Prob $4.(20$ pts$)$ Suppose the same $20-$station operation line as described in Prob $2$ were performed on a buffered assembly system with buffer storage between stations that averages $50$ units.$$

a$)$ What is the actual production rate? Can the production quota of $2,500$ units per eight$-$hour shift be met? $(8$ pts$)$

b$)$ What is the throughput time? $(8$ pts$)$

c$)$ Compare the buffered line with the un$-$buffered line and comment on both systems. $(4$ pts$)$
