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. The fourth resource has a processing time of 4 minutes per unit. Note: You may assume that: demand is one unit per hour the standard processing times for units in rework are the same as for regular units. rework processing times at the first three steps are the double the standard processing times at each step (because a rework item will go through first three steps twice), and rework always succeeds (l.e., a unit going through the rework loop will always work after the third resource) (b) What is the total workload (in minutes per unit) for each resource and the workload (in minutes per unit) for each rework unit and each 'good' unit for each of the resources (steps)? Demand for Good Units Demand for Rework Units Total Demand Resource [minutes per time unit) [minutes per time unit) [minutes per time unit) [min 1 2 3 4 (Round your answers to whole numbers) Hint: You should suppose that the flow unit is 'minutes of work and, since each hour has 60 minutes, our available time is 60 minutes per hour, which is also the capacity for each resource
