and the servers have different service times.
Table 9.6 agrees well with a more detailed simulation reported by Lazowska et al. [179]. Illustrating this table, Figure 9.20 shows the effect of increasing the number of workstations on the waiting time at each workstation, and Figure 9.21 shows the occupancy (utilization) of the server CPU.
