Summary Understanding people behavior and movement characteristics during building evacuation is valuable in evaluating building designs and the effectiveness of evacuation policies. Simulation can be a powerful tool since real data on building evacuation are rarely available and costly to obtain. On the other hand, state-of-the-art in evacuation modeling is the use of agent-based simulations, which...
Summary This paper provides a viable and practical solution to the challenge of real-time estimation of the number of people in areas of a building, during an emergency egress situation. Such estimates would be extremely valuable to first responders to aid in egress management, search-and-rescue, and other emergency response tactics. The approach of this paper uses an extended Kalman filter, which...
A real-world planned maintenance scheduling problem that exists at several business units within United Technologies Corporation (UTC) is addressed in this paper. The scheduling problem is formulated as a multiple tour maximum collection problem with time-dependent rewards and an adaptive memory tabu search heuristic is developed to solve it. The effectiveness of the proposed solution approach is...
