Abstract: On the basis of analyzing and researching major links and influencing factors of each stage in the emergency management of oil & gasstorage and transportation enterprises, it is proposed to build 8 principles of emergency management, namely system principle, operabilityprinciple, cost effective principle, principle of compliance with laws and regulations, coordination principle, efficiency principle, uniquenessprinciple and principle of combination between normal management and non-normal management. The hierarchical structure of anevaluation index system is established, and FAHP is used to calculate index weights to build an overall evaluation index weight vectorsystem. The scores on the index at the lowest level from expert group is multiplied with the index weight and calculated to the highest levelsuccessively to obtain total scores, and finally, the evaluation is carried out by the success evaluation method. This evaluation method appliedin the monitoring and early warning of emergencies has certain guiding significance on the emergency management evaluation of oil & gasstorage and transportation enterprises.
