基于犹豫模糊语言信息的前景决策方法

本文首先回顾了模糊信息下前景理论研究的现状，发现犹豫模糊语言这一决策中常见的信息表达形式在前景理论框架中的研究被忽略，同时犹豫模糊环境下的前景决策方法具有一定的应用背景；基于此，本文考虑到决策者在实际决策过程中惯用的信息表达以及面对收益和损失时不同的风险态度，试图在犹豫模糊语言环境下构造新的前景理论决策框架，建立基于犹豫模糊语言信息的前景决策方法，并给出具体的决策步骤；最后通过算例分析展示了该方法的实际应用过程，并与犹豫模糊语言环境下的期望效用决策结果进行对比，说明了该方法更符合实际决策情景。

Prospect Decision-making Method Based on Hesitant Fuzzy Linguistic Information

The hesitant fuzzy linguistic information is a very general way to express the evaluation information of the decision makers. Also, the prospect theory is a popular framework to portray the different risk attitudes of the decision makers for gains and losses in real decision-making. Considering both the uncertain decision-making situations and the expressions of evaluation information, a prospect decision-making method is developed based on hesitant fuzzy linguistic information. Furthermore, the detailed steps and the visual procedure of the proposed method are given. Finally, the feasibility and the effectiveness of this method are verified by the comparative analysis in case study. The data of the case is derived from the questionnaire of the experts. The comparative result shows that decision-making with prospect framework is superior to the utility framework because of the risk attitude in former one. The construction of the prospect decision-making method with hesitant fuzzy information will promote more researches to focus on the behavior decision-making with fuzzy information.
