Background: The aim of this article is to develop a metamodel using a simulation-based approach to analyze the performance of the Patients’ Queue system of the emergency department.
Methods: In this study, the variables affecting on resource efficiency were identified and analyzed using inferential statistics and then one-way ANOVA to estimate the effects of effective factors. Furthermore, the ED performance was simulated using Visual Paradigm software. Then, the results obtained from the implementation of the simulation model were considered as the input of the experimental design.
Results: The findings indicate that the non-linear regression model could predict the length of the queue. Also, this model, according to acceptable parameters, can be used to predict the dependent variable.
Conclusion: Therefore, the minimum value of queue length based on the developed model is obtained when the minimum length of the queue is obtained when the number of ED secretaries is at a high level and the number of paramedics and nurses is at a low level.
