The Insert tab contains commands related to adding items to a project.

Wizard

  Project Item Wizard opens the Project Item Wizard which provides information about all the analyses that you could add to the project and guides you through any steps required to configure the analysis that you have selected.

Folios

  Weibull++ Standard Folio adds a Weibull++ standard folio to the project for life data analysis. The folio allows you to capture life data (e.g., failure times) from a sample of units and analyze the data based on an underlying life distribution. From the analysis, you can measure the reliability performance of a product over time or make projections about future behavior.

  ALTA Standard Folio adds an ALTA standard folio to the project for accelerated life testing data analysis. The folio allows you to capture life data (e.g., failure times) from a sample of units that are subjected to elevated stress conditions (the elevated stress conditions cause the units to fail more quickly, reducing the test time required to obtain data for a product). You can then analyze the data based on a life-stress relationship model in order to extrapolate a use level pdf, which allows you to obtain reliability predictions about the product at normal operating conditions.

  Warranty adds a warranty data analysis folio to the project. The folio allows you to capture and analyze failure data from fielded products in order to predict future warranty returns (product failures) and plan for warranty fulfillment needs, such as the number of spares to stock.

  Weibull++ Degradation adds a Weibull++ degradation analysis folio to the project. The folio allows you to record the amount or level of degradation of a product over time in order to estimate the point at which the product is expected to fail. The folio uses basic mathematical models to extrapolate failure times from the measurements. The software then analyzes the extrapolated failure times using standard life data analysis in order to obtain reliability predictions about the product.

  ALTA Degradation adds an ALTA degradation analysis folio to the project for accelerated degradation analysis. The folio allows you to record the amount or level of degradation over time for a product that is subjected to elevated stress conditions in order to estimate the point at which the product is expected to fail (the elevated stress conditions accelerate the degradation of the product, reducing the test time required to obtain the measurements). The folio uses basic mathematical models to extrapolate failure times from the measurements. The software then analyzes the extrapolated failure times using accelerated life testing data analysis in order to obtain reliability predictions about the product at normal operating conditions.

  Non-Parametric LDA adds a non-parametric life data analysis (LDA) folio to the project. The folio allows you to capture the life data from a sample of units and analyze the data without assuming an underlying life distribution. This analysis is useful when dealing with unknown failure modes, when there is not enough data to assume a life distribution or when the data set does not fit any life distribution in a satisfactory way. The folio also allows you to perform a standard (parametric) life data analysis on the data set in order to compare the results obtained from both methods and perform further analysis.

  Event Log adds an event log folio to the project. The folio allows you to capture data in an event log format (commonly used in the Machine Tools and other industries) and analyze the information in order to create a reliability model for a piece of equipment. The reliability model can be used to help you understand the performance of the equipment, such as the total system uptime/downtime, or obtain reliability predictions about its future behavior.

  Parametric RDA adds a parametric recurrent event data analysis (RDA) folio to the project. The folio allows you to capture and analyze data obtained from recurring events, as in the case of a repairable system that may fail or be repaired multiple times during its operation life. The folio uses the General Renewal Process (GRP) model to describe the failure behavior of a system over time and obtain estimates such as the cumulative number of failures, mean time between failures (MTBF) and failure intensity.

  Non-Parametric RDA adds a non-parametric recurrent event data analysis (RDA) folio to the project. The folio allows you to capture and analyze data obtained from recurring events, as in the case of a repairable system that may fail or be repaired multiple times during its operation life. The folio uses the mean cumulative function (MCF) to model the reliability performance of a system over time and obtain estimates such as the cumulative number of failures.

Tools

  Diagram adds a reliability block diagram (RBD) to the project. In Weibull++ and ALTA, RBD diagrams are used to graphically represent the failure modes of a product and analyze how each mode contributes to the overall reliability performance of the product.

  Weibull++ SimuMatic opens the Weibull++ SimuMatic Setup window, which allows you to generate several data sets all at once (via the Weibull++  Monte Carlo utility) and automatically perform basic life data analysis on each of the generated data sets. The simulated data could be used in a number of applications such as in the analysis of probabilistic models, risk analysis and in designing reliability tests.

  ALTA SimuMatic opens the ALTA SimuMatic Setup window, which allows you to generate several data sets all at once (via the ALTA Monte Carlo utility) and automatically perform accelerated life testing data analysis on each of the generated data sets. The simulated data could be used in a number of applications such as in the analysis of probabilistic models, risk analysis and in designing reliability tests.

  Test Design opens the Test Design Assistant, which provides tools that help you design, evaluate and compare reliability demonstration tests based on the number of failures (pass/fail tests) or the time of failure.

  Target Reliability adds a target reliability estimator folio to the project. The folio generates plots to help you select a reliability goal that will minimize cost, maximize profit and maximize the return on an investment.

  Life Comparison adds a life comparison folio to the project. The folio allows you to compare two data sets to determine whether the lives of the units in the first data set will outlast the lives of the units in the second.

  Stress-Strength Comparison adds a stress-strength comparison folio to the project. The folio allows you to compare two data sets to determine the probability of failure based on the probability of stress exceeding strength.

  Equation Fit Solver adds a non-linear equation fit solver folio to the project. The folio allows you to estimate the parameters of any user-defined non-linear equation. This gives you the flexibility to perform simple parameter estimation on statistical models other than the life distributions and life-stress relationship models available in Weibull++ and ALTA.

  ALTA Test Plan adds an ALTA test plan folio to the project. The folio helps you design a test plan for accelerated life data testing analysis. Based on information you provide, the test plan will include recommendations for stress levels and the number of units to be tested at each stress level.

  ALTA Stress Profile adds an ALTA stress profile folio to the project. Stress profiles describe how stress levels will vary with time and can be used to describe the stress conditions during testing when you analyze the data using the cumulative damage model in the ALTA standard folio.

  Maintenance Planning adds a maintenance planning folio to the project. The folio generates a cost vs. time plot that helps you determine the cost-effective time to replace aged components.

Reports and Plots

  Analysis Workbook opens the Analysis Workbook Wizard, which allows you to create customized plots and graphs to display the results of your analyses. This reporting tool is useful for creating spreadsheet-type reports that include absolute references to specific analyses.

  Word Report Template opens a Word report template, which allows you to create customized plots and graphs that use functionality that is similar to a Microsoft Word document. You may prefer to use this reporting tool if you want to have a more polished, professional looking report that can easily be reused just by changing the referenced data sources.   

  Overlay Plot adds an overlay plot to the project allowing you to display in a single plot results from multiple data sheets. This provides an easy visual method to compare analyses. For example, you may wish to show the reliability plots of two product designs in the same plot or compare a simulation-based data set with actual data obtained from fielded products.

  Side-By-Side Plot adds a side-by-side plot to the project allowing you to display different plots of a single data set all in a single window for easy comparison. In Weibull++, you can select to plot the data set using multiple distributions or plot types. In ALTA, you get a third option to plot the data set using multiple life-stress relationship models.
