Reliability Metrics, Plots and
Custom Analyses
Get Useful Reliability
Metrics in a Mouse-Click with the Quick Calculation Pad
ReliaSoft's Quick Calculation Pad (QCP) provides a quick, easy and
accurate way for you to obtain exact results for the most frequently
asked reliability questions, such as the mean life, warranty time
and BX information. All QCP results can be displayed and manipulated
in ALTA’s Result Panel and flexible
general spreadsheet. In addition, you have the option to keep
the QCP open while you return to the current Data Folio to make
modifications or change data sets and then continue to perform QCP
calculations.
Unparalleled Plots and
Graphs to Showcase Your Analyses!
ALTA
continues to offer unparalleled plots and graphics capabilities. With
the click of a button, you can create a wide variety of plots,
including:
- Probability plots, which
represent the product’s behavior under each of the accelerated stress
conditions and the expected behavior under normal use conditions.
- Reliability, Unreliability and
Failure Rate plots, which show key metrics vs. time
(2-dimensional) or vs. time and stress (3-dimensional).
- pdf plots, which
provide a good way to visualize the characteristics of the use-level
distribution (2D and 3D plots are available).
- Life vs. Stress plots, which
show applicable life measures (e.g. Eta, Mean Life, etc.) plotted
against stress (2D) or vs. stress and time (3D). In the
two-dimensional plot, you also have the option to superimpose the pdf
for each stress level.
- Standard Deviation (Std) and
Acceleration Factor (AF) vs. Stress plots, which provide
information about the spread of the data (Std) and the acceleration
factor (AF) at each stress level.
- Residuals plots, which can be
used to determine the adequacy of the model for a particular data set.
Depending on the analysis, three types of plots are available:
Standardized Residuals, Cox-Snell Residuals and Standardized vs.
Fitted Values.
Plotting
features include:
-
Option
to plot some or all stress levels in a single plot.
-
Option
to specify a stress as varied while the others are held constant in
life vs. stress and other plots.
-
Option
to represent suspension data points on plots as well as the number in
a group for grouped data.
-
Option
to set and show the target reliability on plots.
The Plot Setup allows you to
configure the appearance of plot output and the software also provides a
Chart Wizard to create your own custom charts. All plot graphics
are metafiles that can be pasted or inserted into other reports and
presentations.
The MultiPlot makes it easy to
compare analyses by automatically plotting the results for multiple
data sets together in the same plot. The Side-by-Side Plots
utility allows you to view (and print) up to twelve plots for a given data set side-by-side. For example, you may
want to show the probability, reliability, pdf and failure rate
plots for a given analysis together in the same window. Alternatively,
you may wish to compare the probability or pdf plots for a given data
set when analyzed with different life-stress models or distributions.
Simply select the combination that meets your analysis/reporting needs.
In addition, you can use ReliaSoft’s
3D Plot utility to generate a variety of three-dimensional plots.
View, print or even modify three-dimensional likelihood function, pdf,
failure rate, reliability and unreliability plots in moments!
ReliaSoft Draw: A Completely
Integrated Graphics Editor
Editing and annotating your plots has never been easier! With RS Draw, you
can take complete graphical control of all of the plots and graphics you
create. This includes the ability to insert text, draw objects, mark particular
points or paste other pictures into your plots. You can then save them as
Windows metafile graphics for easy use in other Windows applications.
Spreadsheets and
Template-Based Report Generator for Custom Analyses and Reports
ALTA's General Spreadsheets
are used just like an Excel® worksheet to perform your own customized
analyses. These spreadsheets provide complete in-cell formula support,
cell references, over 200 built-in functions and integration with the
Function Wizard and the Chart Wizard. You can use the
Function Wizard to insert a wide array of calculated results based on
your inputs and, when applicable, a referenced Data Sheet. Available
results range from basic math/statistical functions to common
reliability analysis results, and much more. Now
in Version 7, this works more like Excel functions, with the
ability to type functions directly into cells and results that are
updated automatically when the inputs change. The Chart Wizard leads you
through a step-by-step process to create and configure your own custom
charts/plots based on a selected data set.
The Report Wizard utility allows
you to design print-ready reports to showcase your analyses. The
template feature makes it easy to apply the same report format to
different analyses. This utility has been revised and enhanced in
Version 7 and now provides an intuitive spreadsheet-based interface for
creating and formatting reports.
