In this survey, we briefly study on variants of arrival and service processes with different types of working vacation models. The concept of working vacations has wide range application in computer communication systems, manufacturing/production systems and inventory systems in particularly network service, web service, file transfer service and mail service etc. The motivation of this work is to provide sufficient information to analysts, managers and industry people who are interested in using queuing theory to model congestion problems and want to locate the details of relevant models. © 2016 Academic Publications, Ltd.
