Diagnosing Dependent Failures – an Extension of Consistency-based Diagnosis
نویسندگان
چکیده
Most applications of model-based diagnosis rely on the assumption that components fail independently. However, dependent failures are quite common in some domains. In such domains, the failure of one component may cause the failure of other components. Hence, multiple faults are much more likely, and the minimal diagnoses may not contain all components which have failed. In this work we propose the concept of diagnosis environments (DEs). DEs distinguish between independent and dependent failures, and they may consider components as failed which are not part of the minimal diagnoses. We provide a formalization of our approach and present an algorithm which computes all minimal DEs.

Leveraging the Short-Term Memory of Hardware to Diagnose Production-Run Software Failures
Failures caused by software bugs are widespread in production runs, causing severe losses for end users. Unfortunately, diagnosing production-run failures is challenging. Existing work cannot satisfy privacy, run-time overhead, diagnosis capability, and diagnosis latency requirements all at once. This paper designs a low overhead, low latency, privacy preserving production-run failure diagnosis...
متن کاملDiagnosing Coordination Faults in Multi-Agent Systems
With increasing deployment of multiple agents in complex, dynamic settings, there is an increasing need to respond to failures that occur in the agents coordination. In particular, there is need to detect and diagnose coordination failures—failures to maintain relationships between agents. We refer to this type of diagnosis as social diagnosis. Previous approaches to diagnosis in multi-agent se...
متن کاملAnalysis and Diagnosis of Partial Discharge of Power Capacitors Using Extension Neural Network Algorithm and Synchronous Detection Based Chaos Theory
Power capacitors are important equipment of the power systems that are being operated in high voltage levels at high temperatures for long periods. As time goes on, their insulation fracture rate increases, and partial discharge is the most important cause of their fracture. Therefore, fast and accurate methods have great importance to accurately diagnosis the partial discharge. Conventional me...
متن کاملTowards Model-Based Diagnosis of Coordination Failures
With increasing deployment of multi-agent and distributed systems, there is an increasing need for failure diagnosis systems. While successfully tackling key challenges in multi-agent settings, modelbased diagnosis has left open the diagnosis of coordination failures, where failures often lie in the boundaries between agents, and thus the inputs to the model—with which the diagnoser simulates t...
متن کاملMonitoring and diagnosing a two-stage production process with attribute characteristics
Multistage process monitoring has recently attracted notable attention in that the statistical relationships between quality variables are taken into account. Here, we dealt with the problem of monitoring and diagnosing a two-stage production process with attribute characteristics in which the outgoing quality variable is impacted by the incoming quality variable from the first process stage....
