We are quite capable of providing various statistical analyses for you. Alternatively, we can provide our proprietary MS Windows based, software, Weibull-Ease, for integration of market research and field data with laboratory tests, warranty failure cost estimates, and future reliability. Weibull-Ease was developed to satisfy the need for an accurate, easy to use, system to calculate reliability for medium to high volume production, before, during, and after production. Please note that, quite recently, we have changed the name Weibull Easy to Weibull-Ease as the title for this software package. The reason for the name is to emphasize its use of the Weibull distribution and its flexibility.
Those of you who use competitive programs would do well to download the demo and compare. We are quite confident that many of you who make a serious comparison will switch to Weibull-Ease as your standard department software. Please note, when making accuracy comparisons, that our regressions are all based upon rank regression on X (i.e. RRX).
If you're looking for meaningful results for anything from heart valves to battle tanks, and in a form that is understandable to non-technical management as well as technical professionals, we believe you've come to the right place.
In addition to the standard statistical analyses routines of the more well known software, Weibull-Ease uses a unique, simple, and understandable routine for comparing engineering's lab or field test data with marketing's field use data. Furthermore, we are willing and able to customize this or similar packages if you have unique requirements. Please call, write, or e-mail if you need to discuss customization.
NEW ROUTINES
1.) Multiple Mode Analysis Most recently, we have developed and added a very clean, easy, system for analyzing multiple failure modes based upon each mode's Weibull distribution parameters. The individual modes' are combined to allow creation of a single Weibull equation to represent the entire system, which can then treated as if it were a single mode. We believe this copyrighted routine is the most simple, easy to understand, procedure on the market today. This routine can also serve as input for the Market Use Analysis comparison routine. All failure modes for a given system or machine can be saved together and recalled as a single set. This application can be of use to analyze fleets of vehicles or equipment throughout an organization's, or even a country's, structure. Future production's field reliability estimates is one obvious application. Analysis of rental car fleets is another. Large scale medical product studies is another. Military vehicle or equipment reliability inputs into computerized competition models is yet another. The built-in sample data routine shows you how this works.
2.) Market Use or Customer Demand Analysis This data is typically provided by market research groups. This routine is to convert this market research use data in the form of quartiles by annual use, or as a normal distribution with standard deviation, into a form that can be compared to the product's capability. Here again, the analyses are based upon the Weibull relationships.
3.) Combined Distributions This routine compares the above multiple-mode Weibull capability analysis of a particular system, machine, or product (test data usually provided by engineers), and matches it against the Demand Analysis' Weibull estimate (typically provided by marketing groups) of the expected annual use of the same population of identical systems or products.
4.) Bearing Analysis Conversion of standard bearing load/life figures into Weibull reliability parameters. These can then be inserted directly into the Multiple Mode Analysis routine or used as is. Built-in sample data routine shows you how this works. We have also added a printout and PDF conversion for this section.
5.) PDF Files As of the February 20, 2008 upgrade, Weibull-Ease now includes a PDF alternative with all the print routines. This improvement, along with others, has come about due to requests from multiple users of the program.
6.) Zero Failure Test Planning As of the April 8, 2008 upgrade, Weibull-Ease now has the most practical, easy-to-use, and understand, Zero Failure calculation routine available anywhere. If you download the demo and try it out, we are quite certain you will agree.
For the past few weeks, we have been seriously re-working of all our routines. In addition, we hope you will all stay tuned for further adventures. With these latest improvements, Weibull-Ease is now easier to understand and learn, plus printouts neater and cleaner. Now, with the added the PDF output, we believe we are matching or exceeding the competitions' best, most useful, routines items for item. Our routines are those necessary to accomplishing the end of assisting you to put out a reliable product - - not simply a means of generating paper. These routines and printouts were created by, and are the result of solid, professional level input from practicing design, test, and reliability engineers from all over the country. While the numbers have always been accurate, we are always looking to significantly improve the presentations and reports, plus the ease of use of all the routines. Consequently, if you do download and see where we can improve, please let us know. There is a strong possibility we will incorporate your suggestion within the next one or two sets of changes – especially if you are a customer. Keep in mind, upgrades are at no charge for 18 months.
DOWNLOADS
To download (WEIBULL-EASE DEMO) click here. The demo is a complete program except that it has a 30 day time limit for its operation. If you need a little more time, please let us know and we'll figure out some way to accommodate you. If you have an earlier build version of Weibull-Ease with the same name or number, you should not have to uninstall. It should be automatic. After 30 days, the key code is necessary to make the program permanent. While trying it out, you may have questions. If so, or if you simply need clarification on some part of the program, please give us a call at (763) 521-0217 and we will gladly walk you through it.
Purchase and insertion of the key code eliminates the above demo's 30 day time limit. Purchase also includes the Weibull-Ease Manual, plus telephone support and updates for eighteen months. The present price for Weibull-Ease is $398 USD for a single seat. The unit price when purchasing multiple seats is less. To purchase by credit card click here. (WEIBULL PURCHASE). If you prefer, we can also work through your company's purchase order. To arrange this, e-mail jmb@applicationsresearch.com or call us at (763) 521-0217 or fax your P.O. to (763) 521-0269. An excellent reference for this program is the manual Practical Weibull Analysis, Fourth Edition, by James A. McLinn. This can be ordered through ASQ.
If you have any problem with the download, please e-mail us call us at (763) 521-0217. In most cases we will correct the problem almost immediately.
This revision is as of 8/11/08. If you've downloaded before then, you aren't quite current, so feel free to repeat the process as often as you wish. If you've downloaded much longer than a couple weeks back from the date shown, the improvements in function and related printouts may be dramatic. This is so much so, that even the graphics on this website have yet to catch up with the most recent features.
Weibull-Ease includes full three parameter analysis, confidence plots, suspended test compensation and automatic sort, plus grouped data insertion. Unique system of comparing market or field use data with test data to generate accurate prediction of field failure and warranty costs. It also includes routine to print scaled, labeled, Weibull paper. Also, we are not aware of any other software that prints out discrete reliability/failure values for the selected confidence limits. These are, at times, the most important figures sought by decision makers to facilitate their processes.
The typical worksheet for the Weibull distribution is as shown below. Note we use rank regression on X as this is preferred by virtually all authorities on life testing statistics. There are other ways to generate the numbers, but rank regression emulates the way the equipment design process works - - i.e. best fit for the best available information. Wars have been won and lost on proper (and improper) application of this principle to equipment design.
