Sûreté de fonctionnementSafety requires mastery of the risks.
In order to be able to master the risks due to the characteristics of the system it is necessary to manage RAMS.
In France the quantitative proof of functional safety („Sûreté de fonctionnement") is subject to detailed requirements and to a procedure determined by the authorities. Since we are particularly specialized and we can offer a comprehensive know-how in this field, AEbt has created a separate department for the „Sûreté de fonctionnement" technology.
To comply with the high requirements to the RAMS management for the proof of safety during a system's whole life-time cycle, the methods of quantitative fault-tree analysis (FTA) and the methods of type of error status, type of error impact and criticality analyses (FMECA) are highly accepted.
By applying deliberately the methods and tools of verification management, we implement for you the following analyses:
- risk analyses (PHA);
- reliability analyses;
- availability analyses;
- maintainability analyses; and
- safety analyses
As a result of these analyses we provide you with the following:
- proof that safety, availability and maintainability requirements are met;
- identifi cation of common cause failures (CCF) and critical active chains;
- identifi cation of the potential breakdown of the safety responsibility in individual sub-systems and component parts;
- allocation of safety requirement levels (SIL) to sub-systems and component parts;
- specifi cation of the inspection requirements (inspection object, time interval between inspections); and
- development of technical improvement options.
