Bayesian networks versus other probabilistic models for the multiple diagnosis of large devices

Multiple diagnosis methods using Bayesian networks are rooted in numerous research projects about model- based diagnosis. Some of this research exploits probabilities to make a diagnosis. Many Bayesian network applications are used for medical diagnosis or for the diagnosis of technical problems in small or moderately large devices. This paper explains in detail the advantages of using Bayesian networks as graphic probabilistic models for diagnosing complex devices, and then compares such models with other probabilistic models that may or may not use Bayesian networks.
