犹豫模糊环境下的西安硬科技企业合作创新风险评估研究

Research on Risk Assessment of Xi'an Hard Technology Enterprise Cooperative Innovation under Hesitant Fuzzy Environment

针对不同专家对企业合作风险认知的不确定性和模糊性,将企业合作创新的风险评估视为属性值为犹豫模糊元的多属性决策问题,同时考虑到决策者对风险的偏好,引入前景理论,建立一种基于前景理论和犹豫模糊集的合作创新风险评估方法。该方法充分考虑了人们面临损益时的风险偏好差异,解决了传统方法直接以欧几里得距离作为评价标准的不合理问题,使得决策行为具有了偏好意识,使决策结果更加合理。

In view of the uncertainty and ambiguity of different experts'perceptions of enterprise cooperative risk,consider enterprise cooperative innovation risk assessment as a multi-attribute decision problem whose attribute values are hesitant fuzzy elements.At the same time,considering the decision makers'risk preference,this paper introduces Foreground theory,establishes a cooperative innovation risk assessment method based on foreground theory and hesitant fuzzy set.This method fully considers the differences in people's risk appetite,and solves the unreasonable problem of traditional method which directly uses Euclidean distance as the evaluation criterion,so that make the decision-making behavior have a sense of preference and make decision results more reasonable.
