QUESTION #4
Four delivery trucks are in a queue at a Tool Company with
only one service bay. The trucks are identified by the sequence
in which they arrived at the Company. Assume the time is
10:00 a.m. The table shows the times necessary to unload each
vehicle and the periods when the commodities they contain
are expected in the factory.
Determine the schedules that result for each of the rules SPE,
CR EDD, and FSFC. In each case compute the average tardiness,
the number of tardy jobs, and mean flow time.
