Answer 1

4.

S1: Processing time = 10 minutes
S2: Processing time = 10+10 = 20 minutes
S3: Processing time = 25+15 = 40 minutes

So, capacity = 60 / Max(10, 20, 40) = 60/40 = 1.5 per hr.

Flow rate = Min{Demand, Capacity} = Capacity = 1.5 per hr. (since the demand is unlimited)

Cost of direct labor = Total wages paid per hr. / Flow rate = 3*25 / 1.5 = $50 per guest

5.

S1: Processing time = 10 minutes
S2: Processing time = 25+10 = 35 minutes
S3: Processing time = 25+5 = 30 minutes

So, capacity = 60 / Max(10, 35, 30) = 60/35 per hr.

Flow rate = Min{Demand, Capacity} = Capacity = 60/35 per hr. (since the demand is unlimited)

Cost of direct labor = Total wages paid per hr. / Flow rate = 3*15 / (60/35) = $26.25 per guest
