| 摘 要： | 鉴于风险识别的方法大多以定性为主而缺乏客观评价的状况,提出了一种基于故障树分析和粗集理论的风险识别方法。利用故障树分析可以全面系统地找出影响燃气管道安全的各种因素,借助粗集理论中的属性约简算法对这些因素进行属性约简,最终识别出影响城市燃气管网的风险因素,可以为风险分析评价提供必要的依据。 |
| 关 键 词： | 城市燃气管网 风险识别 故障树分析 粗集理论 属性约简 |

| Abstract: | A new method based on fault tree analysis and rough set theory to identify risk is proposed aiming at the status that qualitative analysis prevails over present risk identifications mostly, which lacks objective evaluation. After all possible factors influencing pipeline security are discovered by means of fault tree analysis,attribute reduction may be carried out using attribute reduction algorithm in rough set theory,and finally all risk factors influencing urban gas pipeline security are identified. The method will provide essential basis for risk analysis and appraisal. |
| Keywords: | urban gas pipelines risk identification fault tree analysis rough set theory attribute reduction |
