Simulation of Engine Build
SEB was first applied to determine the
unit cost for the decisions that were
made without using ELO to optimize
the engine lifetime.
Minimum Build Optimizer
MBO was then used to identify the
life-limited parts replacement that would
result in lowering the unit cost. This is
done in two steps:
(1) Identify optimum minimum build that
results in the least unit cost.
(2) Apply SEB after replacement decisions
are made based on the least unit cost
minimum build in Step (1).
Benefit:
Applying ELO resulted in reducing the unit cost by $87.18 per flying hour ($144.73 per cycle).
