Green supply chain has developed rapidly due to the advocacy of ecological civilization, and choosing a proper green supplier is a crucial issue. Considering the fuzziness of evaluation information and the psychological states of decision makers (DMs) in selecting process, a novel TODIM based on prospect theory with q-rung orthopair fuzzy set (q-ROFS) is proposed. The novel TODIM concerns both the perceived transformed probability weighting function and the differences in risk attitudes. A new distance, which concerns the herd mentality, is carried out to measure the perceived difference of the q-ROFS. Besides, a new systematic evaluation index system, named as PCEM (Product, Cooperation ability, Environment, Market), has been established. A case related to pork supplier companies is presented and fully demonstrates the effectiveness of the novel TODIM when compared with the extended one, the intuitionistic fuzzy TODIM, the Pythagorean fuzzy TODIM as well as the TOPSIS with q-ROFS. Finally, a series of comparative analyses illustrate the advantages of the proposed TODIM.

基于前景理论的新型TODIM用Q-RUNG矫形器模糊装置选择绿色供应商

绿色供应链在生态文明的倡导下发展迅速，选择合适的绿色供应商是一个至关重要的问题。考虑到评价信息的模糊性和决策者(DMs)在选择过程中的心理状态，提出了一种基于前景理论的Q-Rung orthopair模糊集(q-ROFS)TODIM。新颖的 TODIM 既涉及感知转换概率权重函数，也涉及风险态度的差异。执行一个新的距离，它涉及从众心理，以测量 q-ROFS 的感知差异。此外，还建立了一个新的系统评价指标体系，命名为PCEM（产品、合作能力、环境、市场）。提出了一个与猪肉供应商相关的案例，充分证明了新型 TODIM 与扩展模型、直觉模糊 TODIM、毕达哥拉斯模糊 TODIM 以及带有 q-ROFS 的 TOPSIS 相比的有效性。最后，一系列比较分析说明了所提出的 TODIM 的优点。
