The Estimate of Confidence Level for Part Dimension and Fits Test
The double(unilateral)index subjection function model for part dimensional test is constructed, the checkout limit range is partitioned by process capability index, then distributing law of measure dimension is used to estimate the confidence level about part dimentional test and fits test by fuzzy theory. Finally an example is given and the proposed method proves to be feasible and valid.
