SIMULATION MODEL FOR DETERMINING THE D NUMBER OF EMERGENCY CREWS AT A FIXED NUMBER AND LOCATION OF EMERGENCY CENTERS FOR THE CITY OF SOFIA

Kiril Karagyozov, Petya Stoyanova

By using models to select the number and location are determined variants of the structure of the centers for emergency medical assistance (EMA) and their coverage (service) of a given geographical area. Main indicators on the basis of which it is estimated the number and location of mobile teams for emergency medical care are access time, population density, the opportunity to cover the area of more than 1 team. Their number and location are determined on the basis of affiliation to the set standard in execution of calls with Code Red-8 min in service of emergency calls. The developed simulation model has been applied to Sofia-city, which has specific phases of movement and stay with certain time frames, in implementation of the calls for a predetermined number of base stations-3, 4 and 5 centers and their coverage by area and population. The flow of these emergency calls from any of the 24 area has a Poisson probability distribution related to the population in the area, and the service is from the relevant for this area EMA center.Time for employment of a team is formed by the times to travel to the location of the call, carrying out service on place, movement and delivery to the hospital and returning to the EMA center. The main application of the GPSS World`s computerized simulation model is to evaluate optimization solutions to identify the d number of emergency teams in each EMA center so as to provide the set service level.
