犹豫模糊语言偏好关系是一种新兴的信息表达形式，它能够更加全面地表征决策者的定性决策信息，特别是以语言表达式形式给出的复杂语言信息，其在实际决策问题中尤其在群体决策问题中具有广泛的应用前景。本项目将系统深入地研究基于犹豫模糊语言偏好信息的一致性与交互式决策理论及其在川酒品牌管理和四川省水资源管理等决策问题中的应用。具体内容包括：研究犹豫模糊语言偏好关系的一致性理论；研究犹豫模糊语言偏好关系的交互式决策方法；研究犹豫模糊语言偏好关系的群体共识理论；探讨犹豫模糊语言偏好关系的大规模群体决策理论与方法；将上述理论研究成果应用于川酒品牌管理问题和四川省水资源管理问题中。

The hesitant fuzzy linguistic preference relation (HFLPR) is a new tool to represent the decision makers’ qualitative decision making information more comprehensively, especially for the complicated linguistic information that is given as linguistic expressions. The HFLPR has a wide application prospect in practical decision making problems, especially in group decision making problems. The aim of this project is to investigate the consistency and interactive decision theory based on the hesitant fuzzy linguistic preference information and its applications to Sichuan liquor brands management and the water resources management problems in Sichuan province. It includes the following contents: (1) this project studies the consistency theory of HFLPRs; (2) this project studies the interactive decision theory and methods of HFLPRs, (3) this project investigates the group consensus theory of HFLPRs; (4) this project develops the large scale group decision making methods; (5) In the application level, this project applies the above research achievements into the Sichuan liquor brands management and the water resources management problems in Sichuan province.
