Research Areas: application of M&S 1) Study of Natural Fire Hazard: Proposing an Integrated Predictive Modeling and Simulation Framework (HazFire) 2) A Model-based Imprecise Operating Systems for Critical Real-Time and Embedded Applications (iRTOS) 3) M&S of Segmented Multi-Path Data Transfer for Air-To- Ground Cellular Network (ATG) New Area:  Aviation-specific modeling for certifiable and safety- critical sw systems

HazFire M&S Framework Interdisciplinary approaches to address multiple aspects of natural fire: phenomenological and firefighting perspectives. Objective1 (research): study complex behavior of natural fire, develop methods to better render the consequences, incorporating meteorological data analysis as well as environmental factors using computational M&S methodologies. Objective2 (analysis): provide risk analysis and cost-benefit assessment strategies associated with the impact of natural fire hazards on community infrastructures. Objective3 (development): develop cross-cutting software framework (HazFire) to integrate natural fire behavior models, providing spatial representation of the location, real-time decision-support, prediction, visualization, and mitigation. Objective4 (cognition): ensure user-friendliness and usability for first responders and incident managers.

Hazfire System Architecture

iRTOS: imprecise RTOS Imprecise Computation-based real-time OS using IDEVS (imprecise DEVS) [best-paper Springsim TMS-DEVS 2012] – formal methodology for reliable design of RTOS – novel IC-based task scheduling algorithms – risk-free simulation-based testing before final deployment

iRTOS Goals Model continuity from simulation stage till embedding the system on the target hardware in an SDE design scheme. Providing a hardware-software co-design approach for designing the entire embedded system, where models represent different hardware and software components and are tested together as an integrated system. Offering a hardware-in-the-loop simulation platform where some of the models act as the simulated components working along with other actual hardware components.
