Q: Jackson Sheds has four different warehouse configurations under study, ranging from four warehouses to seven warehouses (only integer values). Each warehouse has a capacity of 200 units and costs $200 to maintain over the course of a year. Demand can range from 1,000 units per year up to 2,000 units in increments of 250 units.

Q: The VP of Finance studied the printing costs at the university and knew it was time for bold, decisive action. The annual fixed cost of printing at the school was $850,000 and the per-page cost was one cent. Fortunately, his brother-in-law happened to own a company that would lease the printers to the university for only $600,000. The only issue to be decided was what the per-page cost would be for the leased printers. On average, the university had been printing about 10,000,000 pages per year. What would a break-even per-page printing cost be given the average printing volume?

Q: The single milling machine at Fred's Manufacturing was severely overloaded last year. The plant operates 8 hours per day, 5 days per week, and 50 weeks per year. Management prefers a capacity cushion of 20 percent. Two major types of products are routed through the milling machine. The annual demand for product A is 4,000 units and 3,000 units for product B. The batch size for A is 20 units and 30 units for B. The standard processing time for A is 0.5 hours/unit and 0.8 for B. The standard setup time for product A is 2 hours and 8 hours for product B. How many new milling machines are required if Fred's does not resort to any short-term capacity options?

Q: Refer to the bank process model. The bank's process improvement group has developed a number of process and technology changes that will improve the Teller's process rate per customer from a mean of 3.0 minutes to 2.5 minutes (standard deviation remains at 0.5 minutes). The Bank Manager wants to determine if the improved process rate, along with the special promotion for new customers, will allow the "arrive and immediately leave" rate and average customer wait time in line achieved to still be met (12% balk rate, 9.95 minutes in line). If so, the manager will implement the process and technology changes and allow the special promotion to proceed. Using SimQuick, estimate the new arrive and immediately leave rate and average time in line. What decision should the manager make?

Q: Walter White must satisfy an annual demand of 50,000 pounds per year. The setup cost for each batch is $6,500 and once the setup is complete, the product may be produced at the rate of 1800 pounds per day.

Q: SimQuick is to be used to simulate the following bank process: Customers arrive at the Entrance Door of the bank with an average time between arrivals of 2.5 minutes. The Line Buffer holds 6 customers. If a customer arrives and the buffer line is filled, the customer leaves. The Work Station Teller's processing time per customer is normally distributed, with a mean of 3.0 minutes and a standard deviation of 0.5 minutes. The Served Customer Buffer in the flowchart is used to count the number of customers processed during the simulation period. A 2-hour period is to be simulated and the simulation should be repeated 30 times. Determine: a) The number of customers served during the 2-hour period; b) The percentage of customers who arrived at the bank and left because the buffer line was full; c) The utilization of the teller (% of time working) during the 2-hour period;
