Overview for Allocate Gap Pools

Use Allocate Gap Pools to allocate the mean and variance pools that are associated with the gap distribution. You need to allocate the mean and variance pools to obtain a Z.Bench of 4.5 for the design.

You allocate the mean and variance pools by designating the proportion of these pools you want made up by each of the elements. This allocation results in a new set of means and/or standard deviations.

Minitab then runs through the procedure again, recalculating new statistics based on the new means and standard deviations. The result should now be a Z.Bench of 4.5 for the design.

The final output includes recommended specification limits for each element in the assembly. If you set the specification limits at these values, you can manufacture each element, as well as the entire assembly, with the PPMs that are shown on the graphical output.

You must calculate gap pools before you can allocate gap pools. For more information, go to Overview for Calculate Gap Pools.
