摘　　要：软件密集型装备是武器装备发展的一个趋势。软件过程改进是提升嵌入软件的生产效率和质量的一种有效的改进手段。对于单个软件过程的控制和分析，由于传统Shewhart控制图无法区分其他过程对单个过程的影响，通过把系统因素进一步细分为外部系统因素和内部系统因素，使用选控图来隔离外部系统因素，实现对单个软件过程的独立分析。基于Petri网理论、故障树技术和模糊集理论，建立了适用于软件过程故障诊断的模糊Petri网模型。在此基础上提出针对单个软件过程的过程度量、控制、分析和改进框架。应用实例说明，在一定程度上，能够通过过程控制提升软件密集型装备的质量和生产效率。Software-intensive equipments will play more and more important role in future wars, but unfortunately, the productivity and quality of the embeded software is being a prominent issue unsolved, software process improvement has been proved to be an effective solution. For a single software process. Shewhart control charts cannot define the effect from other processes, we refine system causes into outer system causes and inner system causes, and use Select Cause Chart to control them, so that a single software process can be analyzed independently. Based on the theory of Petri net, fault tree techniques and theory of fuzzy sets, we establish a fuzzy Petri net, which is used for fault diagnosis of single software process. Based on the above theories, we bring forward a framework of measuring, controlling, analyzing and improving single software process.
