In this study, the queuing theory applications are applied two big hospitals in Istanbul during 2013-2014 years by measuring waiting time and services time and systems during different times in six months. Nursing shortages are often filled In health care, queuing models are generally based on three factors and the variation within. Queuing theory is concerned with studying all the various dynamics of lines - or "queues" - and how they may be made to operate more efficiently.
