Question: Stage A 20 cars per hour Initial set up time of 20 minute when changing the car model or size Stage B 20 cars per
Stage A 20 cars per hour
Initial set up time of 20 minute when changing the car model or size
Stage B 20 cars per hour
Must be shut down for maintenance and cleaning for 30 minute after every 90 minute of operation
Stage C 18 cars per hour
More customization, but no setups
PART A Single car model
Stage A is already set up How many cars can be produced by the system in an 8-hour shift? How much idle time is there in this stage during such a shift? Which stage will you add capacity to? And by how much? Why?
Part B - Buffer or reduce set up time option
If you add storage buffer it will cost 5K per car. If you add the buffer(s), how much does the system capacity increase too? How many cars can you now produce per shift?
If you add a reduced setup time.
Stage A 20 min go down to 10min 10K to do this
Stage B 30 min go down to 15min 20k to do this
Would you reduce the setup time?
If so at which stages would you reduce setup time and how much would this add to the system capacity?
Which is the better option. Why?
What if we can do both (i.e. add buffers and reduce setup times) what is the increase to system capacity and at what cost?
If you consider all three options(the first two and the combined option), what is the best solution here?
