The simplest manufacturing situation has a single machine
in a single station. The model is shown schematically
in Fig. 3.
Figure 3. Single Machine Station
The Extend model for the single machine
case is shown in Figure. 4.
Figure 4. Extend Model for the Single Machine
System
The Single Machine model is similar to
the model in Figure 2, except here we use a single server.
The interarrival time has an exponential distribution
with mean 5, while the service time has an exponential
distribution with mean 4. The Histogram block connected
to the W output of the queue block collects statistics
on the waiting time. Figure 5 shows the histogram constructed
from a single run. This particular simulation was set
to terminate at 250 time units.
