30,000-seat college football stadium is used 18 times for games, concerts, and graduation ceremonies. Each event averages four hours and assumes the stadium is full for each event. The stadium is available 365 days a year from 6 am to midnight. What is stadium (seat) utilization? Can you think of one or two other assets that have such low resource utilization

A toy firm produces drums sequentially on three machines- A, B, and C- with cycle times of three, four, and six minutes, respectively. a) Determine the optimum efficiency and output rates for adding one, two... six more machines b) Assume now that two identical lines are operating, each with machines A, B, and C. If new machines can be shared between the lines, how should one, two, and then three new machines be added? What are the resulting efficiencies and outputs of the two lines? Is it always best to equally share extra machines between the two lines?

A work cell is required to make 100 computerized diagnostic assemblies (for installation into hybrid automobiles) each day. The cell currently works an eight hour shift, of which seven hours is available for productive work. These assemblies require five operations, with times of 1.5, 1.8, 1.4, 1.5, and 1.9 minutes each. What is takt time for this cell? How many workers will be needed?

A retail catalog operation employs a bank of six telephone operators who process orders using computer terminals. When a terminal breaks down, it must be disconnected and taken to a nearby electronic repair shop, where it is repaired. The mean time between terminal breakdowns is six working days, and the mean time required to repair a terminal is two working days (both exponentially distributed). As a result of lost sales, it costs the mail-order operation an estimated $50 per day in lost profits each day a terminal is out for repair. The company pays the electronics repair shop $3000 per year on a service agreement to repair the terminals. The company is considering the possibility of signing a new service agreement with another electronics repair shop that will provide subsitutute terminals while the broken ones are at the repair shop. However, the new service agreement would cost the mail-order operation $15,000 per year. Assuming that there are 250 working days in a year, determine…

Knott's Industries manufactures standard and super premium backyard swing sets. Currently it has four identical swing-set-making machines, which are operated 275 days per year and 8 hours each day. A capacity cushion of 20 percent is desired. The following information is also known Annual Demand Standard Processing Time Average Lot Size Standard Setup Time per Lot a. Does Knott's have sufficient capacity to meet annual demand? Knott's does Standard Model 20,000 5min 50 30 min Super Premium Model 10,000 17 min 30 45 min have sufficient capacity to meet annual demand because 3 machines are needed. (Enter your response rounded up to the next whole number.) b. If Knott's was able to reduce the setup time for the Super Premium Model from 45 minutes to 30 minutes, would there be enough current capacity to produce 20,000 units of each type of swing set? If Knott's was able to reduce the setup time for the Super Premium Model from 45 minutes to 30 minutes, there would not be enough capacity to…

There are six workers, one at each of the six stations (A-F). They begin their workday at 8:00a.m. and work steadily until 4:00 pm. (They are replaced with other workers for breaks and lunches, but the production is not slowed or stopped during these times.) Their hourly wage rate is $25 per hour. You can assume unlimited demand. What is the average labor utilization (you can ignore any start-up or empty system effects) of the six workers? Please give your answer in decimal form (e.g. 0.5 for 50% utilization).

A company operates 8 hours per shift, two shifts per day, five days a week with 12 hours maintenance per week and other downtime of 2 hours per week. What is the effective capacity in hours per week? Moving to the
