a. Suppose that your current batch size is 1,000. Calculate your effective capacity
b. For competitive reasons, you decide that you want to reduce the batch size in order to better respond to the demand fluctuations and cut down on inventory. At the same time, you decide that you need to maintain a capacity cushion of 10% in order to meet preventive maintenance schedules. Calculate the smallest batch size you can choose and still meet the average demand requirements of 5000 units/day
c. The production manager at your Company decided to cut all batch sizes to ¼ their original quantity. After 2 weeks the results are in, inventories are way up and all deliveries have been late! Briefly explain why the production manager’s scheme didn’t work as planned.
4. (15 points) “Action Masters”
a. Identify the bottleneck and calculate the overall capacity of this system
b. The Toy manufacturer has resources to support a single inspection station in the production process. Where should they put the station? Circle the best answer.
I. After the bottleneck, “Treat bottleneck output like ‘gold’”
II. After final assembly, “Treat final output ‘like gold’”
III. Before the bottleneck, “Keep the bottleneck working on good parts”
IV. Before the first stage, “Keep the system working on good parts”
c. Suppose that the toy manufacturer improves the process, so the capacity of Step B is doubled. Identify the bottleneck and calculate the overall capacity of the improved system.
5. (15 points) “Inoculation system”
A single public health worker is inoculating children against measles at a local clinic. An average of 6 children per hour are expected to arrive according to a Poisson Distribution. He serves the children at a rate of 8 per hour. Assume that the service-time distribution is approximately exponential.
a) (10 points) For the ‘inoculation system’, find:
i) the load factor and utilization of the health worker
ii) the average time spent by a child in the system
iii) the average number of children in the system
iv) the average number of children in line
b) (5 points) At what rate must children be served in order to reduce the average time spent in the system to 15 min.?
