(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 ir units/hr. Assign the new worker to Resource 1. The process capacity is 20 units per hour. Assign the new worker to Resource 3 . The process capacity is 10 units per hour. Assign the new worker to Resource 3 . The process capacity is 12 units per hour. Assign the new worker to Resource 2. The process capacity is 15 units per hour
