The supporting situation of carrier-based aircrafts is always changing,which will lead the time of processing supporting operation is not determinate.Thus,a rescheduling model is presented based on interval number,and four kinds of interval ranking rules are proposed. An improved differential evolution algorithm was proposed to resolve the model:Firstly,the codes are initialized with the shortest time and load balancing strategy as well as method of randomly generated while the priority contained therein;Secondly,the decoding is by the way of activity scheduling. Finally,the simulation results show the effectiveness of the model and algorithm.%航空母舰舰载机保障环境多变,导致航保资源的保障时间不确定,采用区间数的方法表示保障时间,建立了基于保障时间为区间数的调度模型.根据问题的特点,定义了4种区间数排序规则,并且在模型求解时,直接采用区间数计算.针对调度模型,提出了一种改进的差分进化算法,采用短用时和负载均衡策略以及随机生成的方法初始化编码,解码采取活动调度,改进变异规则,最后通过实验验证了模型和算法的正确性及有效性.
