Ambulance location for maximum survival
Erkut, Erhan; Ingolfsson, A.; Erdoğan, G. (Wiley, 2008-02)This article proposes new location models for emergency medical service stations. The models are generated by incorporating a survival function into existing covering models. A survival function is a monotonically decreasing ... -
Approximating vehicle dispatch probabilities for emergency service systems with location-specific service times and multiple units per location
Budge, S.; Ingolfsson, A.; Erkut, Erhan (Informs, 2009-02)To calculate many of the important performance measures for an emergency response system, one requires knowledge of the probability that a particular server will respond to an incoming call at a particular location. ... -
Computational comparison of five maximal covering models for locating ambulances
Erkut, Erhan; Ingolfsson, A.; Sim, T.; Erdoğan, Güneş (Wiley, 2009-01)This article categorizes existing maximum coverage optimization models for locatingambulances based on whether the models incorporate uncertainty about (1) ambulanceavailability and (2) response times. Data from Edmonton, ... -
Optimal ambulance location with random delays and travel times
Ingolfsson, A.; Budge, S.; Erkut, Erhan (Springer Science+Business Media, 2008-09)We describe an ambulance location optimization model that minimizes the number of ambulances needed tonprovide a specified service level. The model measures service level as the fraction of calls reached within a given ... -
Scheduling ambulance crews for maximum coverage
Erdoğan, Güneş; Erkut, Erhan; Ingolfsson, A.; Laporte, G. (Palgrave MacMillan, 2010-04)This paper addresses the problem of scheduling ambulance crews in order to maximize the coverage throughout a planning horizon. The problem includes the subproblem of locating ambulances to maximize expected coverage with ...
