Fuzzy mathematical safety evaluation model and application for storage tank district of petrochemical enterprises

at the characteristics of fire explosion accidents occurred in the storage tank district of petrochemical enterprises,fuzzy comprehensive evaluation was suggested since the safety system for the storage tank district involves multiple factors and multiple layers.After analyzing all factors influencing the safety of storage tank district from five as- pects,a more rational fuzzy math evaluation system was established by analyzing the connections between all the factors. The weight of the safety factors were developed by using the AHP,and a fuzzy math evaluation model was established. Finally,this evaluation technique was put into practice,and get a good result was obtained.It is indicated that this mod- el has real practicability.
