the ceiling fans. This line consists of single-machine stations and is almost balanced (i.e. station rates are nearly equal). A manufacturing engineer has estimated the bottleneck rate of the line to be 1,000 fans per 20-hour day and the raw process time to be 50 minutes. The line has averaged 850 fans per 20-hour day, and the cycle time has averaged 2.8 hours. What would you estimate the WIP level to be?
