在实际的机载软件研发过程中，衍生需求既可以存在于描述“什么（WHAT）”功能的软件高级别需求中，也可以存在于描述“如何（HOW）”实现的软件低级别需求中。如果将衍生需求置于较低层级的需求中会造成受影响方（如系统工程师）无法得到足够的信息，从而导致向上和向下的追溯性问题。本文提出了一套准则，用以最优化DO-178C中定义的衍生需求的分配。在实际工程中，该准则可以正确合理地定义衍生需求以确保信息的追溯性和可见性。

Software derived requirements can be software high level requirements to describe the “what” or software low level requirements to describe the “how”. This study proposed a set of criteria for optimal allocation of derived requirements as deifned by DO-178C. In actual engineering, these criteria can be used to rationally deifne derived requirements to ensure the traceability of the requirements and the visibility of the information.
