Nurses must start work at the beginning of one of the four-hour shifts (starting as early as 12 am midnight or as late as 8pm evening) and work for eight hours. Nurses who begin working at 8 pm will work until 4 am the next morning.
Formulate and solve the nurse-scheduling problem so as to minimize excess stagging while satisfying minimum staffing requrements.
What is the value of total excess staffing?
Using the FCFS rule for scheduling, the sequence is
