在工程质量管理中,采用因果关系图(石川图),把影响工程质量的主、次因素加以分类,在同一图上用箭头将其因果关系表示出来,然后召开质安会议,采取对策,制订切实可行的措施,解决质量问题。但是,该图本身仍限于定性地分析工程质量的因果关系,缺乏定量的描述,难以做到对影响工程质量的各种因素定量地评估。本文拟在工程质量管理的因果关系图的基础上,采用模糊数学的综合评估方法,分析质量问题产生的主要原因和次要原因,从局部到整体定量评估工程质量。由于借助数学关系,逻辑地
In the project quality management, using the causality diagram (Ishikawa diagram), the main and sub-factors that affect the quality of the project are classified. On the same figure, the causal relationship is indicated by an arrow, and then a safety and security conference is held to take countermeasures Practical measures to solve the quality problem. However, the figure itself is still limited to the qualitative analysis of the cause and effect of engineering quality, the lack of quantitative description, it is difficult to quantitatively assess the various factors that affect the quality of the project. Based on the causality diagram of engineering quality management, this paper intends to use the comprehensive evaluation method of fuzzy mathematics to analyze the main and secondary causes of quality problems and to quantitatively evaluate the quality of works from the local to the overall. Due to the help of mathematical relations, logically
