20. Pylos (Greece), 16-18 April 2007 KM3NeT : Colaboration meeting20 WP7: RA Objectives & Road Map for KM3NeT Road Map Risk Analysis involves three major stages: Collect project/processes data; Assessment of the undesired consequences of a potential set of actions; Assessment of the probability that these consequences may obtain. Objectives 1)Define the mission of the neutrino telescope in quantifiable terms; 2)Assess specific scenarios (sequences of events) that can lead to the inability of the system to perform its mission; 3)Assess the probability of each and every scenario.

21. Pylos (Greece), 16-18 April 2007 KM3NeT : Colaboration meeting21 WP7: Risk Analysis Actual Activities FMECA ANALYSIS Qualitative Example (related to PCC Rome Meeting Request) Analyzed Component : Optical ModuleOptical Module Hypothesis: 1.OM into its environmental conditions (working life); 2.Components cant’be repair (MTBF=MTTF=1/λ)(MTBF=MTTF=1/λ) 3.Criticality Analysis is only qualitative and based on MIL-STD 1629 A normative ; 4.Objects Information are based on the available licterature (there are not yet available risk data). Goals:  Give remarks about possible test benchs development to simulate the Failure Causes put in evidence;  Focus on Risk parameters needed.

22. Pylos (Greece), 16-18 April 2007 KM3NeT : Colaboration meeting22 WP7: Risk Analysis Actual Activities FMECA ANALYSIS Steps  Explode the Objects under analysis in all its parts (through a filled Questionnaires)(through a filled Questionnaires)  Build up FMECA TABLE by using modified MIL-STD 1629 A worksheet worksheet  Put in evidence the relevant functions by logical flow diagramflow diagram  Brainstorming on potential failure modes, causes and effects  Allocate severity level and probability of occurrence using MIL- STD-1629 A reference tablesreference tables  Build Up “Criticality Matrix”“Criticality Matrix”  Give final remarks

23. Pylos (Greece), 16-18 April 2007 KM3NeT : Colaboration meeting23 WP7: General RA Conclusion 1.Although Qualitative, Criticality Matrix focuses on : Possible Criticality, using color ranking from Red (unacceptable condition) to Green (acceptable without revision) Objects ordered by criticalities 2.Although Qualitative, Criticality Matrix gives a priority to the objects tests (related to the failure causes) based on the above ranking Example of procedure after FMECA results: Step 1) rank Criticality level by unacceptable to acceptable Step 2) Calculate experimental MTBF from the worst to the better condition Step 3) Verify availability and find solution to improve, if is necessary

29. Pylos (Greece), 16-18 April 2007 KM3NeT : Colaboration meeting29 WP 7 results 1 of 2 The work performed outlines that for a correct application of the QA and RA, it is needed to develop in the design study:  Functional analysis  Definition of the requirementes  Definition of the technical specifications It means interaction with the WPs

30. Pylos (Greece), 16-18 April 2007 KM3NeT : Colaboration meeting30 WP 7 results 1 of 2 The QA/RA needs to define the reliability level to be reach. It is translated in:  Tests to be performed  Relation with the suppliers, which -Tests they should perform -Certificate they should release -Level of non conformity we consider acceptable  Definition of the preproduction and production specifications
