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.

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?
