A 20station transfer line presently operates with a line efficiency

A 20station transfer line presently operates with a line efficiency E = 1/3. The ideal cycle time = 1.0 min. The repair distribution is geometric with an average downtime per occurrence = 8 min, and each station has an equal probability of failure. It is possible to divide the line into two stages with 10 stations each, separating the stages by a storage buffer of capacity b. With the information given, determine the required value of b that will increase the efficiency from E = 1/3 to E = 2/5.
