Bayesian network model for K-variant systems

Bayesian network tool can be used to estimate the survivability of K-variants systems. Also, it helps designers of K-variant systems to make decisions on the design elements of K-variant systems. You may try our online tool, which utilizes our Bayesian network model.

You may also download our Bayesian netowork model in xbn format (can open in MSBNx, Microsoft free tool )
