Mission reliability design trade-off approach for civil aircraft

The iterative assignment of mission reliability Index is an important part of the civil aircraft design process, and there are two kinds of trade-offs in the design process: the trade-offs between hardware-level metric assignment and system architecture design, and the trade-offs in the assignment of reliability Index at both the hardware level and the functional level, and this paper carries out a study on the trade-offs in civil aircraft mission reliability design.
