How do you pronounce the
Swedish name Waloddi Weibull? If
you’re: 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 |

WinSMITH Weibull operates in
a Windows 95, Windows NT, Windows 2000, Windows XP, and Windows Vista
operating environment (having trouble with your WinSMITH software working in Price list for the software also provide for volume discounts. Version 5.0 is available as a CD in 32-bit format. 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 WinSMITH Weibull and WinSMITH Visual Training Manual is used for the 1.5 day WinSMITH Weibull and WinSMITH 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 the WSW-WSV Training Manual. This will help you get started with 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 WinSMITH 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.
For details about each WSW revision, see the bottom of this page when considering upgrades for Weibull analysis software. The following graph was made in WinSMITH 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.
Specific features of the WinSMITH 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
analysis of age-to-failure data to make upper and lower Gumbel distribution
probability plots
Performs normal (Gausian) analysis of age-to-failure data to make normal
probability plots
WinSMITH Weibull software output
is used in WinSMITH 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
1)
modified likelihood ratio test,
2)
confidence bound comparison at B-value, and
3)
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 added
to Weibull in test requirements
Binomial (bi) as well as Fisher Matrix
(fm) and Likelihood Ratio (lr)
confidence at any % for point-by-point data
Probit
confidence and Greenwood’s confidence at any % for 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
Available in 32-bit programs (long file
names, larger file size, and better compatibility with LAN printers)
Data output from WinSMITH Weibull can be imported into other software by Fulton Findings such as WinSMITH Visual with the click of a single icon button.

2) Analysis title
3) Analysis date
4) Analysis author
5) Type of occurrence mechanism (root cause
... such as cracking, leaking, etc.)

18)
WinSMITH(TM) Weibull software for making automatic Weibull library entries
contains a new icon (book symbol) under the setup portion of the software for
activating this feature. When the feature is activated, the software will
prompt you for additional information not normally stored in the analysis data
file (like type of occurrence mechanism, type of environment, etc.). Then 20
data fields (16 fields plus 4 comments) are generated using this additional information
plus information that the program already "knows" (like type of
distribution model, fit line slope, etc.) and then they are stored in a
selected text file as a one-line entry for later insert into the Weibull
library. Such a data base could be used
for background in selecting the appropriate Weibull beta for the more accurate Weibayes method as well as providing a
"lessons-learned" data base for the design department.
Special Note
For Some Version Of Windows 2000 service pack 0:
Three cases have been reported where
WinSMITH Weibull experienced failure to run after installation on early
versions of Windows 2000 (I never had a problem with my zero service pack)
which have not been updated with current service packs—all problem cases were
cured by downloading Microsoft, no-cost, upgrades from http://v4.windowsupdate.microsoft.com/en/default.asp. Please note you MUST install
the upgrades in sequence to avoid problems—don’t do a short cut as you can
incur fatal problems with your operating system. You can learn the operating version/service
pack installed on your computer, open Excel, click on Help, click on About, click on System Info… and your computer will gather
the Operating System and Version details.
My computer shows Microsoft Windows 2000, Version 5.0.2195 Service Pack 3, Build
2195.
