To support the creation of engine overhaul workscope during its life cycle
and reduce the overhaul cost in its life cycle
based on the engine maintenance management program provided by manufactures
by setting the overhaul interval which is less than the maximum overhaul interval
and taking account of the life of life limited parts and soft time of modules
an engine overhaul cost optimization model was presented in the paper for a modular engine
which took the overhaul interval as the variable and the least shop visit cost per flight hour as a target
the genetic algorithm was used to solve this optimization problem. Taking V2500 as an example
its shop visit workscope was optimized
it gave that 6 shop visits in 25 years have the lowest cost
and the repair levels of each module were also created for each shop visit. It can provide a reference method for airlines to make engine workcope for shop visit.
