Fuzzy comprehensive evaluation of humanistic characteristics of smart tunnels

Abstract

The smart tunnel concept has emerged to optimize the construction and operation of resources and functions. However, difficulties remain in comprehensively evaluating the degree of wisdom in this area and in scientifically guiding top-level design. To emphasize the humanistic spirit and concept of human-oriented smart tunnels, this study adopts the analytic hierarchy process (AHP)-based fuzzy comprehensive evaluation method is used to comprehensively evaluate the humanistic characteristics of tunnels, which have been previously ignored in the literature. The satisfaction of human needs is selected as the objective performance indicator, while the social value of tunnels is selected as the subjective guiding indicator. A three-level evaluation index system containing 3 first-level indexes, 6 second-level indexes, and 22 third-level indexes is built. The judgment matrix is established using the improved AHP, while the membership function is constructed on the basis of fuzzy theory. This study ultimately realizes the comprehensive evaluation of the humanistic attributes of smart tunnels. Taking the Bo’ao tunnel in Hangzhou as a typical case, this work demonstrates the reliability and practicability of the proposed evaluation system, which is expected to benefit the construction of tunnels from a humanistic perspective.
