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.

Question 6 options:
1)
Climate involves statistics (e.g., long-term averages) but weather considers conditions at a particular time and place (e.g., one week of this summer).
2)
The current weather at a location can be characterized by a single measurement, but climate requires many years of measurements (typically around 30) to characterize.
3)
Both weather and climate can vary regionally (e.g., from one side of a mountain range to another).
4)
Climate only refers to temperatures, but weather also includes other factors like wind, rain, and snow.
