Reliability-Centered Maintenance Optimization Tool

📖 User Manual
Educational Tool: Compare economic optimum maintenance intervals with manufacturer time limits (LIM). LIM = Maximum flight hours equipment can operate before mandatory maintenance. Adjust parameters to explore cost vs. compliance trade-offs!
Pre-defined Scenarios

Select a scenario to auto-fill parameters:

Critical Safety Component

High failure cost justifies frequent maintenance

Default Example

Typical hydraulic component in commercial aviation

Expensive Preventive Maintenance

High PM cost makes run-to-failure attractive

Infant Mortality Case

High early failure rate (new design)

Highly Reliable Component

Low failure rate allows extended intervals

Optimization Parameters
$
Cost to perform scheduled maintenance
$
Cost when component fails unexpectedly
flight hours
Average flight hours between failures (λ = 0.0000667 failures/hour)
Enable for non-constant failure rates (infant mortality: β<1, wear-out: β>1)
flight hours
Maximum flight hours before mandatory maintenance (manufacturer limit - cannot be exceeded)
Advanced Options (Optional)
