Summary: | The invention provides a chemical enterprise mechanical injury accident safety risk early warning method comprising the following steps: carrying out safety risk influence analysis on cases in a mechanical injury accident case library to obtain a safety risk influence analysis result; constructing a chemical machinery damage fault tree based on the safety risk influence result; converting the fault tree into a Bayesian network structure through a mapping method; through a Noisy or Gate model, determining a conditional probability that a chemical machinery damage fault tree or gate node is converted into a node in a Bayesian network structure; establishing a chemical enterprise mechanical injury accident risk early warning model according to the conditional probability; key risk management and control are carried out through the chemical enterprise mechanical injury accident risk early warning model, and a prevention and control scheme is provided. According to the method, quantitative analysis and evaluation |
