Abstract
A diagnosis engine for diagnosing a device having a plurality of components receives test results of a set of tests on the device where at least one test has failed, and a model giving the coverage of the tests on the components of the device and information describing probabilistic dependencies between the tests. The diagnosis engine includes a specifier to specify a number N of components that may be simultaneously bad, N being an integer, and a computer to compute, within floating point computation errors, a likelihood that each of subsets of the components having size less than or equal to N are the bad components.
