Abstract
In order to solve the subjectivity and uniformity problem in index weighting and convey the preference of the decision maker in technical evaluation for road network, this paper establishes the technical evaluation index system of road network at first; then improves the traditional DEA method by using AHP method to set constraints for weight coefficient of input and output indexes, adds the AHP restraint cone to DEA evaluation model and builds the DEA model with AHP restraint cone; at last, uses this model to evaluate nine road network including Shanghai, Henan, etc. and obtain evaluation scores, rankings and improvements of each road network. The results show that DEA technical evaluation model with AHP restraint cone is strong practical and more realistic.
