A suburban hotel derives its revenue from its hotel and restaurant operations. The owners are interested in the relationship between the number of rooms occupied on a nightly basis and the revenue per day in the restaurant. Below is a sample of 25 days (Monday through Thursday) from last year showing the restaurant income and number of rooms occupied.

THE PALM OASIS SUITE HOTEL Cody Michlon, manager of the Palm Oasis Suite Hotel in Miami...

THE PALM OASIS SUITE HOTEL

Cody Michlon, manager of the Palm Oasis Suite Hotel in Miami Beach is requesting your help to improve the guest

experience at the hotel. Cody Michlon plans to remodel the front desk to provide a more customer-centric

experience and create an optimal level of staff efficiency and guest service. Historical data of arrivals during the

peak check-in time of 5:00PM to 7:00PM showed that an average of 80 guests arrive each hour. It takes an average

of 3 minutes for the front-desk clerk to register each guest.

Mr. Michlon wants to improve guest service by reducing the length of time that guests spend waiting in line.

CURRENT (PLAN 0): At present, the hotel has five clerks on duty, each with a separate waiting line.

PLAN I. The first proposal would designate one employee as a quick-service clerk for guests registering under

corporate accounts, a market segment that fills about 30% of all occupied rooms. Because corporate

guests are preregistered, the registration takes an average of just 2 minutes. With these guests separated

from the rest of the clientele, the average time for registering a typical guest would climb to 3.4 minutes.

Under this plan non-corporate guests would choose any of the remaining four separate lines.

PLAN II. The second plan is to implement a single-line system. All guests could form a single waiting line to be

served by whichever of five clerks became available. (The only difference between the current scenario

and this proposed Plan II is the line formation – currently it is set up with five separate lines one in

front of each of the clerks, this plan II proposes a single line that wraps around with a corral and the

next guest will go to the next available clerk). This option would require sufficient lobby space for

what could be a substantial queue.

PLAN III. The use of a self-service kiosk for check-ins is the basis for the third proposal. This kiosk would provide

about the same service rate as would a clerk, however, since check-ins are automated the service time

would be a constant 3 minutes. Because initial use of this technology is minimal, Cody estimates that

20% of customers, primarily frequent guests, would be willing to use this machine – hopefully this

percent will increase in the future. Cody would set-up a single queue for customers who prefer human

check-in clerks (the remaining 80% of the customers). This line would be served by only four clerks,

because of the space requirement for the self-serve kiosk and the extra expense of the technology.

PLAN IV. Please provide your suggestion for a “better” queuing system. Be sure to compare your performance

measures to the other plans. Your idea??????
