• The Hyogoken-nambu (Hanshin-Awaji) Earthquake, which struck Japan on 17 January 1995,was a typical large-scale multiplex disaster which brought the functions of the urban infrastructure systems to a complete halt. The region was beset by deadlocks in the restoration and/or restructuring process of the urban infrastructure systems which were damaged in this disaster. We propose a Petri-net model that describes visually the parallel dynamic relations between urban infrastructure facilities and social activities, including restoration and restructuring activities. With this method we analyzed the bottlenecks which cause deadlocks in the social dynamic process using the reachability tree of the Petri-net model. We also developed some appropriate restoration and/or restructuring processes for disaster damage.
