The evacuation plan design under uncertain times of transportation

摘要

When the population of a given set of municipalities are endangered by some threat, casualties can be avoided by evacuation of the endangered population to safer refuges. When an evacuation plan is designed, vehicles are assigned to the evacuated municipalities so that the entire population is evacuated in a minimal time. Nevertheless, the transportation times in the associated road network depend on many unpredictable circumstances and this makes them uncertain. This paper deals with an approach, which processes the uncertainty making use of the theory of fuzzy sets. Furthermore, the presented approach uses a special feature of professional IP-solver to find the optimal solution of the evacuation plan design problem in acceptable computation time.
