Question

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

Answer 1

119 fans

Step-by-step explanation:

The computation of the estimated WIP is shown below:

= Average fans per hour × average hours

where,

Average fans per hour is

= 850 fans ÷ 20 hours

= 42.5 fans

And, the average hours is 2.8

So, the estimated WIP is

= 42.5 × 2.8

= 119 fans

We assume we have to find out the average estimated WIP level
