Set in a local mall, Jenny’s offers 15-minute haircuts for harried shoppers who do not have time for lengthy appointments. To ensure that the clients are in and out quickly, she schedules her 5 employees based on expected client traffic. Each of the employees is paid $1200 per month, with part of their pay coming from client tips. Jenny pays rent and overhead costs of $2000 per month on the facility. Because of the quick nature of the service, Jenny doesn’t have time to clean combs in between clients, so she uses a new comb for each customer, at a cost of $0.55 each. She also provides shampoo and conditioner for each client at a cost of $0.95 per client. The average price for a haircut is $12. Jenny pays herself $5000 per month.A 20,000-seat college football stadium is used 12 times for games, concerts, and graduation ceremonies.

- Recreate the given figure for a call center that wants to achieve a 40 percent no hold rate. Suppose that agents only become cost effective (where the revenue they generate exceeds their cost) if they have 90 percent utilization. How large, in terms of number of agents, does the call center need to be to have agents that are generating a positive profit? If mean call time is 5 minutes, what would the arrival rate need to be for 90 percent agent utilization with this many agents?Burkina Faso, a landlocked country in West Africa, has the lowest adult literacy rate in the world (25.3%). Over the past 15 years, the government has focused heavily on improving access to education across the country. Between 2008 and 2015, the primary school completion rate rose from 40% to 60%, and the high school completion rate doubled over the same period from 15% to 30%. Despite these encouraging statistics, children in rural areas, especially girls, continue to have limited access to quality education.

The agency is under a budget and wishes to keep its costs at a minimum. However, hiring student interns is less costly than hiring full-time employees. Accordingly, the agency wishes to hire the maximum number of students without overstaffing. On the average, it takes two interns all summer to research a case. The interns turn their work over to staff attorneys, who prosecute the cases in the fall when the circuit court convenes. The legal staff coordinator has to place his budget request in June of the preceding summer for the number of positions he wishes to maintain. It is therefore impossible for him to know with certainty how many cases will be researched in the following summer. The data from the preceding summers are as follows Year: 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 Cases: 6…
