The Academic Computing Center provide training to students. Assume that the design capacity of the system is 1900 students per semester and that effective capacity equals 85% of design capacity. If the number of students who actually got their training is 1500, what is the efficiency of the system?

The aggregate operations plan should not be updated after it is determined the first time, but should be followed precisely until the end.

A local bakery uses the chase strategy of aggregate planning. They produced 100 cakes last week.
