基于DO-178C的机载软件质量保证与管理

DO-178C 作为机载软件适航可接受的符合性标准，明确要求机载软件综合过程中必须包含软件质量保证（SQA）过程。以机载软件的软件生命周期定义、过程和数据为基础，从目标、活动和符合性评审三个方面分析基于DO-178C 的软件质量保证过程的实施；结合软件项目质量管理技术和工具，从规划软件质量管理、管理软件质量和控制软件质量三个过程研究基于DO-178C 的软件质量管理方法并给出工程实践建议。结果表明：本文将软件质量保证与质量管理紧密结合，形成了适航要求的相关证据，提供了符合需求的民用机载软件，有效保证了机载软件的质量和持续改进措施。

Airborne Software Quality Assurance and Management Based on DO-178C

DO-178C clearly requires that the software quality assurance (SQA) process must be included in the airborne software integration process as an acceptable compliance standard for airborne software airworthiness. Based on the software life cycle definition, process and data of airborne software, this paper analyzes the implementation of the software quality assurance process based on DO-178C from the three aspects of objectives, activities, and compliance review. With software project quality management techniques and tools, the DO-178C-based software quality management method is explored from the three processes of planning software quality management, managing software quality, and controlling software quality, and some practical engineering suggestions are given. By using both software quality assurance and quality management, evidence of airworthiness requirements can be generated to provide confidence in civilian airborne software that meets the requirements, effectively ensuring its quality and continuous improvement.
