基于区间数层次分析法和CIM模型的高速公路投资风险评估

Expressway Investment Risk Assessment Based on Interval Number AHP and CIM Model

本文采用区间数的层次分析法,确定出高速公路投资风险各影响因素的权重范围。又建立了控制区间和记忆(CIM)模型对高速公路投资风险进行评估,通过控制区间和记忆模型在工程实践中的应用,得出高速公路投资风险。

In this paper, interval number AHP is used to determine the weight range of the influencing factors of expressway investment risk, and the controlled interval and memory （CIM） model is established to evaluate the expressway investment risk. Through the application of CIM model in engineering practice, the expressway investment risk is obtained.
