There is a constant arrival rate of jobs to the line. a. What is the raw processing time, the bottleneck rate of the line and the critical WIP of the line? b. What is the maximum utilization at each station? What must occur so that maximum utilization is achieved? Page 1 of 2 0. Assume that the second station needs rework at that station 10% of the time. What is the bottleneck rate and the maximum utilization at each station now? (1. Draw a schematic of the line in (c) using symbols from class
