Abstract:

Systems and methods for optimizing a plurality of competing portfolios of logistical alternatives are disclosed. In one embodiment, where the competing portfolios of logistical alternatives are competing portfolios of flight paths, a method () for optimizing a plurality of competing portfolios of logistical alternatives includes receiving () competing flight path portfolios from one or more flight operation centers. Dominance criteria are applied () to select a subset of the portfolios from the plurality of competing portfolios for further consideration. Multi-objective genetic optimization is applied () to the subset of portfolios to identify an optimal portfolio among the plurality of competing portfolios of logistical alternatives. Where the method () is undertaken by executing computer program code on at least one computer processor, information identifying the logistical alternatives included in the optimal portfolio may be output () on an output device in communication with the computer processor.
