The publications that relate to the application of simulation to healthcare sector have steadily increased over the years. Many problems such as management of inpatient bed availability, reduction of patient waiting time, determination of the number of hospital staff and optimization of surgical material distribution processes can be overcame by the use of simulations. The study aimed to increase the working time and the number of doctors employed in the National Health Service and to reduce the patient waiting time by simulating Ondokuz Mayi{dotless}s University, Medical Faculty Department of Neurosurgery. Various scenarios were created using different numbers of doctors and working time to obtain data. These data were evaluated using various statistical analyses.
