PA 5-16 (Static) Consider the Consider the following four-step assembly operation with quality problems. All resources are staffed by one employee. The first resource has a processing time of 5 minutes per unit. The second resource has a processing time of 6 minutes per unit The third resource has a processing time of 3 minutes per unit. With a 30 percent probability, the flow unit coming out of the third resource has to be reworked. In that case, the operations at the first second, and third resources are repeated. You can assume that (a) rework always succeeds (ie, a unit going through the rework loop will always work after the third resource) and (b) the processing times for units in rework are the same as for regular units. The fourth resource has a processing time of 4 minutes per unit. a. Where in the process is the bottleneck? Step 1 Step 2 Step 3 Step 4 ces (Round your answers to 2 decimal places.) b. What is the capacity of the process? good units per hour PA 5-11 (Static) To obtain your first driver's license you must... To obtain your first driver's license, you must successfully complete several activities. First, you must produce the appropriate identification. Then, you must pass a written exam. Finally, you must pass the road exam At each of these steps, 10 percent, 15 percent, and 40 percent of driver's license hopefuls fail to fulfill the step's requirements. You are only allowed to take the written exam if your identification is approved, and you are only allowed to take the road test if you have passed the written exam. Each step takes 5. 3, and 20 minutes, respectively (staff members administering written exams need only set up the applicant at a computer). Currently, the DMV staffs 4 people to process license applications, 2 to administer written exams, and 15 to judge the road exam. DMV staff work 8 hours per day. (a) Where is the bottleneck, according to the current staffing plan? Identification Written exam Road exam good units per day (b) What is the capacity of the process (expressed in approved cases per day)? ces
