  1. Knowledge Engine for Emergency Response Services -Dr. E. Douglas Harris, Associate Dean and Executive Director, Cyber Security & Emergency Preparedness Institute. -Dr. Bhavani Thuraisingham, Professor and Director, Cyber Security Research Center. -Dr.Ovidiu Daescu, Assistant Professor,  Department of Computer Science  University of Texas at Dallas.

  2. Organization of this Presentation • Motivation. • Challenges Involved. • How the Knowledge Engine meets these challenges. • Architecture. • Automation / Flowchart. • An application – ArcGIS based Routing.

  3. Motivating Scenario: • Due to an accident in a chemical processing plant or collision of a chemical carrying truck, a hazardous airborne chemical is released into an inhabited area. • Only few members of the team know the area. • Multiple departments and agencies from different counties must cooperate to evacuate the population and contain the leak as quickly as possible. • Internet access is intermittent, cell phone towers are overloaded and information is pouring from different sources.

  4. Challenges Involved: • Action must be taken within hours to avoid further casualties. • Efficiency of the response team depends on how timely and well-informed they are. • A great deal of collaboration and coordination is required as large quantities of data comes from different sources and multiple response teams from various departments are involved.

  5. The Solution: Knowledge Engine (KE) • Automates the decision making process as much as possible. • Aggregates the data from all sources into a single, coherent source of reference. • Exposes only the necessary information. • Encapsulates detailed data for further reference. • Ensures that the existing security and integrity of data is maintained. • Provides necessary information as quickly as possible

  6. KE and iCITTM together, they can provide : • iCIT is an incident management tool developed by CH2M Hill, based on Groove Virtual Office. • Incident Response and Consequence Management • With a single, shared, real-time map • Dynamically update the data in the workspace. • Integrates ArcGIS’s Network Analyst. • Scalable as the incident grows • Local, regional, national (roll-up with the same application)

  7. Architecture: Intermittent connections iCIT Groove E-Plan Web server Persistent connections Field users Knowledge Engine NDFD Weather Web Service EOC users Local Database

  8. Knowledge Engine Integrates and Automates… • The process of retrieving the weather information at the accident location for the ALOHA based plume modeling. • Retrieving chemical inventory from E-plan server. • Assumes worst case scenario if sufficient data is not available and continues with the plume modeling. • Integrates the ArcGIS “Network Analyst” for finding safe and shortest paths in presence of chemical dispersions. (currently working)
