Abstract :

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