Active Diagnosis for Probabilistic Systems [chapter]

Nathalie Bertrand, Éric Fabre, Stefan Haar, Serge Haddad, Loïc Hélouët
2014 Lecture Notes in Computer Science  
This system is then diagnosable if the fault can always be detected, and the active diagnosis problem consists in controlling the system in order to ensure its diagnosability.  ...  In this setting, the active diagnosis problem consists in deciding whether there exists some observationbased strategy that makes the system diagnosable with probability one.  ...  Conclusion We studied the active diagnosis and safe active diagnosis problems for probabilistic discrete event systems, within a unifying POMDP framework.  ...
