Abstract

Method and apparatus for generating and outputting dynamic variance reports for vehicle operations. The dynamic variance reports enable a vehicle operations scheduler to understand trends, patterns, or the like in variances between planned vehicle operations and actual vehicle operations. The understanding of the variances provided by the dynamic variance reports enable the scheduler to apply buffers to vehicle operations plans so that planned vehicle operations more closely match actual vehicle operations and crew assignments are less likely to be disrupted.
