- Abstract
- This report summarizes the efforts of the second year of a project to develop user friendly software for the network modeling of building evacuation. When the evacuation of a building involves the flow of people through well defined passageways, it is natural to consider the evacuation problem to be a network flow problem. EVACNET+ is a user friendly interactive computer program that accepts a user defined network model of a building, converts that model to a time expanded dynamic "transhipment" network, and solves the dynamic network using a capacitated minimum cost network flow algorithm. The solved dynamic network gives a time-dependent plan to evacuate the building in a minimum time, and identified building evacuation bottlenecks. In the first year of the grant, EVACNET+ was developed to the point of preliminary testing. During the second year, the development of EVACNET+ was completed.
