Chapter F, Problem 12P
Question:
• F.14 Refer to the data in Solved Problem F.1, on page 791, which deals with Higgins Plumbing and Heating. Higgins has now collected 100 weeks of data and finds the following distribution for sales:
- a. Assuming that Higgins maintains a constant supply of 8 heaters, simulate the number of stockouts incurred over a 20-week period (using the seventh column of Table F.4).
- b. Conduct this 20-week simulation two more times and compare your answers with those in (a). Did they change significantly? Why or why not?
- c. What is the new expected number of sales per week?

A combination of Mr. Smith's friendly attitude and the absence of a respectable hotel in the nearby vicinity imply that Mr. Smith enjoys sufficient demand at his low fare of $159 per night. John notes that some customers will walk into the hotel requesting a room for that evening and they are willing to pay a high fare of $325 per night. John knows this demand is variable. (In reality, this demand is U(4,9)) He suggests some rooms should be kept unsold to the low-fare customers so that they can serve the high-fare customers. a) To maximize profits with John's plan, what is the booking limit that should be set for low fare customers? b) Mr Smith does not like the idea of John and says “we will sell to everyone who reserves in advance and ignore the walk-in demand."
