Title:
METHOD AND DEVICE FOR CONTROLLING AN INDUSTRIAL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/131617
Kind Code:
A3
Abstract:
A tractable abduction procedure for a lightweight description logic EL is introduced extending recent research on automata- based axiom pinpointing by assuming information from a predefined abducible part of the domain model. The approach is motivated by the need for efficient diagnostic reasoning for large-scale industrial systems where observations are partially incomplete and often sparse. A weighted automaton can be constructed that commonly encodes a definite and abducible part of the domain model. Advantageously, the approach provides a compact representation of all possible hypotheses explaining an observation, and is in fact computable in PTIME. The invention can be used for controlling, adjusting or diagnosing all kind of technical systems, in particular in the area of industry and automation.
