Emergency Facilities Location Modeling Development In Transportation Network

This paper presents two mathematical models for locating and allocating emergency facilities in transportation network. The developed models has two capabilities: (1) it develops a mathematical Model for emergency facilities location in a network, (2) it determines the required level of service for each emergency facilities. Different from conventional methods, the proposed models for emergency facilities location adopts a risk-based approach that allows explicit consideration of both accidents probability and emergency response time. While covering the whole network according to the allowable response time, the model minimizes the total risk. The developed mathematical models provide a suitable response to the issue of emergency facilities location, type of emergency facilities and the level of service according to the degree of risk involved.
