ProMSA - Measurement Systems Analysis

Application

ProMSA is a program used to support the analysis of measurement systems (MSA - Measurment System Analysis) according to the guidelines of AIAG MSA Manual - 4rd Edition. The manufacturer, Symphony Technologies, has several years of experience in developing applications for, among other things, quality management.

Basic features of the program:

full range of analysis,
graphical presentation of results,
instrument database - scheduling and reporting of analysis dates,
ease of use, user-friendly interface,
natural signaling of compliance and exceedances (green, yellow, red),
scalable analysis layouts (number of operators, parts, repetitions),
instrument list and analysis history in a single database,
export of reports to MS EXCEL spreadsheet format

Scope of analysis:

1) Measurement Systems for Numerical Values (Variable Studies):

Repeatability and Reproducibility (GR&R) Analysis by Range & Average and ANOVA,
Bias Studies,
Linearity (Linearity),
Stability (Stability),

2) Control Systems for Attribute Studies (Attribute Studies, "go/no go"):

"Kappa" method (Cross Tab Method),
Signal Detection Method (Signal Detection Method),
Analytic Method & GPC.

Repeatability and Reproducibility Analysis (GR&R);

Mean and Variance method (so-called Ford Type-2),
ANOVA method,
Long-term stability: the Xśr-R chart,
Graphical analysis: interaction plot, scatter plot (part-operator), waveform plot by part / by operator, scatter component (variance) shares plot,
components of scatter (EV, AV, PV, R&R, TV),
variance components (Percentage Contribution),
signal to noise ratio (Signal to Noise Ratio),
resolution index (ndc),
ANOVA table,
%R&R, %EV, %AV, %PV ratios for different reference quantities.

Bias Study;

estimation of bias,
assessment of the significance of bias (test-t),
color signaling of compliance,
histogram.

Linearity Analysis;

Estimation of bias and scatter for different values of the measurand within the measuring range of the instrument,
regression analysis (confidence intervals),
Goodness of Fit calculations,
color signaling of compliance with requirements.

Stability Analysis;

Stability monitoring with Xśr-R card,
sample size by user selection,
analysis using rules (SPC) Western Electric,
color signaling of compliance with requirements (exceeding control limits, trends).

R&R analysis for attributive properties (Cross Tab Methods);

Attributive parameter control system analysis function with interface for entering evaluation results and lists of reference quantities,
analysis using parameter: Cohen`s kappa,
calculation of the efficiency of the measurement system,
indicators for the number of false alarms.
