This project will develop advanced InformationTechnology tools, mathematical models, and prototype infrastructure for disaster modeling and management. The project will bring comprehensive information and numerical prediction where it is needed, at the disaster command center, in real time. The system will incorporate large volume of information from data streams, e.g., as maps, sensor, surveyance, and weather data, and the mathematical model will run on remote supercomputers. The model will be controlled by dynamically available data, and the results visualized in distributed devices, like laptops and palmtops connected to the Internet by wireless ethernet and a broadband satellite link. Other sensors and airborne imagers will also be networked wirelessly. The core of the envisioned modeling system will be an existing computer model of wildland and weather around the area, adn these models will be rewritten from scratch using modern software engineering methodology as a data driven application, and enhanced by new mathematical modeling techniques together with advanced statistical techniques will be used to manage uncertainty. High-performance middleware will be used to connect omputational nodes, sensor nodes, surveyance nodes, and visualization nodes into a distributed information and modeling system. New network software technologies will make the communication between the nodes secure and provide quality of service guarantees. The system will be designed to tolerate interruptions of communication, increased latencies, and node disappearances.

该项目将开发高级信息技术工具，数学模型和用于灾难建模和管理的原型基础架构。该项目将在灾难指挥中心实时提供全面的信息和数值预测。该系统将合并来自数据流的大量信息，例如，作为地图，传感器，测量和天气数据，数学模型将在远程超级计算机上运行。该模型将由动态可用的数据控制，并且在分布式设备中可视化的结果，例如通过无线以太网和宽带卫星链接连接到Internet的笔记本电脑和手掌台面。其他传感器和机载成像仪也将无线网络。 设想的建模系统的核心将是现有的野外计算机模型和该地区周围的天气，这些模型将使用现代软件工程方法作为数据驱动的应用程序从头开始重写，并通过新的数学建模技术以及先进的统计技术来增强这些模型，并将使用高级统计技术来改善。高性能中间件将用于连接计算节点，传感器节点，测量节点和可视化节点，以分布式信息和建模系统。新的网络软件技术将使节点之间的通信安全并提供服务质量保证。该系统将旨在容忍通信，延迟增加和节点消失的中断。
