Research on Event Ontology Model Based on Customs Laboratory Accident Deduction
To improve the safety management of customs laboratories,the application of event ontology model is studied,and an event ontology model suitable for accident deduction in customs laboratories is constructed.At first,the five basic accident factors of staff,event,time,place,object are extracted to construct a simple five-tuple.And then the bow tie structure is used to deduce the causes,the processes and the consequences of the accident.Finally,the model is sustainably improved through the control measures of patrol,handle,supervise.After analyzing the accident deduction in a custom laboratory,this model can timely identify and eliminate the laboratory risks,effectively ensuring the security of persons and property.The model can deduce the three stages before,during,and after an accident,mapping the two factors of staff and object in a bowtie structure.In comparison,the model has the advantages of clear division for basic accident factors,easy-to-understood for the model content,concise judgment and sustainable improvement.
