“…System Requirements The integration of tools and data in a proper runtime are very important for decision making before the occurrence of an event characteristics. However, the architectural model for alert systems must offer the following essential requirements [6] and [7]: 9 Response time -for decision making, the results of the forecasts and hydrologic simulation must be submitted in the shortest possible time, thus the ability of computational processing is crucial to meet this demand; 9 Availability -if a service changes its location, condition, or in the presence of a hardware failure, the system should be able to manage this situation, so that the request is granted, the completed task, and the system will continue functioning normally transparently the user; 9 Reserve resources -it is desirable that a model for monitoring and alerting meets some criteria of quality of service. By booking and request on-demand resources can ensure the accomplishment of the task; 9 Real Time -the data must be collected in real time and the information should be generated by CEOPS before the occurrence of the event and with enough time for the Civil Defense agencies may implement the plan for defense.…”
