民用飞机需求变更管理研究

Research on Requirements Change Management of Civil Aircraft

现代民用飞机项目采用基于需求的研发流程,在整个项目进展过程中,需求变更不可避免。作为设计的输入,需求的变更可能带来重大项目风险,因此需求变更管理在民用飞机项目中至关重要。本文解析了需求变更、需求工程与构型管理之间的关系,提出了根据成熟度实施需求变更控制的思想,给出了需求变更的流程,为工程人员更为深刻的认识需求变更具有指导意义。

Requirements-based development is applied in modern civil aircraft programs, within which, requirements change is inevitable. While requirements change may cause critical risks to a program, the management of requirements change is significant during aircraft design. The differences among requirements change, requirements engineering and configuration management were explicated, an idea to implement requirements change based on requirements maturity was proposed, and requirements change process was provided, which are beneficial for engineers to better understand requirements change.
