June 10-12, 2013, Winterthur, Switzerland, Reliability and Safety Workshop
Day 1
Morning Session
MTBF prediction
- System structure (sub systems, assemblies, components)
- Using ready component libraries
- Inputting new components into library
- Defining electrical stress
- Defining operational and non-operational conditions
13:00-14:00
Lunch
Afternoon Session
- Running reliability prediction and allocation
- Generating reliability prediction reports
- Importing/exporting system structure and reliability data
- How users can control prediction results
- Independent exercise with an MTBF example
Day 2
Morning Session
FMECA
- Importing system structure and component failure rates from MTBF project
- Generating / inputting component failure modes with failure ratios and effects
- Sequential building of next higher effects chains up to system end effects. Local and global approaches. Some effects and causes of a failure mode. Effect probabilities
- FMECA principles:
- Possible effects of each failure are considered under the condition that no other failures occur
- Only one failure mode can occur at a time
- Propagating failure mode rates from components, through assemblies, and up to the system end effect
13:00-14:00
Lunch
Afternoon Session
- Severity, Criticality and Probability of a failure mode and an item
- Controlling FMECA results: Mission phases, phase time, ranking failure modes and items
- Exporting FMECA structure and data
- Generating FMECA reports
- Independent exercise with an FMECA example
Day 3
Morning Session
RBD and FTA
- Importing system RBD structure and data from MTBF project or FTA
- Defining redundancy and repair type in RBD
- Failure time distributions of RBD components and assemblies
- Running RBD calculation. MTTCF and MTBCF. Effect of repair type on Reliability and Availability
- Generating RBD report and hierarchic Reliability Block Diagram
- Exporting RBD structure and data
- Independent exercise with an RBD example
13:00-14:00
Lunch
Afternoon Session
FTA
- Importing system FTA structure and data from MTBF project, FMECA or RBD
- Inputting a failure cause as an independent or repeated failure event. Sense of repeated events
- Used event icons and their meaning. Event probability meaning with and without recovery
- Compact and traditional form of Fault Tree. Allocating traditional Fault tree on pages
- Exporting FTA structure and data. Generating FTA report
- Independent exercise with an FTA example
