posted on 31.10.2008, 11:40 authored by Darren R. Prescott, J.D. AndrewsThis paper offers an alternative method of modeling the
Time-Limited Dispatch (TLD) of aircraft. Existing methods
involve the use of fault tree analysis and Markov analysis with
various simplifying assumptions. Monte Carlo simulation
(MCS) is the suggested alternative, which overcomes the
problems associated with the other techniques, such as
dependencies between basic events (fault tree analysis) or
huge number of system states (Markov analysis). The results
obtained from the analysis of a simple example are compared
for the existing modeling approaches and MCS. MCS is seen
to have potential advantages, especially when modeling TLD
for large, full scale systems.
