allows the chronological order of the events to be
accessed.
Such lists easily accommodate insertion, deletion,
switching of events, etc.
What is the event-scheduling approach? Correct Answer
Concentrate on the events and how they affect the system
state.
Help the simulation evolve over time by keeping track of
every freaking event in increasing order of time of
occurrence.
This is a book keeping hassle.
What is the process-interaction approach? Correct Answer
1. Create customers every once in a while.
2. Process (serve) them, maybe after waiting in line.
3. Dispose of the customers after they're done being
processed.
