Resumen o descripción

Diagnosis and prediction m some

domains, like medical and industrial

diagnosis, require a representation that

combines uncertainty management and

temporal reasoning. Based on the fact

that in many cases there are few state

changes in the temporal range of

interest, we propose a novel representation

called Temporal Nodes Bayesian

Network (TNBN). In a TNBN each node

represents an event or state change of a

variable, and an arc corresponds to a

causal-temporal relation. The temporal

intervals can differ in number and size

for each temporal node, so this allows

multiple granularity. Our approach is

contrasted with a dynamic Bayesian

network for a simple medical example.

An empirical evaluation is presented for

a more complex problem, a subsystem of

a fossil power plant, in which this

approach is used for fault diagnosis and

event prediction with good results.
