# Constant-hazard mission reliability
# Scope: Exponential constant hazard mission survival; no wear-out.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

hazard = 0.00001 h^-1
duration = 1000 h

reliability := exp(-hazard*duration)

check mission reliability target: reliability >= 0.98

scenario alternative: hazard = 8e-06 h^-1
