Textbook Question
Chapter 11, Problem 16P
Refer to Example 3. Suppose that regular-time capacity will be reduced to 440 units in period 3 to accommodate a companywide safety inspection of equipment. What will the additional cost of the optimal plan be as compared to the one shown in Example 3? Assume all costs and quantities are the same as given in Example 3 except for the regular-time output in period 3. Solve by modifying Table 11.6.

An industrial facility employs 1,200 people and they are to eat in three equal 30-
min shifts. Cafeteria plans to use 36 inch square tables and also plan to have a
vending machine area to be used in conjunction with the cafeteria food service.
According to capacity studies they have on hand, a service line that is capable of
serving 75 employees in the first third of each meal shift.
With the above information, how much space should be planned for a full service
food service facility (cafeteria with vending machines, serving lines plus full
kitchen)?

- Cara Ryder manages a ski school in a large resort and is try-ing to develop a schedule for instructors. The instructorsreceive little salary and work just enough to earn room andboard. They receive free skiing and spend most of their freetime tackling the resort’s notorious double black-diamondslopes. Hence, the instructors work only 4 days a week. Oneof the lesson packages offered at the resort is a 4-day begin-ner package. Ryder likes to keep the same instructor with agroup over the 4-day period, so she schedules the instructorsfor 4 consecutive days and then 3 days off. Ryder uses years ofexperience with demand forecasts provided by managementto formulate her instructor requirements for the upcomingmonth.a.
