This paper focuses on the bus evacuation problem with pedestrians’short-distance walking ability between bus stations during no-notice disasters in downtown areas.A mixed-integer linear programming model is proposed ...
As China’s population ages and the notion of contemporary people evolves,an increasing number of elderly people opt to spend their final years in a nursing home.Recently,there have been more fires in nursing faciliti...
