Abstract: Analysis and optimum decision making in the emergency department of the hospital due to the variety of probabilistic events is a vital complex task. The most important task of a hospital emergency care is planning to provide patients with quick services and reducing their waiting time. The present research focused on such context and a computer simulation model presented based on surveying a flow of 357 patients. The validity of the simulation model examined by t student hypothesis testing and through scenario analysis, reduction of patient waiting time and increasing the human resource productivity followed to promote quality level of outpatients.

Keywords: hospital emergency; computer simulation; waiting time; human resource productivity; outpatients.
