基于Fuzzy-IPA的西南大学校园植物景观满意度测评研究

A Fuzzy-IPA-Based Satisfaction Evaluation Model of Campus Plant Landscape in Southwestern University

以西南大学校园植物景观为研究对象,运用三角模糊评价理论,采用三角模糊值表示被调查对象的感知表现,用连续性的变化更为客观地描述被调查对象感知值,并结合IPA分析法,构建基于Fuzzy-IPA分析法的满意度测评模型,不仅可筛选出影响西南大学校园植物景观的关键因子,而且可以找出相关因子的重要程度与表现程度.

The perception of plant landscape is subjective and uncertain,and the perception difference is continuous instead of discrete in a jumping and bounding state.Traditional perceptual performance measurement methods employ discrete numerical representations of state transitions,ignoring the perceptual buffer regions.Adopting the triangular fuzzy evaluation theory,this paper employs the triangular fuzzy value to represent the perceived performance of the surveyed objects and uses the continuous changes to describe the perceived value of the respondents with greater objectivity.Then a satisfaction evaluation model based on this approach in combination with IPA analysis is constructed,which can not only filter out the key factors affecting the plant landscape of Southwestern University Campus but also evaluate the degrees of the performance of the related factors and their importance.
