Aiming at the economic deficiency of the letter check maintenance mode,a novel collaborative optimization policy of tail assignment and maintenance scheduling was proposed by integrating individual maintenance require-ments and fleet-level operation and limited resource sharing.To couple the flight path and the maintenance scheme,an innovative modification to the connection network model was achieved.Assisted by the critical interactive role of maintenance opportunities covered in the flight path,the tail assignment and maintenance scheduling were overall considered in a consistent framework.A network-based collaborative optimization integer programming model was formulated with the comprehensive consideration of the operational constraints of flight coverage and continuity and the maintenance constraints of airworthiness requirements and resource capacity limitation.A problem decomposi-tion-based two-stage algorithm was presented based on the maintenance opportunity-oriented tail assignment optimi-zation and the reasonable maintenance task allocation procedure,which efficiently output the collaborative scheme.The computation results of a set of airline instances showed that the proposed method could effectively obtain a sig-nificantly cost-effective scheme,which provided assistance for the airline maintenance scheduling optimization.
