Materials and Methods: After an exploratory study, data gathering and building similar structured in order to determine geriatrics number prediction by considering the important factors. Causal loop diagram to show relationship between variables, stock-flow diagrams for quantitative analysis of system dynamic behavior was conducted and model equations in Vensim software version 5 used.
Results: After simulation, intake students' simulated model revealed increased trend then a sharp decline and finally the pattern had fixed trend from 2009 to 2012. Pattern of physician who was still in study and also graduated physician was in growing trend.
