Question
If you already have a lot of work to do, then you (may) want to reject additional work, leaving only enough work to keep your bottleneck running close to 100% utilization while still getting the jobs done in the specified lead time.
How do you create such a system - a system where the bottleneck is running close to 100% utilization, and the jobs are done in just less than the specified lead time?
- You set the WIP using I = R T, where R is the rate at which jobs arrive (without any being rejected) and T is the specified lead time.Explanation / Answer
Correct answer is option - You set the WIP using I = R T, where jobs are accepted at a rate R equal to the capacity of the bottleneck and T is the total process time across all stations (excluding the queue time).
By this way one can create a system where if the bottleneck is running close to 100% utilization then the jobs are done in just less than the specified lead time because accepted at a rate R equal to the capacity of the bottleneck.
