Call for papersDiagnosis is the reasoning process that aims at determining whether certain properties (such as the occurrence of a failure, of an unexpected measurement, or of a deviation from prescribed behavior) hold at a given time inside a system (fault diagnosis) and/or in its environment (situation diagnosis) and identifying their causes. Diagnosis reasoning is thus crucial for many reasons: safety/maintainability in supervised systems, robustness/decision autonomy of smart agents in their partially observed environment, reconfiguration of business strategies after a failure... Despite the huge spectrum of applications, Model-Based Diagnosis (MBD) problems are generic as any diagnosis algorithm relies on a class of models, or a modeling framework, that represents a larger class of systems. In the last decades, many diagnostic modeling frameworks have been proposed that are now well established. Nowadays, the community is more and more interested in understanding the power and the limits of such frameworks/techniques. Such studies allow to determine in advance how the diagnosis algorithm will behave. This is crucial especially if Diagnosis is the input of other automated reasoning tools (like planning, scheduling,...). The accuracy and performance of MBD algorithms depend to a large extent on some properties of the underlying model (correctness, fidelity, accuracy, diagnosability, predictability...). For example, the size of the model (measured as the number of variables and constraints) affects all major diagnostic metrics such as diagnostic accuracy, computational performance, etc. Tools for model analysis are necessary to assist both in the modeling and in the computation phases of MBD. Model analysis can be used for creating worst-case scenario benchmarks, asserting model correctness, and facilitating automatic or semi-automatic modeling. As such, model-based analysis can be done with the help of a variety of AI and optimization tools such as SAT and Max-SAT methods, search algorithms, optimal sensor placement algorithms, and others. The purpose of this workshop is to gather researchers from several related Model-Based Reasoning fields such as Model-Based Diagnosis, knowledge-compilation, satisfiability, planning and constraint satisfaction and optimization in order to fill the gaps and exchange ideas about which reasoning techniques are needed for the analysis of the various models used in MBD and the implication of these analyses to the performance of MBD algorithms. Possible topics include but are not limited to: * Relevant properties of model for diagnosis: + structural/behavioural properties, + detectability, diagnosability, max-fault min-cardinality, fault distinguishability, finite tractability, adaptability * Automated Model relaxation/abstractions techniques * Model/Algorithm interfacing * Model partitioning/decomposition for decentralized reasoning * Performance metrics, Diagnosis accuracy * Parametric computational complexity of MBD algorithms, anytime algorithms * Meta-modeling, Meta-diagnosis * Benchmarking of MBD algorithms, worst case scenarii synthesis |
