Navy Awards CogniTech Contract to Develop Chemical Detection Systems Simulation Environment
Salt Lake City -- CogniTech is developing a chemical detection systems simulation environment for the Office of Naval Research under Contract N00014-01-M-0131, titled, "Simulating Data for the Development of Decision-Making Systems" . The chemical and biological detection processes contains a number of component processes, including the generation of a vapor cloud, atmospheric transport, large-scale meteorology, sensor hardware, sensor software, sensor fusion and decision support systems. These processes can be represented as system of sub-system models. The constituent simulations are characterized by model semantics, parameters and metrics, which include domain of applicability, dynamic state evolution, simulation time scales, resolution, fidelity, uncertainty, and robustness. The architecture incorporates these characteristics by integrating distributed software interfaces and supporting chaining of simulation outputs, errors, noise, uncertainty, and perturbation disturbances. It securely integrates databases and process models, including a wide variety of sensor and environmental data interchange formats. The architecture also facilitates the verification and validation of models and simulations using ground truth data.
