The company intends to close all but four stations, because the lower throughput will require less pumping to maintain its momentum.
However, these advantages are at the cost of much increased latency, significantly lower throughput, and decreased redundancy.
They are the easiest type of collection to establish, but suffer from low and unpredictable throughput.
The stable state with low throughput is known as congestive collapse.
Formally, a bottleneck lies on a system's critical path and provides the lowest throughput.
Health centres with a low throughput may have higher average costs than a busy hospital outpatient department.
This causes a slightly longer response time, which leads to a slightly lower throughput (750,000 counts per second instead of 1,000,000).
Proportional fairness would result in lower throughput, but starvation would be avoided.
The batch heater has the lowest throughput, the continuous plant the highest at up to around 500 Tonnes per hour.
This policy is less fair since "expensive" users are given lower throughput than others, but still scheduling starvation is avoided.
