航天飞行软件复杂性研究综述

A Review of the Complexity of Aerospace Flight Software

近年来,随着航天飞行任务的发展,系统中飞行软件规模和功能占比突飞猛进,飞行软件越来越复杂,降低软件复杂性的质量需求凸显,软件复杂性成为系统难以解决的困难,造成软件质量、成本、进度问题,影响航天产品的可靠性、安全性,给航天系统任务成功带来巨大的风险。基于当前国内外航天飞行软件复杂性的研究现状,分析飞行软件复杂性内涵,从软件需求、开发方法、系统架构、软件验证与集成和组织管理方面探讨飞行软件复杂性的应对策略,最后展望飞行软件复杂性的发展。

In recent years,with the development of space mission,the scale and function of flight software in the system are advancing by leaps and bounds,the complexity of flight software becomes more and more complex.To reduce the complexity of software quality needs to be highlighted,and the complexity of software becomes difficult to overcome,which leads to the problems of lower software quality,high cost and long schedule,affects the reliability and safety of aerospace products,and brings great risks to the success of space system mission.This paper reviews the research status of space flight software complexity at home and abroad,analyzes the connotation of flight software complexity.From the aspects of software requirements,development methods,system architectures,software verifications and integrations,organization managements,the paper discusses the coping strategies of flight software complexity,and finally looks forward to the development of flight software complexity.
