摘　　要：目前,大型企业信息系统规模和复杂度快速增长,但对故障的诊断分析仍主要依赖传统的人工经验,这不仅耗时、耗力,还影响对故障的及时处理。针对这一问题,创新性地提出了基于决策树的企业信息系统故障自动诊断分析方法,根据信息系统运行监控指标告警信息,实现对信息系统故障的自动诊断。利用某大型国有企业的实际生产运行数据,提取典型告警数据特征对该方法进行了验证,并在R语言环境下对决策树模型及其训练方法进行了仿真和对比分析。实验结果证明,该方法可以较为准确地实现故障自动快速诊断,有助于提高信息系统故障诊断分析效率。With the rapid growth of the scale and complexity of enterprise information systems, traditional fault diagnosis and analysis methods relying on human experiences and manual operations cost more and more labor and time. To solve this problem, an automatic algorithm was proposed. The algorithm exploits information from system operation monitoring indicators and alarm data, based on decision tree, to automatically diagnose and analyze faults of enterprise information systems. The algorithm was verified, and the decision tree model and training method was simulated and analyzed comparatively under R language environment, using alarm data extracted from real operation data of a typical large-scale enterprise system. The experiment results show that this algorithm is able to achieve fast automatic fault diagnosis accurately, and is much helpful on improving efficiencies of information system fault processing.
