The statement is saying that in the subsystem, all ambulances are dedicated to one ED, whereas in the original system, they serve multiple EDs. This means that there are more ambulances available in the subsystem compared to the actual system. While this could affect the accuracy of our approximation method, it should not be a significant issue when there are enough ambulances available.
When there is a sufficient number of ambulances available, our proposed decomposition approach should yield an accurate approximation because the loss probability for ambulance patients would be small. However, if there is a shortage of ambulances in the actual system, our approximation might deviate from the actual situation since we assume that all ambulances only serve one ED in the subsystem. In reality, this could alleviate some of the ambulance shortages.
In summary, while having more dedicated ambulances in the subsystem could affect our approximation method’s accuracy, it should not be a significant issue when enough ambulances are available. The deviation from reality could arise if there is a shortage of ambulances in the actual system.
