Final Remarks and Outlook

In order to illustrate this issue, the paper considers an industrial controlled system on which a comparison study is performed. First the system failure is represented by a model that complies with the BDMP formalism. Second, the minimal cut sequences are extracted from this model. Section 2 describes the case study and gives the definition of the BDMP formalism. Section 3 applies the MBSA stated above while considering only the process failures. Then a control architecture is described, and added to the model in section 4. For integrating these new failures in the model, three models are proposed and discussed. In the same section, the set of minimal cut sequences is updated, and compared with the previous one. This comparison shows that the control failures have a significant influence on the qualitative analysis of the system. Finally, the last section draws up concluding remarks and outlooks.
