Message:
I am evaluating PRISM software. Where can I get a standard that has all the equations, pi factors and base failure rates? For eg. if I use MIL-HDBK-217FN2, I can look up the equations, pi factors, base failure rates etc in the standard which is available free of charge. If I use Telcordia, I can buy the standard from them. What about PRISM? Can I buy it from RAC or is it available free of charge on some website? Will I get a copy if I buy the software from RAC?

The PRISM includes many interactions between differing factors and many of these factors are each based on equations and there are not tables of data showing extremes. That is why when the RAC developed and released PRISM we made it a computer program and not a handbook as the latter would have been difficult for a user to implement. The RAC PRISM includes a User manual that contains information on most equations and factors used in component and system predictions. To learn more about PRISM and to download a demo version of the software, go to: http://rac.alionscience.com/prism
