Fundamental Study on a Decision-making Support Method for Railway Transportation Recovery Strategy after Large-scale Disasters

Abstract

In a railway business, recovery strategies for quick recovery of railway transportation after large-scale disasters are becoming important more and more. First, this paper describes a mathematical algorithm for calculating a railway network recovery plan constituting a basic part of a decision-making support method of a railway transportation recovery strategy. Secondly, it describes the outline and the result of the recovery simulation conducted to verify the feasibility and validity of the algorithm. Finally, it outlines the development status of other parts of the decision-making support method except the algorithm. It also outlines future development plans of the method.
