combined:  

This program represents a combined simulation where there
is a grocery store clerk with a food delivery belt. Discrete event
routines are used to model inter-arrivals and server (i.e. clerk)
time, and a simple continuous model is used to model a conveyor belt
that operates at precisely 2 feet per time unit (using the differential
equation x' = 2). The belt is 3 feet long. The information on the
queuing routines is found in the 'queuing' subdirectory.

combined2:

This program simulates a "delay differential equation": x' = ax(t-1).
A circular buffer is used to store the delayed state variable values.
One hundred state values are stored per time unit.
