AccuracyRatio Measurement Decision Risk Analysis Software - Main Screen

Analyze and Control Measurement Decision Risk 
The overall functions and features of AccuracyRatio are accessed from the Main Screen, which includes menu and tool bars, baseline risks, computed risks, and text boxes for entry of identification data and technical data.  Brief descriptions of the screen features and functions are given below.

  

Menu Bar
The Menu bar provides access to a wide variety of program functions and options. The File menu lists options for opening and saving and opening new or existing analysis files, printing analysis reports, running external applications, and importing data from UncertaintyAnalyzer files.   Screen entries can be cut, copied, pasted, or deleted via the Edit menu.

 

Selecting Baseline on the menu opens the Baseline Risk Analysis Screen, which can be used to define maximum false accept and false reject risks for a given application or quality objective.  Selecting Reliability from the menu opens the Reliability Model Worksheet, which is used to model the change in in-tolerance probability with time of measurement and test equipment.  Once the reliability behavior for the subject and/or measuring parameter has been modeled, the in-tolerance probability at any time elapsed since measurement can be calculated using the % In-Tolerance Reference Screen, which is activated by selecting % In-Tol Reference on the menu.

 

Bias and process uncertainty distribution plots can be viewed via the Plots menu.  Screens for setting the preferred report format, screen appearance, choosing between consumer or producer false accept risk, and equivalent accuracy ratio are accessed via the Options menu.  The Guardband Analysis Worksheet and % In-Tolerance Worksheet can also be accessed via the Options menu.  Selecting Tolerance Limits activates the Parameter Bias Uncertainty Worksheet and selecting Uncertainty activates the Measurement Process Uncertainty Worksheet.
 

Tool Bar
The Tool bar provides icons that can be used to access selected options and functions.  A brief description of the associated function or options can be obtained by placing the mouse cursor over the icon of interest.

 

Subject Unit Information
This section of the screen is used to enter information and data for identifying the item to be measured or verified.  Key information includes: manufacturer, model number, description, parameter under analysis, and any additional qualifiers.  

 

The subject parameter tolerances can be entered as two-sided asymmetric, two-sided symmetric, single-sided upper or single-sided lower values.  The value entered in the % In-Tolerance field is the percentage of times that the subject parameter is expected to be found to be in-tolerance when measured.

 

Measuring System Information

This section of the screen is used to enter information and data for identifying the measuring or test equipment (MTE) used to measure or verify the subject parameter. Key information includes: manufacturer, model number, description, parameter under analysis, and any additional qualifiers.  

 

The measuring system tolerances are computed as a linear combination of a fixed offset and % of reading.  The value entered in the % In-Tolerance field is the probability, in percent, that the measuring parameter will be in-tolerance when measuring or verifying the subject parameter.

 

Baseline Risks

This section of the screen displays the false accept risk, the false reject risk, and the accuracy ratio specified for the baseline measurement decision risk scenario. The baseline accuracy ratio is often synonymous with a minimum required accuracy ratio defined by a contract specification or quality assurance document.

 

Computed Risks

This section of the screen displays the false accept risk, the false reject risk, and the equivalent accuracy ratio computed for the measurement or verification under consideration. The equivalent accuracy ratio is the accuracy ratio that, if used in the baseline measurement scenario, would produce the computed false accept and false reject risks.

 

Analysis Reports
Reports are printed by selecting the Print option on the File menu or clicking the print icon on the Toolbar.  This calls up the Print Analysis Screen.
