Expert Opinion Fusion Framework Using Subjective Logic for Fault Diagnosis

A Mathematical Approach to Design Verification Strategies That Incorporate Corrective Activities as Dedicated Decisions

“…The CPTs of all nodes are synthetic and have been generated using probabilistic causal interaction models (i.e., generalized noisy-OR and noisy-AND models) [52]- [55], which take into account the physical meaning of the different nodes when estimating their mutual effects for reasonability of the data. This approach has been used in prior verification research [8], [56]. In this experiment, we assume that system revenue is driven by system parameter θ 6 .…”

Modeling correction activities in the context of verification strategies

“…Nodes represent the random variables, which we are interested in gaining knowledge about, and arrows between nodes represent the probabilistic dependencies between the nodes 39 . The basic BN has been extended to serve more sophisticated modeling needs, such as dynamic BN (which captures the change in beliefs as a time series model) 40,41 , object-oriented BN (which allows large-scale systems to be described in terms of inter-related objects) 42 , and subjective BN (which generalizes BNs to the theory of subjective logic) 43,44 .…”

“…Only two procedural differences are noted. First, while determining priors for models of recurring systems likely rely on historical data, models of newly developed systems need to resort to subject matter experts 75 or fusion techniques 44 . Second, while all kinds of CAs may be necessary for a newly developed system, redesign activities are typically unnecessary for recurring systems.…”
