Question 1 (2 marks): Answer Problem S7.1 If a plant were designed to produce 7000 hammers per day but is limited to making 6000 hammers per day because of the time needed to change equipment between styles of hammers, what is the utilization? Question 2 (3 Mark): Answer Problem S7.9 A production line at V. J. Sugumarans machine shop has three stations. The first station can process a unit in 10 minutes. The second station has two identical machines, each of which can process a unit in 12 minutes (each unit needs only to be processed on one of the two machine). The third station can process a unit in 8 minutes. Which station is the bottleneck station? Question 3 (4 Marks): The staff-training center at a large regional hospital provides training sessions in CPR to all employees.

Since the training center was first put in use, the program has become more complex, so that 1400 now represents the most employees that can be trained per year. In the past year, 1350 employees were trained. Calculate the efficiency and the utilization of this system. Question 4 (4 marks) Answer Problem S7.17 Markland Manufacturing intends to increase capacity by overcoming a bottleneck operation by adding new equipment. Two vendors have presented proposals. The fixed costs for Proposal A are $50,000, and for proposal B, $70,000. The variable cost for A is $12.00, and for B, $10.00. The revenue generated by each unit is $20.00 a) What is the breakeven point in units for Proposal A? b) What is the breakeven point in units for Proposal B? Group A: Question 5 (5 Mark): A shipment of parts valued at $75,000 needs to be shipped from Tampa, FL, to Chicago, IL. They could be shipped by rail, taking 15 days at a cost of $1,575, or by truck, taking 4 days at a cost of $2,640. The annual holding cost rate for this type of item has been estimated at 22%. What option is more economical? Show your calculations.
