Problem : In this section, we describe the example system and decide what we'd like to know

about its behavior and performance. Since a lot of simulation models involve waiting lines or

queues as building blocks, we'll start with a very simple case of such a model representing a

portion of a manufacturing facility."Blank" parts arrive to a drilling center, are processed by a

single drill press, and then leave; see Figure $1.$ If a part arrives and finds the drill press idle, its

processing at the drill press starts right away; otherwise, it waits in a first$-$in$,$ first$-$out $($FIFO$)$

queue. This is the logical structure of the model. The system starts at time $0$ minutes with no

parts present and the drill press idle. This empty$-$and$-$idle assumption would be realistic if the

system starts afresh each morning. We've decided that the simulation will stop at exactly time

$20$ minutes
