Section: New Results

Piecewise Deterministic Markov Processes based approach applied to an offshore oil production system

Participants : Huilong Zhang, Fares Innal, François Dufour, Yves Dutuit.

This work is keeping with the topic of two papers which treated dynamic reliability problems and were presented in previous conferences. Its aim is to confirm the potentialities of a method which combines the high modeling ability of the piecewise deterministic processes and the great computing power inherent to the Monte Carlo simulation. This method is now applied to a simplified but realistic offshore oil production system which is a hybrid system combining continuous-time and discrete-time dynamics. The results thus obtained have been compared with those given by an ad hoc Petri net model for comparison and validation purposes. This work has been published in an international journal; see [29] .
