Abstract (in Japanese) (See Japanese page) 
(in English) The emergency management handled by the staffs in decision making and planning layers of the organization can be broadly divided into two cycles. The first is the PDCA cycle including before and after the incident occurrence, which is a relatively long term and consists of preparations before an incident event occurs (Plan), incident response after occurrence (Do), review after action (Check), and improve after review (Action). The second is the OODA loop as the situation of incident response (Do) in the above PDCA cycle changes, which is a relatively short period and consists of surveillance to grasp the current situation (Observe), situation judgment based on information obtained by surveillance (Orient), decision making based on situation judgment (Decide), actions based on policies adopted in decision making (Act). The authors have been researching and developing the system "KADAN®" that supports incident response to complex risks such as natural disasters and cyber-attacks so far. We also validated KADAN® at large international sports events and confirmed its usefulness. In the past verification, it was carried out for part of the PDCA cycle and OODA loop by using KADAN®. In this paper, we consider the method of risk estimation necessary for transition from “Observe” to “Orient” in OODA loop based on analysis of communication log in an incident response.
