摘　　要：危险与可操作性分析(HAZOP)是一种广泛应用于石化流程工业的危险分析方法。但人工HAZOP分析对分析人员要求较高,分析时易漏评、完备性差,且费时、费力、成本高。目前已有开发成功的基于SDG(符号有向图)的计算机自动HAZOP软件,但SDG方法难以得到后果的严重程度、发生概率和改进措施,无法替代专家的经验知识。针对这个问题,通过深入分析SDG-HAZOP与人工HAZOP的机理特点,提出了一种结合两者优点的计算机辅助半自动化HAZOP方法,经案例论证此方法兼具效率与完备性,具有较高的工程应用价值。HAZOP is a widely used industrial chemical process in risk analysis. However, the manual HAZOP analysis is time consuming, strenuous and costly. At present, a kind of computer-aided automatic HAZOP method based on sign directed graph (SDG) has been developed successfully. However, the SDG-HAZOP can’t get the risk-level,incidence and improvement measures got from the experts. For this problem, the mechanism of SDG-HAZOP and artificial HAZOP is analyzed in depth, and a computer-aided semi-automatic HAZOP method combining the advantages of SDG-HAZOP and artificial HAZOP was put forward. This method with high engineering application value can improve the efficiency and completeness of the HAZOP.
