Modeling and Troubleshooting with Interventions Applied to an Auxiliary Truck Braking System
2009 (English)In: Proceedings of the 2nd IFAC Workshop on Dependable Control of Discrete Systems (DCDS), 2009, 251-256Conference paper (Refereed)
Abstract [en]

We consider computer assisted troubleshooting of complex systems, where the objective is to identify the cause of a failure and repair the system at as low expected cost as possible. Three main challenges are: the need for disassembling the system during troubleshooting, the difficulty to verify that the system is fault free, and the dependencies in between components and observations. We present a method that can return a response anytime, which allows us to obtain the best result given the available time. The work is based on a case study of an auxiliary braking system of a modern truck. We highlight practical issues related to model building and troubleshooting in a real environment.
