Excel Assignment: Truck Scheduling

Mal-Wart truck fleet hires temporary drivers for four- and eight-hour shift during holiday sales season. Four-hour shifts start at 6am, noon, and 2pm; eight-hour shifts start at 6am, 8am, noon, and 2pm.

The number of drivers needed varies during the day. The table below shows the minimum number of drivers that are needed each two-hour time block throughout the day. (For example, Mal-Wart needs 37 drivers from 8am to 10am.)

A driver’s pay depends on the hours worked. A driver gets paid $10 per day, plus $7 per hour worked, plus a $1 hour premium for each hour worked before 8am or after 6pm. Mal-Wart would like to pay as little as possible while having enough drivers at all times.
