MODELING AND ANALYSIS OF SUSTAINABILITY OF DECISIONS ON LOCATION AND NUMBER OF TEAMS IN CENTERS FOR EMERGENCY MEDICAL ASSISTANCE

Kiril Karagyozov, Petya Stoyanova

The report is based on research that uses a combined approach of analytical and simulation modeling, allowing to objectify the indicators of team turnover and the number needed to provide a given level of service. 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. 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.

Using a simulation model implemented at GPSS World, the stability of the optimization solutions for location is studied and an analysis is made regarding the number of emergency teams in each EMA center, with changes in the call intensity - 0.5, 0.75, 1.25, 1.5 and 2 times the base intensity of emergency calls 0.213 pcs / min., as well as in case of increase of the service times. For the basic model, with 4 bases centers of emergency medical assistance, 20 emergency teams are needed to provide a red code A1 red - to 8 minutes, providing coverage by area and population corresponding to LOS level 0.95. Dependencies of the total number of teams on the system load are obtained.
