SuperSMITH Weibull
Probability 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 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:
            Weibull,
            lognormal,
            Gumbel (upper and lower), and
            normal (Gaussian)
probability-plots to analyze data used for making reliability improvements.  For revision details,

How do you pronounce the Swedish name Waloddi Weibull?  If you’re:
   Swedish-      Wa-Loddi Vay-Bull

   Norwegian-  Wa-Loddi Vay-Bull

   German-       Vah-Lodi Vy-Bull

   French-        Wah-Lodi Way-Bull

   Polish-         Vah-Lodi Vy-Bull

   American-    Wah-Low-D Y-Bull
No one says Wee-Bull!

 

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.

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 Weibull plot.

No-cost 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.

Age-to-failure 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.

Kaplan-Meier data can be input through the inspection feature of the program and displayed in all probability plot formats. User manual information is available on-line by <F1> key stroke.

Specific features of the SuperSMITH Weibull program are:
      Performs Weibull analysis of age-to-failure data to make Weibull probability plots
       Performs lognormal analysis of age-to-failure 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 age-to-failure data to make normal probability plots
       SuperSMITH Weibull software output is used in SuperSMITH Visual software
                 for PDF, CDF, and Hazard plots
       Complete interval maximum likelihood capability is easily accessible
       Expanded interval/probit analysis capability with Kaplan-Meir method and clipboard
                 probit data entry
       Exclusive set comparison techniques with
                 modified likelihood ratio test,
                 confidence bound comparison at B-value, and
                 likelihood contours
       Test planning with any number of allowed failures (up to test sample size) for life/reliability/
                 /confidence requirement testing or demonstration of improvement
       Normal and lognormal distributions are included in the test requirements
       Binomial, Fisher matrix, likelihood ratio and pivotal confidence bounds at any % for
                point-by-point data
       Probit confidence and Greenwood’s confidence are available for % with grouped data
       Calculator functions—binomial, chi-squared, gamma, Poisson
       Three parameter solution with either rank regression or maximum likelihood
       Next expected occurrence for risks plus risk analysis for grouped data
       Probabilistic – Strength/Load, Life/Usage, and tail comparisons for accelerated testing
       Parameter as function of engineering variable (PFEV) for accelerated testing data
       Warranty data analysis
       Improved zoom capability
       Unlimited number of failures and suspensions using the frequency table format
       Expanded batch capability especially useful for network operation
       Easy access to other software
       Language capability—US English, Francais, Deutsch, Espanol, Svenska, Portugues, Italiano
       Written as a 32-bit program (long file names, larger file size, and compatibility with LAN
               printers)
