A 15 identical station transfer line presently operates with a line efficiency E=0.25. The ideal cycle time is 1.0 min. The repair operation has special distribution with an average downtime per occurrence = 5 min, and each station has an equal probability of failure. Proportion of downtime (the case when stage 1 is down and stage 2 operates) has special correlation with buffer quantity. h(b) r(4-262) wherer = = It is possible to divide the line into two stages, separating the stages (1-rb2) with buffer of capacity of b. With the given information determine the minimum required value of b that will increase the efficiency from E=0.25 to E=0.45. =
