<P>PROBLEM TO BE SOLVED: To provide an obstacle factor estimation system for estimating the fundamental factor of an obstacle without further defining by manpower complicated dependency. <P>SOLUTION: An initial model generation means 40 generates an initial obstacle generation model by modeling the correspondence relation of an event and the occurrence factor and inter-occurrence factor transition by a finite automaton based on basic model definition 20. A Baum-Welch calculation means 50 learns which probability has resulted in the transition of the status of the finite automaton corresponding to the factor, based on the initial model occurrence model and an event column 100 for learning. A Viterbi calculation means 60 searches the status transition column in which the possibility of the observation of an event column 110 for obstacle factor discovery is judged to be the highest by an obstacle occurrence model after learning. A filtering module estimates the fundamental factor of the obstacle which has occurred in a monitor object device from the status transition column. <P>COPYRIGHT: (C)2008,JPO&INPIT |
