基于模糊直觉不确定语言信息的工程决策方法研究

Research on Engineering Decision Making Method Based on Fuzzy Intuitionistic Uncertain Linguistic Information

摘要: 工程决策的完成需要人们先对基本指标进行相应评价，再综合给出相应结论。但专家评价过程中，往往使用定性语言，本文将定性的语言表达与直觉不确定语言术语集的理论相结合，提出模糊直觉不确定语言术语集的概念。本文理论可以细腻刻画决策者的犹豫程度和决策环境的不确定性，并给出模糊直觉不确定语言术语的运算规则、比较方法和集成算子。进而给出相应的决策方法，并通过算例分析表明了该方法工程决策问题中的可行性。

Abstract: To successfully complete an engineering decision making, individuals must first analyze the fundamental indices and then synthesize the related findings. Qualitative language, on the other hand, is frequently utilized in expert evaluation. By merging qualitative language expression and the idea of intuitionistic uncertain language term sets, this article proposes the concept of fuzzy intuitionistic uncertain language term set. The theory presented in this article can precisely explain the degree of hesitation of the choice maker and the uncertainty of the decision environment, as well as the operation rules, comparison procedures, and integration operators for fuzzy intuitionistic uncertain language words. Then the appropriate decision procedure is presented, and the approach’s applicability to engineering choice problems is proven through an examination of a numerical example.
