Abstract |
A simulation model for evaluating the performance of an emergency response fleet of an electric utility company is presented. The proposed model considers the spatial, temporal, and severity distribution of calls and has the capability to simulate alternative configurations of service districts and dispatching policies of the emergency response fleet. A nonstationary Poisson process is used to simulate the temporal distribution of service calls, whereas discrete simulation is employed for the spatial and severity distribution of the service calls. A mixed planar and network model is used to calculate the shortest travel time between the service calls and the location of emergency response vehicles. The model is validated on the basis of historical data. It is used to evaluate the relationship between fleet size and total incident service time and to compare alternative configurations of service districts for the same fleet size and dispatching policy.
