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.
