Needing the answers to Part A, C, D, and F.

Consider a process consisting of three resources. Assume there exists unlimited demand for the product. Resource 1 has a processing time of 4 minutes per unit. Resource 2 has a processing time of 3 minutes per unit. Resource 3 has a processing time of 2 minutes per unit. All three resources are staffed by one worker and each worker gets paid $11 per hour. Instruction: "Round "cost of direct labor" and "target manpower" to 2 decimal places. Round average labor utilization" percent and "takt time" to 2 decimal places a. What is the cost of direct labor? $ 1.65 per unit b. What is the labor content? 9minutes per unit How much idle time does the worker at resource 3 have per unit? 7 minutes per unit d. What is the average labor utilization? 45.00 percent Assume the demand rate is 15 units per hour. What is the takt time? minutes per unit Assume the demand rate is 15 units per hour. What is the target manpower? 3.00 minutes per unit

Explanation / Answer

Key here is product demand is unlimited.

a) Bottleneck is resource 1 taking max time. In this cae its 4 minute per unit.

So max prodcution per unit = 60 / 4 = 15 units

So cost per unit for 3 resources = (11 / 15) * 3 = $ 2.2 per unit

f ) For demand rate of 15 units per hour, target manpower is 60 / 4 = 15 minutes per hr.

c) Idle time at resource 3 is 2 minutes. Since resource 1 is bottleneck and has to work continuously, resource 3 has to wait for 2 minutes per unit.

d) Utilization for resource 1 = 100%

Utilization for resource 2 = 3 / 4 = 75%

Utilization for resource 3 = 2 / 4 = 50%

So average utilization = 75%
