DDDAS Initiative Launched (March 2000) DDDAS (Dynamic Data Driven Applications Systems) DEFINTION of DDDAS (2000/NSF Workshop) InfoSymbiotic Systems DDDAS: ability to dynamically incorporate additional data into an executing application, and in reverse, ability of an application to dynamically steer the measurement process Challenges : Application Modeling/Simulations Methods Algorithmic Stability Measurement/Instrumentation Methods Computing Systems Software Support Instrumentation -> Synergistic, Multidisciplinary Research Observation/Actuation Dynamic Capabilities : Feedback & Control more accurate understanding/prediction systems characteristics/behaviors Loop speeding-up simulation/modeling, by replacing computation with instrumentation data in specific parts of the phase-space of the model improve accuracy of the model by augmenting the model with actual data to improve analysis/prediction capabilities of application models dynamically manage/schedule/architect heterogeneous resources (2000/NSF Workshop) networks of heterogeneous sensors or controllers detect and mitigate sensor failures Dynamic Integration of Computation & Measurements/Data enable decision-support capabilities with simulation/modeling accuracy Unification of Computing Platforms & Sensors/Instruments (from the High-End to the Real-Time, to the PDA) 3 DDDAS – > architecting & adaptive management of sensor systems

QUO VADIMUS Moving into the future there is a confluence of needs and technological advances: Increasingly we deal with systems-of-systems & systems/environments that are complex | heterogeneous | multimodal | multiscale | dynamic Need to understand characteristics/behaviors: design – operation – evolution – interoperability – maintenance -- lifecycle Ad-hoc methods are not enough – need modeling not only for design but entire file-cycle Data alone is not enough Data is not the 4 th paradigm… - Data is the primordial paradigm Data Analytics is not enough - We need Systems Analytics ML alone is not enough -> …. Models Data …. DDDAS/InfoSymbiotics has shown: comprehensive, principle-based models rendered more efficient and accurate understanding, prediction, and real-time decision support with the accuracy of full-scale models dynamic and adaptive coordination of heterogeneous resources abilities, and ensuring fault tolerance DDDAS/InfoSymbiotics - timely now more than ever: increased emphasis in complex systems multi-scale/multi-modal modeling/algorithmic methods ubiquitous sensing, networks of heterogeneous collections of sensors/controllers large-scale-big-computing – large-scale-big-data; increased computation and communication capabilities enable and exploit these capabilities Some New Opportunities Areas: Test&Evaluation: embedded sensors&actuators (physical and software); additive manufacturing DDDAS-based adaptivity to improve performance, system evolution adaptivity – interoperability - maintenance; No longer limited to the design (“breadboarding”) cycle – T&E become a lifecycle process 5G&Beyond: 7 DDDAS-based methods for adaptive coordination of heterogeneous resources; optimization of performance, energy, QoS
