A 15-station transfer line is divided into three stages of 4, 5 and 6 stations. The ideal cycle time of each station is Tc = 1.3 min. All stations have the same probability of stopping, p = 0.004. Assume that the downtime is constant when a breakdown occurs, Td = 3.0 min. (a)Compute the line efficiency and production rate for the following buffer capacities: i) b = 0, ii) b = , iii) b = 8, and iv) b = 70 (b)Evaluate the line efficiencies and production rates for the three-stage line in (a) using the geometric repair distribution instead of constant downtime distribution.
