Quick Calculation Pad (QCP)

The Quick Calculation Pad (QCP) provides a convenient way of calculating a variety of useful metrics. You can access the tool by clicking the QCP icon on the Analytical or Simulation page of the diagram control panel.

  or   

The following example shows the QCP for analytical diagrams.

This topic provides a general description of the QCP and how to use it in most analyses. For more focused information about the types of calculations that can be performed for an analytical diagram, see Analytical Quick Calculation Pad. For information about the types of calculations available for simulation diagrams and phase diagrams, see Simulation Quick Calculation Pad. For information about the types of calculations available for Markov diagrams, see Markov Quick Calculation Pad.

How to Use the QCP

To use the QCP, do the following:

Confidence bounds

If you select Both One-Sided, the QCP will calculate both the lower one-sided bound and the upper one-sided bound.

Note: Confidence bounds are available only in cases where all blocks that can fail in the analytical diagram use models that have Fisher matrix bounds. To have Fisher matrix bounds, a model must have been created by publishing from a data source, such as a Weibull++ or ALTA data sheet, that was calculated using Fisher matrix bounds. Additionally, bounds are not available if the diagram has containers, subdiagrams or mirrored blocks, or if any block uses the cumulative damage model.
