Models
A company is open from 7AM until 11PM each day of the week. Each of its workers must work 5 consecutive days, and each day worked, he/she must work 4 consecutive hours, then have an hour off, and then work 4 more consecutive hours. The model assumes that the hourly schedule for a given worker is the same each day worked. The problem is basically to hire as few workers as possible, and to schedule them appropriately, so that there are enough on hand to meet the daily/hourly requirements.
