Description

  The present invention relates to a decision support system that supports decision making when a case occurs.

  The government offices installed in each prefecture have a disaster prevention system such as a disaster response headquarters in preparation for natural disasters such as large-scale earthquakes and volcanic activities. When a natural disaster occurs, information collected through various communication means such as telephone, facsimile, e-mail, etc. is organized and aggregated, and reports to related organizations and necessary emergency measures are implemented.

  Conventionally, information collected via communication means at the time of a disaster has been recorded so that the person in charge records it on paper media, or transcribes it on a whiteboard as necessary, and transmits it to the relevant parties. It was.

  At the time of disaster countermeasures, information from multiple communication means is complicated, so it is difficult to organize information by handwriting on paper media or whiteboard, and there is a limit to the information that can be transmitted and shared simultaneously due to physical restrictions. It was. Furthermore, the response status by handwriting has been an obstacle to quick and accurate disaster countermeasures. In the worst case, the collected information could be accidentally destroyed without sufficient action.

  Patent Document 1 discloses a disaster decision support apparatus and system that can sequentially present countermeasures predetermined for disaster-related information to a person in charge of countermeasures.

  In Patent Document 2, in order to distribute information necessary for decision-making, an event that causes decision-making is detected, task allocation according to the event and information to be notified are indicated for each information according to the event. An apparatus for determining using the above correlation is disclosed.

JP 2000-048073 A JP2013-088829A

  However, Patent Document 1 does not disclose a support method when an unexpected case that is not defined in advance by the disaster prevention plan rule occurs.

  Also, in Patent Document 2, it is necessary for a task execution person to actively acquire event-related information, and to acquire more important information from a huge amount of disaster information that accumulates and changes every moment. Was difficult. Moreover, although the decision support apparatus is premised on receiving the latest road information, the latest road information may not be received depending on the disaster situation.

  The present invention has been made in view of the above problems, and can automatically display the contents set in advance when the monitoring criteria set in advance for the collected case information are satisfied. The purpose is to provide a decision support system.
