Efficient Inference on Generalized Fault Diagrams
This work addresses failure analysis in systems with complex dependencies, but it appears incremental as it builds on existing influence diagrams.
The authors tackled the problem of analyzing failure scenarios with dependent events by defining a generalized fault diagram and developing a heuristic procedure for efficient processing, though no concrete performance numbers are provided.
The generalized fault diagram, a data structure for failure analysis based on the influence diagram, is defined. Unlike the fault tree, this structure allows for dependence among the basic events and replicated logical elements. A heuristic procedure is developed for efficient processing of these structures.
