INTEGRATED HAZOP-EVIDENCE THEORY-ANT COLONY ALGORITHM MODEL FOR SAFETY ASSESSMENT AND ITS APPLICATION

摘要：

In complex system, most of single faults have multiple propagation paths, so any local slight deviation can propagate, spread, accumulate and increase through fault causal chain, which will finally result in catastrophic accidents. Considering the randomness, complexity and uncertainty of fault propagation, a new integrated HAZOP-DS-AC safety assessment model is proposed, integrating the advantages of HAZOP theory, D-S evidence theory and ant colony algorithm, in order to improve the reasonableness and accuracy of safety assessment. Taking gas turbine compressor system as an example for safety assessment based on HAZOP-DS-AC model, the root cause and risk estimation of faults are determined by reasoning in the situation of multi observable deviations in the field case study, and the proposed model is proven to be beneficial to guarantee the long period safety operation of system.
