The focus of this paper is the knowledge gained from the engineers when solving production related problems and how this can be utilized when solving issues in the healthcare. Based on this, a research has been made where engineers have conceptualized and developed a simulation model for one polyclinic using real data. The simulation model is a hybrid one using Discrete Event Simulation and Agent Based Modelling approaches. It is created applying the basic principles of the queuing theory that is unavoidable even in the simplest production systems. The model simulates the patient flow in the polyclinic. By using experiments and analysis, what is the ideal number of resources with whom the waiting time of the patient would be under a certain time limit is suggested. This research showed that the possibilities of the application of simulations in healthcare and the benefits of their use are endless.
