大規模災害後の外貿コンテナ貨物の代替港湾の取扱能力と輸送経路の推計

Abstract

At the Great East Japan Earthquake, the port facilities of east Japan on the Pacific suffered severe damage: this led stagnation of international container transport, caused interception of the supply chain of many companies and let the economic damage extend. For the countermeasures, Port-BCPs (Business Continuity Plan for port management) are now being developed. One of the most important issues of Port-BCP is to identify the alternative port for compensating the supply-demand gap at damaged port. Against this background, this study targets the international containerized cargo transport and conducts: (1) the analysis of alternative port after the Great East Japan Earthquake by using PIERS data, (2) the estimation of container handling capacity of alternative port after large scale disaster and (3) the development of estimation model for alternative port/route with consideration of the handling capacity limit of alternative port.
