Activity safety risk assessment method, system and equipment

The invention provides an activity safety risk assessment management method. The activity safety risk assessment method comprises the following steps: a risk identification step; a risk analysis step; and a risk evaluation step. The risk analysis step further comprises the following steps: executing multi-level layering according to the properties of the risk factors to form risk factor classification subsets at all levels; determining a single risk evaluation index and a weight thereof in the risk factor classification subset of each level, wherein the risk evaluation step further comprises the following steps of: determining a risk quantity value of each layered single risk factor classification subset; executing total risk score calculation; and executing security risk grade evaluation according to the total risk score. 本发明提供了一种活动安全风险评估管理方法，该活动安全风险评估方法包括以下步骤：风险识别步骤；风险分析步骤；以及风险评价步骤；其中该风险分析步骤还包括步骤：根据风险因素的性质执行多级分层，形成各级风险因素分类子集；以及确定各级层风险因素分类子集内单项风险评价指标及其权重；其中该风险评价步骤还包括步骤：确定分层后的各单项风险因素分类子集的风险量值；执行总风险分值计算；以及根据总风
