Floor-On, Ltd., operates a line that produces self-adhesive tiles. This line consists of single-machine tations and is almost balanced i.e, station rates are nearly equal). A manufacturing engineer has estimated the bottleneck rate of the line to be 2,000 cases per 16-hour day and the raw process time to be 30 minutes, The line has averaged 1,600 cases per day, and cycle time has averaged 4 hours.
a) What would you estimate average wip level to be?
b) How does this performance compare to the practical worst case?
