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)?

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.

- 601 Ana Chavarria, front office manager at The Times Hotel, has completed a revenue management semi- nar at Keystone University and is preparing an argu- ment in favor of adopting this concept at The Times Hotel to present to Margaret Chu, the general man- ager. She begins by compiling a history of room occupancy and ADRS, which she hopes will reveal areas in which revenue management could help. She prepares an electronic spreadsheet that lists rooms sold with corresponding room rates and correlates the data to tourism activities in the area. Ana sends an analysis of revenue realized and revenue potential to Ms. Chu for review prior to their discussion After reviewing the analysis, Ms. Chu concludes, "This is just another scam; the industry is slow to adopt this," and disregards the entire report. She knows that occupancy percentage, ADR, and RevPAR are all you need to be efficient today, so why change?
