Abstract: Supports which UCAV system providing include that mission planning and control station presents clear and unambiguous interface and directions for operators，and variable authorization task management strategy of agents on-board allocates tasks and functions between operators and UCAV.Those must be based on human interaction with automation and divided into many levels of decision aiding such as“at call”，“advice”and“veto”.An experiment is developed to test quantitatively the efficiency of those levels and disadvantages induced by systems mistake.At last conclude that the efficiency of those levels is equal，and reliability beyond 35% can be employed through compared response time and accuracy of manual and other three operation ways with aiding.The conclusion can direct the design of decision aiding system in UCAV.

摘要： 无人作战飞机的辅助决策系统包括两部分：任务规划与控制站为操作者呈现清晰明确的任务界面和操作提示；机载智能体的变权限任务管理策略为操作者和无人机动态分配任务和功能，这些辅助都基于人与自动化的交互关系，分为召唤、建议和否决多个辅助决策等级。为了定量评测各级辅助决策方式的效用和辅助不可靠的负面影响，设计开发了等级实验。通过比较操作者手动和三种辅助操作方式的反应时间和正确率，得到了三种辅助决策等级的效用基本相等，辅助可靠性超过35%时就可以采用等实验结论，结论可以用来指导无人作战飞机辅助决策系统的设计。
