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 (i.e., 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 Which step in the process is the bottleneck? ANSWER b. What is the capacity of the process? ANSWER 12. Consider a process that makes high-end boards that get mounted on skateboards. The process starts with a unit cost of $25 for the first unit, i.e., c(1) = 25, and has a learning rate of LR = 0.90. What will be the unit cost for the 64th unit? unit cost 13. Consider a process restringing tennis rackets. The process starts with a unit cost of $15 for the first unit, i.e., c(1) = 15, and a learning rate of LR = 0.85. What will be the unit cost for the 19th unit? unit cost
