In designing a general service facility, capacity should be such that the target rate of service utilization (ρ), in order to get the best general purpose design, should be
A) less than 0.6 (or 60%), so that your system would be within the zone of service with maximum possible utilization.
B) more than 0.6 (or 60%) so that your system would have a good utilization.
C) about 0.7 (70%) so that your system would be in the zone of service with maximum possible utilization.
D) more than 1.0 (100%) so that the servers are fully utilized, even if the customers had to wait a little.
E) between 0.9 (90%) and 1.0 (100%) so that the utilization of the system is ideal.

The target rate of service utilization (ρ) should be designed to be about 0.7 (70%) so that the system would be in the zone of service with maximum possible utilization. This is because when ρ = 0.7, it is in the range of 0.6 to 0.9, which is considered the optimal utilization range. In this range, the system is busy enough to be efficient but not too busy that it reaches the maximum capacity limit or causes customer dissatisfaction due to long wait times.
