Task allocation method is an important part of the task control process and plays a key role in team cooperation C2. This paper mainly analyzed the notable characteristics of the manned/unmanned aerial team based on the multi-UAV cooperative task allocation. This article focuses on the impact of the pilot performance on each UAV operational effectiveness, and established a pilot performance evaluation model which on account of pilot flight time and workload, and also has improved the traditional UAV mathematical model of combat effectiveness function, and proposed UAV effectiveness evaluation model which influenced by pilot performance when manned aerial vehicle has participated. Simulation about the cooperative task assignment of manned/unmanned aerial vehicle team results indicates: pilot performance have a significant impact on UCAV mission effectiveness and team task assignment, also indicates the pilot performance should not be ignored in task assignment process of manned/unmanned aerial vehicle team.
