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 largersized icons with associated dropdown 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 Weibull is a Windows
based probability plot software which is compliant with Section 508 of the Rehabilitation Act of 1973.


SuperSMITH
Weibull software by Fulton Findings produces probability plots
for distributions: 
How do you pronounce the
Swedish name Waloddi Weibull? If you’re: Norwegian WaLoddi VayBull
German VahLodi VyBull
French WahLodi WayBull
Polish VahLodi VyBull American WahLowD YBull 

SuperSMITH Weibull operates in a Windows 95, Windows NT, Windows 2000, Windows XP, Windows Vista, Windows 7 and Windows 10. 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 tablet, and may 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 handson 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 preversion 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 Weibull plot.
Nocost demonstration software can be downloaded for evaluation and teaching. Universities can use the demonstration software to analyze datasets saved from authentic SuperSMITH Weibull 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—remember not to save the DEMO file over the authentic version as it will destroy the authentic file integrity.
For details about each SuperSMITH Weibull revision, see the bottom of this page when considering upgrades for Weibull analysis software. The following graph was made in SuperSMITH Weibull and it is a Weibull plot using rank regression techniques with pump seal life data.
Agetofailure and strength data from field or laboratory tests are quickly plotted into straight lines to create order from the apparent random failure events.
How much data can you input? 12 columns of data with each column having up to 32,000 rows for both actual failures and censored data.
Normal, Lognormal, Gumbel, and Weibull probability plots are available along with probit analysis when data is acquired at periodic inspection intervals. Age/time corrections can be computed automatically to correct probability plot curvature when the age/time origin is not zero. Optimum replacement intervals are available when costs are supplied. The program calculates confidence intervals and performs risks analysis. Weibayes forecasts of age to failure are generated with only a few keystrokes.
Data suspensions for different failure modes and when components have not failed can be input individually or by histogram. Data sets can be analyzed to find the "best" probability distribution using the distribution analysis feature. Goodness of fit values are compared to critical values to show if the analysis is valid for the model chosen.
KaplanMeier data can be input through the inspection feature of the program
and displayed in all probability plot formats. User manual information is
available online by <F1> key stroke.
Specific features of the SuperSMITH Weibull program
are:
Performs Weibull analysis of agetofailure data to
make Weibull probability plots
Performs lognormal analysis of
agetofailure data to make lognormal probability plots
Performs Gumble
upper distribution analysis of data where each data point is the largest value
Performs Gumble
lower distribution analysis of data where each data point is the least value
Performs normal (Gausian) analysis of agetofailure data to make normal
probability plots
