对装备系统工程的复杂性进行了初步的认识 .对于该类系统工程中的复杂现象运用“人 -机 -环境系统”的基本思路 ,通过对航空装备系统工程问题研究的典型具体实例——军用飞机主要维修性参数 DMMH/ FH指标的评估 ,以及“勺形曲形”的发现过程 ,阐述了装备系统复杂性研究的基本方法 .

In this paper, by using the idea of 'human machine environment system engineering', the complex appearance in system engineering is studied and by a typical example of research on aviation equipment system engineering complexity problem——estimate military aircraft main maintainability parameter DMMH/FH (direct maintain man hour/ fly hour) and then discovering the spoon curve, a fundamental method for the complexity of equipment system engineering is investigated.
