Abstract

An embodiment of the invention includes a system, method and computer program product for managing dynamic events. The embodiment may include managing, by a first subsystem, an event in a first region of the plurality of geographic regions using a first event agent. The embodiment may include determining whether the event is predicted to spread from the first region to a second region. The embodiment may include generating a first dynamic event agent to monitor the event as a dynamic event based on predicting the event may spread from the first region to the second region. The first dynamic event agent may receive information relating to the dynamic event, update a status of the dynamic event based on the received information, and transmit the received information. The embodiment may include generating, by a second subsystem, a second dynamic event agent for handling the dynamic event in the second region.

Claims

1. A computer system for managing events in a plurality of geographic regions, the computer system comprising:

one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the program instructions comprising;

program instructions to manage, by a first subsystem, an event in a first region of the plurality of geographic regions using a first event agent;

program instructions to determine whether the event is predicted to spread from the first region to a second region of the plurality of geographic regions;

based on determining that the event is predicted to spread from the first region to the second region, program instructions to generate a first dynamic event agent to monitor the event as a dynamic event, wherein the first dynamic event agent comprises;

program instructions to receive information relating to the dynamic event; and

program instructions to update a status of the dynamic event based on the received information.

2. The system of claim 1, wherein determining that the event is predicted to leave the first region to the second region comprises program instructions to determine if a calculated probability that the second region will be affected by the dynamic event exceeds a threshold value.

3. The system of claim 1 further comprising:

program instructions to transmit the received information from the first subsystem to a second subsystem; and

program instructions to transmit, by the second subsystem, a signal based on information about the dynamic event to a mobile object in the second region.

4. The system of claim 3, wherein generating the second dynamic event agent comprises:

receiving a signal based on generating the first dynamic event agent; and

based on receiving the signal, generating the second dynamic event agent for handling the dynamic event in the second region.

5. The system of claim 3, wherein the second event server is operable to register the second dynamic event agent with the first dynamic event agent.

6. The system of claim 3, further comprising:

program instructions to generate, by a third subsystem, a third dynamic event agent for handling the dynamic event in the third region based on receiving a request issued by the second dynamic event agent.

7. The system of claim 6, wherein the second dynamic event agent issues the request to the third subsystem if a calculated probability that the third region will be affected by the dynamic event exceeds a threshold value.

8. The system of claim 6, further comprising:

program instructions to register the third dynamic event agent with the first dynamic event agent; and

program instructions to transmit a signal based on information about the dynamic event to a mobile object in the third region.

9. The system of claim 3, further comprising:

program instructions to maintain, by the first subsystem, a registry of all dynamic event agents that have been generated for handling the dynamic event;

program instructions to issue, to all subsystems of the plurality of subsystems having a dynamic event agent in the registry, a notification that the dynamic event is no longer occurring in the first region; and

based on receiving the notification that the dynamic event is no longer occurring, program instructions to eliminate, by the second subsystem, the second dynamic event agent.

10. The system of claim 9, wherein the second dynamic event server eliminates the second dynamic event agent when the dynamic event is no longer occurring in the second region after receipt of the notification by the second subsystem.

11. The system of claim 10, wherein

program instructions to notify the first subsystem, by the second subsystem, when the second dynamic event agent is eliminated;

and

program instructions to eliminate the first dynamic event agent when the dynamic event is no longer occurring in the first region and all dynamic event agents that were generated for handling the dynamic event have been eliminated.

12. The system of claim 1, wherein

program instructions for a second event agent, in the second subsystem, for handling events that occur in the second region;

and

program instructions to receive, by the second dynamic event agent, information relating to an event from a mobile object in the second region, update a status of the second dynamic event based on the information if the received information relates to the second dynamic event, and forward the received information to the second event agent if the received information relates to an event other than the second dynamic event.

13. The system of claim 1, wherein the first event server is operable to generate the first dynamic event agent before occurrence of the dynamic event based on statistical information about occurrence of events in the first region.

15. The system of claim 2 further comprising:

program instructions to estimate traffic congestion, by a first dynamic event agent, of a vehicle route in the first region caused by the dynamic event; and

program instructions to calculate, based on the estimated traffic congestion, the probability that the second region will be affected by the dynamic event.

16. The system of claim 1, wherein the dynamic event is a weather pattern, a fire, or a traffic condition.

14. The system of claim lfurther comprising:

program instructions to, by the first dynamic event agent, estimate traffic congestion of a vehicle route in the first region caused by the dynamic event; and

program instructions to transmit information about the estimated traffic congestion.

17. A method comprising:

managing, by a first subsystem, an event in a first region of the plurality of geographic regions using a first event agent;

determining whether the event is predicted to spread from the first region to a second region of the plurality of geographic regions;

based on determining that the event is predicted spread from the first region to the second region, generating a first dynamic event agent to monitor the event as a dynamic event, wherein the first dynamic event agent comprises;

receiving information relating to the dynamic event; and

updating a status of the dynamic event based on the received information.

18. A computer program product including a non-transitory computer readable storage medium having program instructions stored therein, comprising:

program instructions to manage, by a first subsystem, an event in a first region of the plurality of geographic regions using a first event agent;

program instructions to determine whether the event is predicted to spread from the first region to a second region of the plurality of geographic regions;

based on determining that the event is predicted to spread from the first region to the second region, program instructions to generate a first dynamic event agent to monitor the event as a dynamic event, wherein the first dynamic event agent comprises;

program instructions to receive information relating to the dynamic event; and

program instructions to update a status of the dynamic event based on the received information.
