Abstract: In view of the characteristic of the production organization pattern in domestic airline and the necessity and the feasibility of implementing the integrated airline fleet assignment,a new concept of aircraft-"flight pairing" assignment cost is defined as a technology economic index for evaluating the quality of fleet dispatching scheduling,and the theory framework of implementing integrates airline fleet assignment is found. The research indicates that the integrated fleet assignment formation is the tendency of airline operating management pattern,which is helpful to enhance airline fleet operating efficiency. Therefore it is not only necessary but also feasible.

Key words: integrated airline dispatching, flight pairing, evaluating function, mathematical model
