Chapter 11, Problem 9P
Question:
9. The Restwell Motel in Orlando, Florida, is preparing an aggregate plan for the upcoming twelve days. The motel has a maximum of 200 rooms, but demand varies during the week. Demand is listed in terms of rooms rented each day. The motel requires one employee, paid S105 per day for each 12 rooms rented on regular time. It can utilize up to 20 percent overtime at time and a half and also can hire part-time workers at S120 per day. Each part-time worker can also clean 12 rooms per day. There is no hiring and layoff cost for the part-time workers. A fractional number of part-time workers (e.g., 3.4 workers) can be employed since less than a full day of employment is possible for each worker.
- a. Assume a steady regular workforce of 10 employees, 20 percent overtime when needed, and the balance of demand met by part-time workers. How much does this strategy cost over the 12-day planning horizon. When needed to meet demand, assume maximum overtime is used before part-time workers are hired.
- b. What is the total cost over the 12-day planning horizon if the regular workforce of 10 employees and only part-time workers are used? No overtime is used?

The Clothing Shack is an online retailer of men's, women's, and children's clothing. The company has
been in business for four years and makes a modest profit from its online sales. However, in an effort
to compete successfully against online retailing heavyweights, the Clothing Shack's marketing
director, Makaya O'Neil, has determined that the Clothing Shack's marketing information systems
need improvement.
Ms. O'Neil feels that the Clothing Shack should begin sending out catalogs to its customers, keep
better track of its customer's buying habits, perform target marketing, and provide a more
personalized shopping experience for its customers. Several months ago, Ms. O'Neil submitted a
systems service request (SSR) to the Clothing Shack's steering committee. The committee
unanimously approved this project. You were assigned to the project at that time and have since
helped your project team successfully complete the project initiation and planning phase. Your team

- Each machine costs $3 Million. Building the room with all its attendant safety protection and other ancillary costs increases the spending by an additional $2.0 million dollars per MRI suite. Each machine can perform 2000 scans per year. Each reading of an MRI scan by a radiologist, along with other per-scan-related costs, is $500 per scan. The machine will last five years. Don’t worry about discount rates for this problem Graph the total costs over 5 years as a function of sales for 0-3000 patients annually. Hint: you may need to add a second MRI at some point. Suppose that you want to make a profit of $500 per scan at a target volume of 1000 patients per year, and you purchase only one machine.
