You are presented with multiple paper abstracts, alongside the associated literature review and chapter titles. Given the provided information, you are going to do a literature review. Please generate a coherent literature review that synthesizes the content, draws connections between different works, highlights major findings, and identifies any gaps in the existing research.

Literature Review Title: COMBINING SYSTEM DYNAMICS AND DISCRETE EVENT SIMULATIONS - OVERVIEW OF HYBRID SIMULATION MODELS 
Chapter Title:  DISCRETE EVENT SIMULATION 
1. Abstract of Cited Paper (BIB001):  From the Publisher: ::: This second edition of Simulation Modeling and Analysis includes a chapter on "Simulation in Manufacturing Systems" and examples. The text is designed for a one-term or two-quarter course in simulation offered in departments of industrial engineering,business,computer science and operations research.

Literature Review:
DES is a more widely established simulation technique BIB001 . "The system is modelled as a series of events, that is, instants in time when a state-change occurs", (Robinson 2004 ). The models are stochastic and generally represent a queuing system. From the beginning until now, the models are based on a specific code that manages the simulation. At the beginning, DES was developed and used in the manufacturing sector. But, as the times have changed, so have the areas where DES has found its applicability (hospitals, public offices, document management etc.) Still, the main advantages and principles have never changed no matter if the simulated entities are products, people, documents etc. BIB002 Banks 1998) .
