【摘要】 针对单纯利用LEC方法对作业系统危险因素的风险程度进行评价的缺点,对影响危险源风险评价的主要因素进行深入地分析,结合LEC与AHP评价方法,充分利用事故案例和专家经验,对诸危险因素实施关联分析,设计模糊评价指标的合理权重,从而确定危险因素导致事故的重要程度。通过统计数据的验证,该方法更客观地实现定量评价,反过来有效保证评价结果与统计数据的一致性。更多还原

【Abstract】 Based on the defects of simply using LEC method to evaluate work system risk extent,the authors deeply analyze the main factors which influence the risk extent.By adopting LEC and AHP assessment methods with the combination of the former accident cases and experts’ experiences,associating multiple factors that inducing to the occurrence of accidents,authors design the reasonable weight right,thus confirm the important order of the indexes.The statistical data verifies that above method implements the quantitative assessment objectively,so that effectively guarantees the consistency of the evaluation and statistical data.更多还原
