Comparison of System Dynamics and Discrete Event Simulation Approaches.

The major concern in any engineering problem is to improve the ongoing system. While planning the improvement strategies, there are various applications to check for suggested implications. Usage of computers simplifies these applications by simulation techniques. Especially in industrial engineering, simulation is a popular modeling instrument. Simulation has various types which can be selected depending on the nature and objectives of the problem. Within a wide spectrum, discrete event and system dynamics simulation techniques are chosen for this study. The aim is to compare these two methods with two perspectives; existing work specifically on healthcare and basic simulation modeling steps. Comparison starts with the main modeling procedures are "adapted" for these two methods and used to clarify the differences between these two popular simulation techniques. In the following step, existing studies on healthcare are compared by classifying them according to nature of the problem.
