Discrete Event Simulation Models for CT Examination Queuing in West China Hospital

Table 4

Results of base model comparing with the historical data.

Evaluation indicator	Outputs
	Historical data	Base model	95% confidence interval of mean value
Daily examination quantity	245	246.5	(234.2, 258.8)
The average waiting time of GPs	66.8	64.0	(60.8, 67.2)
The average waiting time of EPs	2.5	2.4	(2.3, 2.5)
The satisfaction rate of GPs	—	35.2%	(38.3%, 42.3%)

Note. In practice, no one measured the satisfaction rate of GPs, so we cannot compare the result obtained from the base model with the historical data.
