TECHNOLOGY OVERVIEW

Bias (Multiple Parts, One Equipment, Multiple Appraisers)

The BIS.Net Team BIS.Net Team

This model identifies bias inconsistency over different parts, without regard to linearity.

For this type of study each appraiser must test the same part at least twice. At least two parts must be measured, and all appraisers must test the same number of parts the same number of times. Each part has a different Reference value which appears in the first column

An example of input is shown below.

The BIS.Net MSA APP provides the following output. A dartboard to visualize reproducibility and repeatability and overall bias. A Reproducibility Chart to identify reproducibility problems by appraiser. A probability plot to conform normality. An interaction chart to visualize interactions. An ANOVA, Confidence Interval and Performance table to quantify reproducibility, repeatability and bias inconsistancy
