15 2 p (Chapter 4: Process Improvement) Consider a process consisting of three resources. Assume the demand rate is 8 units/hour. The process activities are always performed in the following sequence. Resource 1 has a processing time of 5 minutes per unit. Resource 2 has a processing time of 4 minutes per unit. Resource 3 has a processing time of 6 minutes per unit. Resource 1 is staffed by worker A and A's wage rate is $13 per hour. Resource 2 is staffed by worker B and B's wage rate is $13 per hour. Resource 3 is staffed by worker C and C's wage rate is $20 per hour. If one additional worker could be hired, to which resource should this worker be assigned? Calculate the new process capacity in units/hr. O Assign the new worker to Resource 3. The process capacity is 12 units per hour. O Assign the new worker to Resource 3. The process capacity is 10 units per hour. Assign the new worker to Resource 1. The process capacity is 20 units per hour. O Assign the new worker to Resource 2. The process capacity is 15 units per hour. (Chapter 7: Process Interruptions) Cyclone Electronics Inc. manufactures electronic modules for cam manufacturers. It involves three basic operations: etching the circuit boards, soldering components onto each board, and testing the module. The table below lists the required processing times and setup times. There is unlimited space for buffer inventory between these steps. Assume unlimited demand. Process Step Setup time (min) Etching 42 Soldering Testing 32 26 Processing time (min) 0.15 0.27 0.24 With a batch size of 200 modules, where is the bottleneck? What is the approximate process capacity? O Etching: 400 units/hr O Soldering: 140 units/hr Soldering: 222 units/hr O Testing: 250 units/hr (Chapter 3: Process Analysis) Consider a process consisting of three resources. The process activities are always performed in the following sequence. Resource 1 has a processing time of 5 minutes per unit. Resource 2 has a processing time of 4 minutes per unit. Resource 3 has a processing time of 6 minutes per unit. Resource 1 is staffed by worker A and A's wage rate is $13 per hour. Resource 2 is staffed by worker B and B's wage rate is $13 per hour. Resource 3 is staffed by worker C and C's wage rate is $20 per hour. Assume the demand rate is 8 units/hour. There is unlimited space for buffer inventory between the resources. What is the difference in the total time to produce 20 units if the process starts empty and if the process is busy (i.e. with a full system)? O 150 minutes O 48 minutes O 15 minutes O 7.5 minutes (Chapter 4: Process Improvement) Consider a process consisting of three resources. Assume the demand rate is 8 units/hour. The process activities are always performed in the following sequence. Resource 1 has a processing time of 5 minutes per unit. Resource 2 has a processing time of 4 minutes per unit. Resource 3 has a processing time of 6 minutes per unit. Resource 1 is staffed by worker A and A's wage rate is $13 per hour. Resource 2 is staffed by worker B and B's wage rate is $13 per hour. Resource 3 is staffed by worker C and C's wage rate is $20 per hour. 13 To improve the process, we can take 1 minute of processing time from one resource and give it to another resource (so the labor content remains the same), Which among the choices below would increase process capacity. What is the process capacity (units per hour)? Take 1 minute from Resource 2 and give it to Resource 3. The new process capacity is 8.6 units/hr. O Take 1 minute from Resource 3 and give it to Resource 2. The process capacity is 12 units/hr. Take 1 minute from Resource 1 and give it to Resource 3. The process capacity is 10 units/hr. Take 1 minute from Resource 1 and give it to Resource 3. The new process capacity is 13.6 units/hr
