SPA Model on Repair Priority for Earthquake-damaged Transport Infrastructures

Abstract

Sequence is an important mission and performance in such repair decision-making operation for the earthquake-damaged transport infrastructures. Through introducing Set Pair Analysis ideology, the decision-making model was established for earthquake repair sequence of transport infrastructures. Then, the SPA comparing space was built, the association identity, contrary and difference degree parameters were calculated for repair projects, the relative SPA proximity was determined for each repair project, as well as the repair sequence was given. Meanwhile, the integration of Efficiency Coefficient method and Information Entropy to determine the index weights, improved the reliability of repair sequence. Finally, Case showed a typical evaluation index system and model application, which provided a scientific, simple and suitable method on the repair priority decision-making operation for the earthquake-damaged transport infrastructures.
