Planning Emergency Movement for the Built Environment

SSP Seminar Series
Thomas French

This talk will detail work investigating the planning of emergency movement for the built environment. It is proposed to model building circulation systems using stochastic, time-dependent flow networks that attempt to capture the uncertain and transient conditions of an emergency event. A stochastic combinatorial optimisation problem is formulated with the goal of finding plans that minimise the risk taken by the paths with the highest risk. We will detail the problem complexity and the proposed solution approach, based on Evolutionary Algorithms. For evaluation, the EA has been run on a set of random problem instances and compared against several baseline approaches, and we present experimental results that demonstrate that the EA performs better than the baseline approaches. Finally, we will also outline current work, applying the approach to a real building.
