Fact Sheet for Technical Note 1 is now available (29.10.2018). 

The Technical Note TN-1 provides the findings and major results of the Task 1 prepared in the frame of the study “New Reliability Prediction Methodology Aimed at Space Applications”, under a programme of and funded by the European Space Agency. The objective of TN-1 is to provide an assessment of the current state of reliability predictions in space applications and their inherent limitations and shortcomings.

Fact Sheet for Technical Note 2 is now available (24.03.2019). 

The Technical Note TN-2 provides the findings and major results of the Task 2 prepared in the frame of the study “New Reliability Prediction Methodology Aimed at Space Applications”, under a programme of and funded by the European Space Agency. The objective of TN-2 is to develop an approach for the improvement of the in-use methodologies. It is based on the assessment of limitations and shortcomings of the current reliability prediction ap-proaches presented in TN-1.

Fact Sheet for Technical Note 3 and 4 is now available (24.08.2020). 

The Technical Notes TN‐3 and TN‐4 provide the findings and major results of the Task 3 and 4 prepared in the frame of the study “New Reliability Prediction Methodology Aimed at Space Applications”, under a programme of and funded by the European Space Agency.

TN‐3 provides a complete set of ground rules and requirements as an input for the development of the New Reliability Prediction Methodology (TN‐5). Ground rules are general rules that have to be kept in mind during the development but cannot be linked to a specific target to check its applicability. The requirements are rooted from the ground rules and are formulated such that they can be verified after the finalization of TN‐5.

The purpose of TN‐4 is to already define the approach for the verification and proof of concept of the New Reliability Prediction Methodology before starting its actual development. The proof of concept foreseen for TN‐6 will comprise both a qualitative evaluation and a quantitative benchmarking of the new methodology.

Fact Sheet for Technical Note 5 is now available (24.08.2020). 

The objective of TN-5 is the development of a new reliability prediction methodology for space applications. It is based on the approach defined in TN-2 (see TN-2 Fact Sheet for a short summary) and the requirement specificiations and ground rules defined in TN-3 (see also TN-3/4 Fact Sheet).
It serves as a basis for the proof of concept in TN-6 and – after performing an update in TN-7 – will be used as the major input for the final reliability prediction handbook (TN-8).

Fact Sheet for Technical Note 6 and 7 is now available (14.09.2020).

The proof of concept presented in TN‐6 includes a quantitative assessment and benchmarking of

reliability prediction results as well as a qualitative assessment of the methodology based on the

criteria defined in TN‐4.
TN-7 is an update of TN-5 based on the lessons learned from TN-06. 
This is the last Fact-Sheet of the project.

TN-8 is the final handbook comprising of the work in TN-1 to TN-7 providing e.g. a

• Framework for reliability prediction
• Basis for modelling time dependend failure rates
• Basis for  EEE  parts reliability,
• Basis for  Mechanical parts reliabilit
• Basis for miscellaneous units and a
• Basis for System analysis.

• Tender presentation
• Reliability of mechanical systems and parts
• Effective Reliability Prediction for Space Applications (ESA White Paper)
