A method of troubleshooting a real world system having multiple components, and containing any combination of intermittent or non-intermittent faults, the method comprising:generating a model of the real world system, the system model including multiple model components;

associating with each model component of the system model, two probabilities, (1) a probability the real world component deviates from its design such that it may exhibit a malfunction, and (2) (for potentially intermittent components) a conditional probability the faulted component malfunctions when observed;

recalculating the conditional probabilities associated with possible fault causes, to guide a next stage of observation and/or

measurement;

undertaking a next stage of observation and/or measurement;

determining when enough data has been obtained; and

reaching a final result.

Title Diagnosing intermittent faults in telecommunication networks

Description

In model-based diagnosis one of the assumptions usually made is that components behave non-intermittently. Often this is an implicit assumption or it is made as a kind of afterthought because it makes the proposed algorithms simpler. In this paper we describe an approach, based on probability calculus, which can deal with intermittent behavior of components.
