In x5.6.4, we saw how the use of a sensor status node can be used to model both intermittent and persistent faults in the sensor. In the text this node had only two states, working and defective, which does not represent the different kinds of faults that may occur, in terms of false negatives, false positives, and so on. Redesign the sensor status modeling to handle this level of detail.

New Applications The BN, DBN and decision networks surveyed in this chapter have been developed over a period of months or years. It is obviously not feasible to set problems of a similar scope. The following problems are intended to take 6 to 8 hours and require domain knowledge to be obtained either from a domain expert or other sources.
