This affordable validation and reliability testing system pays for itself the first time you use it!

For company who is committed to gaining share in today's competitive global markets, one must be able to identify product parameters critical to quality, reliability, and profitability ratio. If you are the one who is responsible for planning, assessing, and monitoring product development programs, then the DRI CARS software system developed by Detroit Research Institute will be of benefit to you. The CARS Software was based on the life-long work of the late Leonard G. Johnson, originator of Weibull Analysis, and leading contributor to the most dynamic research in statistical reliability and life testing.

The CARS stands for Computer Aided Reliability System, is a comprehensive software system that emphasizes the latest developments of statistical methods for solving field failures, product reliability, and durability problems. CARS software has been tested and proven; and has been updated and used as a training tool in our training courses the last four decades.

The CARS is not a SPC or DOE software. It is a special tool that helps you design and analyze life tests with confidence to ensure the product is reliable enough in meeting your profitability and reliability goals. The CARS contains a variety of problem-solving programs that can help you get the job done quickly and economically.

The programs we offered do not require graphics. They are text based statistical analysis programs. Text based programs are faster, more efficient and more reliable than graphics programs. We have offered these programs on time-shared computers since 1971 with GE and Comshare and later on PC platform. These programs can be used on IBM Compatible PC using either DOS, Windows 3.1 or Windows95/98/ME/XP/Vista/7/8/10 (32-bit) Operating Systems. They even can be run on Apple with the help of a program called DOSBOX , it can be downloaded from the internet. Our programs truly are very convenient and portable. You don't have to install them on your hard drive in order to use them. You can run them from any removable disks. No special hardware needed. Use any USB flash drive or portable hard drive . No additional software required. Just download it and run. It is that simple. It's ideal and beneficial to have a personal copy of these programs. These portable programs or (apps) are self-contained in a single directory with sub-directories and files within. They don't leave files or folders behind on the computer.

Download the program "WEIBULL" on all Windows versions except Windows 8 and Window 10. (it can be run on Windows 8 and Windows 10 - 64 bit OS with the help of DOSBOX) to see how easy it is to use our software. This program is one of our stand-along CARS software in our library. You may use this free Weibull program to solve the following sample problems or your own set of data. It is the most popular tutorial type of program for solving life testing and field failure problems. If you are interested in more effective and accurate solutions to research and development programs then our complete CARS software will be a great help to you.
