航天器软件质量度量模型研究与应用

Research and Application of Metrics Model for Spacecraft Software Quality

针对当前缺少通用的航天器软件产品质量度量方法、现有的方法难以表征和量化度量软件产品研制全过程的质量结果、难以根据质量度量结果开展针对性质量提升的问题,提出了一套通用的航天器软件产品研制过程质量度量模型。此模型对软件研制过程质量要素9项要求和28条子要求进行了质量定义,设置了质量度量评分标准,基于评分结果可对软件产品开展针对性的质量提升工作。该模型首次应用于嫦娥五号探测器软件产品研制,有效地支撑了嫦娥五号任务的圆满成功,对于航天器型号软件产品研制过程具有参考价值和借鉴意义。

A general metrics model for spacecraft software quality is established to solve the issue that the quality of spacecraft software development is difficult to be characterized with the current methods,and software quality improvement is difficult to be implemented pertinently because of a lack of such general metrics model.Nine requirements and twenty-eight sub requirements for software developing quality are defined in this model,quality metrics scoring criteria is set up,and software quality improvement can be implemented based on the scoring result.This model is applied in the software development process for Chang’e-5 lunar probe for the first time,which effectively supportes a complete success of Chang’e-5 mission.This model has great reference value and significance for the quality improvement of spacecraft software development process.
