7) Calculate the efficiency and utilization for the following problems: a. A houseboat builder has the facilities, labor and supplies to build 10 boats in a month. For January, he planned to build eight boats. His actual production was seven. b. A trailer manufacturer developed her process to be able to produce six trailers in a day. For Monday, she scheduled the production of five trailers, but her production operation produced four. c. An ice cream manufacturing company designed their production operations to make 21,600 gallons of ice cream in a 30-day month (30 gallons per hour). In July, the operation plans to be shut down for three 24-hour periods for the Fourth of July and plans for 12 hours of type-change time over the month. They are planning for no maintenance hours because they scheduled those in June. During the month, they kept this planned schedule exactly, and in addition had 145 hours of equipment breakdowns and 60 hours of quality-related problems.
