Comprehensive evaluation method for subway green construction in limited space

The invention discloses a comprehensive evaluation method for subway green construction in a limited space based on multi-objective analytic hierarchy process and grey correlation method, which comprises the following steps: firstly, performing hierarchical refinement on targets of subway green construction in the limited space, and establishing a hierarchical model of a construction scheme; secondly, employing authoritative experts in various fields to perform empirical judgment on the index weight of each level, establishing a judgment matrix, performing consistency judgment on the judgmentmatrix, and then calculating the relative weight of each index to the total target layer by using an analytic hierarchy process; determining the most ideal scheme according to the actual condition, constructing an evaluation matrix in combination with the to-be-evaluated scheme, performing normalization processing, and determining a reference and comparison sequence; and calculating the correlation degree of the compariso
