SuperSMITH Visual
For Crow-AMSAA Reliability Growth Plots
And Scientific Plotting Software

SuperSMITH® software has a new look in versions 5.0AZ and higher. Fulton Findings LLC, the maker of the world’s first widely used Weibull Engineering software, has moved ahead with a more tightly integrated user interface for SuperSMITH Weibull and SuperSMITH Visual. The new icon layout shown below consolidates common functionality with unique tools for variability modeling, trend analysis, and forecasting. The familiar data grid (data input and data edit) and results box (plots and reports) remain virtually unchanged. Changes involve integration of the larger-sized icons with associated drop-down menus in a simplified pattern. All previous functionality is retained with new functionality added in specialized areas such as Abernethy Risk, Accelerated Testing, Barringer Process Reliability, and Monte Carlo Simulation.

SuperSMITH Visual (SSV) is a Windows based scientific plotting software which acts as a plotting engine for other Fulton Findings software and is compliant with Section 508 of the Rehabilitation Act of 1973. SuperSMITH Visual assists in analyzing data used for making reliability improvements including reliability growth plots known as:
            Duane plots,
            Duane-AMSAA plots,
            Crow-AMSAA plots, 
            Crow/AMSAA plots,
            C-A plots, and
            C/A plots.

SuperSMITH Visual operates in a Windows 95,Windows NT, Windows 2000, Windows XP, Windows Vista, Windows 7 thru 10 (32 bit and 64 bit) operating environment.  SuperSMITH software will not run on Windows RT version, nor will it run on Windows 8 phones because they have different chip and instruction codes. 

SuperSMITH Weibull also runs on Microsoft’s Surface Pro tablets, Toshiba Encore table, and many also run on Hewlett Packard’s Stream 7.

Price list for the software also provide for volume discounts.  Upgrade installation hints are available.

View the software revision list below.

Three software training aids are available:

1.     PlayTIME is the home study tutorial used for Weibull Analysis training classes by Dr. Abernethy and Wes Fulton.  It is terse but covers most software functions.

2.     The SuperSMITH Weibull and SuperSMITH Visual Training Manual is used for the 1.5 day SuperSMITH Weibull and SuperSMITH Visual hands-on training sessions.  It contains many more detailed explanations along with questions/answers with many hints of how to do the analysis.

3.     You can download a short PDF file that shows excerpts from pre-version 5.0AX of the software Training Manual.  A similar short PDF file for 5.0AX and beyond will assist with getting started with use of the software and how you interpret a Crow-AMSAA plot using SuperSMITH Visual.

SuperSMITH Visual also makes Crow/AMSAA (formerly called Duane/AMSAA) reliability growth curves and with one click of an icon transforms the cumulative failure data into cumulative MTBF with your choice of simple regression, MLE, or MLE-modified as described by IEC 61164.

You can download no-cost demonstration software for evaluation and teaching.  Universities can use the demonstration software to analyze datasets saved from authentic SuperSMITH Visual software as the demo version will handle the authentic file and NOT randomize the data as occurs when you type data into the demonstration software.

For details about each WSV revisions, see the bottom of this page when considering upgrades.

Note: All Fulton Findings software is "stand alone" and provides internal plotting capability as appropriate. SuperSMITH Weibull generate CDF plots but rely on Su

perSMITH Visual for special purpose plots.   An example of a Crow/AMSAA or Duane/AMSAA plot is shown below.

SuperSMITH Visual will import SuperSMITH Weibull files and plot probability density functions (often a humped-back curve) or the cumulative distribution function (often an S-shaped curve) using conventional scaling systems for the vertical axis and the horizontal axis. The program also generates reliability growth curves using the Duane-AMSAA method and calculates the indices for demonstrating improvements in mean time to failure and other key reliability indicators. Pie charts and bar graph formats are available. The software will plot functions, fit curves, perform transforms on the data, and display the results in graphical format. User manual information is available on-line by <F1> key stroke.

Specific features of the SuperSMITH Visual program are:

      General and advanced scientific plotting
      Curve fitting (new data set added with 101 points)
      Crow/AMSAA reliability growth made easy
      Functions—data independent
      Transforms-global edit of data based upon functions

      Calculator functions for probability-binomial, chi-squared, gamma, Poisson
      Cumulative Distribution (CDF), Hazard (HDF), Probability Density (PDF) and Reliability (RDF) plotting from SuperSMITH Weibull file
      Aggregate Cumulative Hazard (ACH) plotting from SuperSMITH Weibull file
      Unlimited number of data using the frequency table format
      Expanded batch capability especially useful for network operation
      Pull-down menu
      Warranty data input
      Easier file selection
      Easier keyboard data entry
      Eay access to other software
