Cara Ryder managers a ski school in a large resort andis trying to develop a schedule for instructors. The instructorsreceive little salary and work just enough to earn room and board.The receive free skiing and spend most of their free time tacklingthe resort’s notorious double black-diamond slopes. Hence, theinstructors work only 4 days a week. One of the lesson packagesoffered at the resort is a 4-day beginner package. Ryder likes tokeep the same instructor with a group over the 4-day period, so sheschedules the instructors for 4 consecutive days and then 3 daysoff. Ryder uses years of experience with demand forecasts providedby management to formulate her instructor requirements for theupcoming month.
