  • Process and system for multi-objective global optimization of maintenance schedules
    Patent number: 8396571
    Abstract: A process for optimizing maintenance work schedules for at least one engine includes the steps of retrieving at least one set of data for an engine from a computer readable storage medium; selecting at least one scheduling parameter for the engine; selecting a set of maintenance rules for the engine; selecting at least one maintenance work decision; selecting at least one objective for the engine; optimizing the at least one objective to generate at least one optimal maintenance work decision; and generating at least one optimal maintenance work schedule for the engine.

  • Method and Means for Optimizing Maintenance Work Schedules
    Publication number: 20080162235
    Abstract: The optimization algorithm described herein combines stochastic programming and intelligent enumeration schemes that exploit the problem structure to avoid evaluating solutions that on their face are known to be non-optimal. The optimization algorithm finds the module workscope decisions and LLP replacement decisions that minimize expected future maintenance cost per engine flight cycle. The optimization algorithm considers the enormous number of possible solutions, and determines the best one.
