The invention provides a c and apparatus. The flight conflict resolution method comprises: establishing a flight conflict resolution model, wherein the flight conflict resolution model includes a flight delay situation and a flight conflict situation for all planes to be resolved; according to the flight delay situation and the flight conflict situation, determining a first objective function and a second objective function; utilizing a multi-object optimization algorithm to decompose the first objective function and the second objective function into a plurality of first sub objective functions and second sub objective functions; utilizing a crossover operator and a mutation operator to perform a Nth optimization generation of calculation for the plurality of first sub objective functions and the plurality of second sub objective functions to obtain a Nth generation of solution set; outputting the Nth generation of solution set if determining that the Nth generation achieves a preset cyclic algebra; and according to the Nth generation of solution set, performing flight conflict resolution for the planes to be resolved. The flight conflict resolution is high in operation efficiency and can perform conflict resolution to achieve lower average delay, and utilizes a multi-object optimization mechanism so as to meet the demand of a practical problem and obtain a scheme with higher feasibility.
