Applications of discrete event simulation: A literature review

Abstract

This review article presents how various authors have used discrete event simulation to improve an existing system with the least financial involvement and no downtimes to conduct the study. The simulation process has proven to be efficient in most cases and was able to identify the system bottlenecks, critical areas, and suggest necessary improvements which could be implemented in real life. Further use of simulation software such as ARENA has proven how diverse its use has been. It could be used anywhere from a critical emergency ward to a local store to check the system performance, find out where it's lacking, work out various alternate scenarios, put it into test, and implement it all without disturbing the actual system.
