Problem 13-09 (Algorithmic)
Myrtle Air Express decided to offer direct service from Cleveland to Myrtle Beach. Management must decide between a full-price service using the company’s new fleet of jet aircraft and a discount service using smaller capacity commuter planes. It is clear that the best choice depends on the market reaction to the service Myrtle Air offers. Management developed estimates of the contribution to profit for each type of service based upon two possible levels of demand for service to Myrtle Beach: strong and weak. The following table shows the estimated quarterly profits (in thousands of dollars):
| Demand for Service | ||
| Service | Strong | Weak |
| Full price | $1380 | -$580 |
| Discount | $980 | $460 |
| Optimistic approach | Full price service |
| Conservative approach | Discount service |
| Minimax regret approach | Discount service |

QUESTION 1 [25%]. An orthopedic clinic takes appointments between 8:00 and 11:30 a.m. and between 1:00 and 3:30 p.m. and is operational 234 days per year. The clinic receives 24,903 visits annually. Because patient visits involve more than just a visit with the MD, the clinic flow is not a simple in-and-out process. Patients are subjected to a multiple-line queuing system. The first step is patient registration. Four registration clerks are able to register an average of 5.5 patients per hour. Registration includes co-pay collection, insurance and referral verification, and updating demographics in the computer information system. Although the clerical staff have other duties at the end of the day, their only responsibility for this six-hour span is to register patients. The second step is nurse check-in, in which six nurses spend an average of ten minutes with each patient. The average time a patient is with one of the seven MDs is twenty-four minutes. Arrivals follow a Poisson distribution, with a mean of 15 for all steps.
For each individual process (registration, nurse check-in, and MD visit), compute the following performance metrics using the Excel queuing template:
1. a Arrival and service rates
1.b Average number of patients in a queue
1.c Average number of patients in the system
1.d Probability of idle time
1.e System utilization rate

Jessica’s Catering Service bakes and delivers lasagnas to parties and group meetings. In a typical week, Jessica has around 40 orders. Each order involves a specific amount of the required lasagna in pounds. A small group would need about 20 pounds, whereas a large group would need almost triple that amount. The following table shows the different customer orders that have come in this week, grouped into eight categories by weight.

15 points: Jessica has an inventory of 100 six-pound trays and 80 ten-pound trays. Although she appears to have enough capacity in her trays, she would like to plan her orders so that the amount of excess lasagna is kept to a minimum.
5 points: How many six-pound trays and ten-pound trays should Jessica use for each of the orders?
