMPRs, taking into account decision makers' risk attitudes.
