To address the problem of long-cycle Combat Air Patrol （CAP） position maintenance in high-intensity confrontation， a time-space coordination method for air refueling management for CAP position maintenance is proposed. Firstly， based on the task requirements of long-cycle CAP position maintenance， a time-space coordination model for multiple refueling management sub-tasks including fighters rotation and tanker rotation are proposed with a comprehensive consideration of the mission effectiveness and efficiency of CAP. Secondly， a comprehensive mission objective model including four types of objectives of force requirements， airfield sortie frequency， sustained flight duration， and takeoff load configuration is established，and a program effectiveness evaluation model oriented to mission effectiveness are established. On this basis， the feasible solution of time-space cooperative refueling management is calculated by multi-objective optimization algorithm.Finally， the key elements affecting the effectiveness of time-space synergy in refueling management in typical mission scenarios are analyzed with a simulation. The experimental results show that the proposed air refueling management model can generate a reasonable and feasible time-space cooperative refueling management solution for a given CAP mission， and effectively support the long-cycle CAP position maintenance. Compared with the scenario without refueling support， with the time-space collaborative management approach proposed in the paper， the given force can meet the long-period combat patrol mission with more complex mission requirements， and the force requirement can be reduced by 37.5%， the airfield usage intensity can be reduced by 62.5%， the minimum takeoff fuel quantity of fighters can be reduced by 54.3%， and the overall mission effectiveness can be improved by 47.3%.
