Advantages Of Simulation In Healthcare Systems
Simulation has been used to analyze many issues in the healthcare sector for over 40 years [1]. Such issues that have been addressed by simulation include, but not limited to; improving patients' workflows and throughput time, reducing waiting times, resources allocation and optimization, staff scheduling and development of decision support systems (DSS). Discrete Event Simulation (DES), Agent Based Simulation (ABS) and System Dynamics are the main simulation methods that have been used for healthcare systems' modelling and analysis [2]. Although each of these methods has its own capabilities, they exhibit some limitations [3]. Table 1 summaries some of the capabilities and limitations of DES and ABS methods in healthcare applications.
Recently, several hybrid/integrated simulation models have been introduced. In such approach, multiple simulation methods are combined in one model. This combination/ integration of individual methods enables the symbiotic realization of the strengths of individual methods, while reducing their limitations [4].
Chahal and Eldabi [5], [6] identified three different formats for the integration between DES and SD: Hierarchical format (data passes between two distinct paradigms), Process–environment format (two distinct paradigms, ...

However, both methods together may be capable of capturing these details. In this paper, a framework for a novel DES–ABS hybrid approach for modeling healthcare systems is proposed with the aim to enable modeling of the complexity of healthcare systems considering the concepts of flows and queues, and also humans' decisions and interactions. Then, a case study for one of the famous radiology centers in Alexandria, Egypt is
