摘　　要：以DO-178B/C软件重用标准为基础,将先前开发软件分为已通过和未通过适航合格审定的PDS,构建了PDS软件的评估准则和评估方法,将PDS的评估结果与标准进行对照,能够快速定位PDS的重用要求和应采取的过程活动。实践表明,通过重用已通过适航合格审定的PDS软件的部分数据,可以有效提升软件开发效率。针对未通过适航合格审定的PDS软件重用,本文也提供了一种差距分析方法,对照分析PDS软件与目标要求的差距,用以评估所需的额外工作量。Based on the DO-178B/C software reuse standard,previously developed software is divided into PDS that has passed the airworthiness certification and PDS that has not passed the airworthiness certification,and evaluation guidelines and evaluation methods for PDS is constrycted.By comparing the evaluation results with the standard,the reuse requirements of PDS and the process activities to be taken can be quickly located.The reuse practice shows that by reusing datum of the PDS that has passed the airworthiness certification,it can effectively improve the software development efficiency.A gap analysis method is also provided for the reuse of PDS that has not passed airworthiness certification,in which the gap between the PDS software and the target requirements is analyzed to assess the additional workrequired.
