摘要

This report summarizes the efforts of the third and final year of a project to develop EVACNET+, a user friendly computer program that models building evacuations. 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 'transshipment' network, and solves the dynamic network problem using a capacitated minimum cost network flow algorithm. The solution obtained gives a time-dependent plan to evacuate the building in a minimum time, and identifies building evacuation bottlenecks. In the first year of the grant, EVACNET+ was developed to the point of preliminary testing. During the second year, the coding of EVACNET+ was completed and a user's manual was written. This final year of the grant concentrated on research related to extensions of the EVACNET+ concept. Areas of research included investigating: Time-varying extensions of EVACNET+; A model controlled adjustment option; Integration of EVACNET+ with other models; New solution procedures for EVACNET+; Expanded model input and editing functions; A result data base analysis system. A microcomputer version of EVACNET+ was also developed for the IBM PC or equivalent.
