Question 5

The Peeps factory can be described as a three step process consisting of Mixing,Forming,and Packaging.Peeps are made in batches of 1000 and have a daily demand of 75,000 units during what the plant manager likes to call "the Peep season." Mixing has a cycle time of .02 seconds with a setup time of 30 seconds;Forming has a setup time of 24 seconds and a cycle time of .03 seconds,and Packaging has a setup time of 15 seconds with a cycle time of .04 seconds.Each process step is handled by one operator,who is available for 8 hours a day.What is the process bottleneck if each process step is assumed to have 100% uptime?

Accepted Answer

The answer of The Peeps factory can be described as...

Question 16

Champion Cooling Company uses a kanban system at their location in the Oklahoma City Metroplex.The daily demand for fans is 2000 and management insists on using an alpha level of 0.1.They use containers that hold 20 items and takes 0.04 of a day to process.It takes 0.07 of a day to get a container filled and for it to wait during its cycle.How many containers should they use? If they use the nearest integer value number of containers,what is the actual system alpha?

Accepted Answer

k = @#IMG-DLM& = @#IMG-DLM& = 12.1 → 12 containers
