HAL Computer has a printed-circuit board plant that contains a line with two stations. The first station (resist apply) applies a photoresist material to circuit boards. The second station (expose) exposes the boards to ultraviolet light to produce a circuit pattern that is later etched onto the boards. Because the expose operation must take place in a clean room, space for WIP between the two processes is limited to 25 jobs. Capacity calculations show the bottleneck to be expose, which requires an average of 25 minutes to process a job, with an SCV of one. Resist apply requires 21 minutes per job, with an SCV of 0.25. In addition (and not included in the above process times), expose has a mean time to failure (MTTF) of 3,33 hours and a mean time to repair (MTTR) of 10 minutes, while resist apply has an MTTF of 48 hours and an MTTR of 8 hours. Jobs arrive to resist apply with a fair amount of variability, so we assume an arrival SCV c2 a of one. The desired throughput rate is 2.4 jobs per hour. a) can HP make this rate desired? answer with calculations b) what if we assume that have 8 jobs in between the stations? c) what if the time to repair reduce from 8 to 5 hours?
