传统的航空电子系统的需求捕获方法忽视机组与机器设备协助的工作情况,而导致捕获的需求与人机接口需求脱节。定义机组和机器设备组成的系统为广义驾驶舱系统。通过捕获该系统的需求,获得机组功能、航空电子系统功能、其他相关设备的需求,而后对捕获的需求进行分解和分配,以获得航空电子系统的需求。在捕获航空电子系统需求时,利用预先划分的、组成飞机任务的子任务场景对广义驾驶舱系统需求进行捕获。根据机组与机器设备分配的约束条件和规则,将所捕获的需求分配给机组和包括航空电子系统在内的机器设备,再分配给航空电子系统与其它机器设备,从而捕获包括人机协作功能需求在内的航空电子系统的需求。在描述上述方法时还初步建立了一种描述需求分解和分配的数学模型。
The traditional demand capture method of the avionics system ignores the work done by the crew and the machinery and equipment and leads to the disconnection between the captured requirements and the man-machine interface requirements. The system that defines the unit and the equipment is a generalized cockpit system. By capturing the requirements of the system, crew functions, avionics capabilities and the requirements of other related equipment are obtained, and the captured requirements are then broken down and distributed to meet the needs of avionics systems. Capturing the requirements of the avionics system captures the needs of the generalized cockpit system using pre-defined subtask scenarios that make up the aircraft mission. The captured requirements are distributed to the crew and machinery including the avionics system according to the constraints and rules assigned by the crew and the machinery, and then distributed to avionics systems and other machinery and equipment to capture requirements including human-machine collaboration capabilities Demand for avionics systems. In describing the above method, a mathematical model describing demand decomposition and distribution is also initially established.
