ABSTRACT
In a large scale disaster, each organization must cooperate with the others strategically and follow guidelines for action and decision-making specified in a District Continuity Plan (DCP). In order to formulate the DCP, the priority of the district to recover must be determined. A District Impact Analysis (DIA) distinguishes critical districts with non-critical districts for the district continuity. However, it is difficult to obtain a consensus of these between many organizations which have conflict of interests. In this study, an attempt is made to develop a DIA support system for DCP. The proposed system presents important districts and connections between districts by using a network graph on Web mapping system. District continuity planner share local district information and they analyze important districts. Several examples are presented to demonstrate the applicability of the proposed system.
