Abstract:
1. An egress support system comprising: an input operably connected to receive a first occupant detection data, a second occupant detection data from an occupant detection device, and threat location data from an threat detection device; a threat propagation estimator operably connected to the input, the threat propagation estimator executes a threat propagation algorithm that generates a threat propagation estimate based on the received threat location data and a model-based threat propagation estimate generated by a threat propagation model; an egress controller operably connected to the input and including an optimization algorithm and a prediction model, wherein the threat propagation estimate is provided to the egress controller, and wherein the egress controller executes the optimization algorithm to select an optimal egress route based on model-based estimates generated by the prediction model in response to the first occupant detection data and the threat propagation estimate, and an alternate route based on model-based estimates generated by the prediction model in response to the second occupant detection data and the threat propagation estimate; and wherein the output is operably connected to provide control instructions generated by the egress controller based on the selected optimal egress route to occupant-based egress instructional devices that direct first occupants along the selected optimized egress route, and wherein the output is operably connected to provide control instructions generated by the egress controller based on the selected alternate egress route to occupant-based egress instructional devices that direct second occupants along the selected alternate egress route.
