June 10-12, 2013, Winterthur, Switzerland, Reliability and Safety Workshop

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

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

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
