ارزیابی ریسک کمی از واحدهای رگازشاری شناور متوسط ​​با استفاده از مدل سلسله مراتبی سیستم

It was found that the qualitative risk assessment had a tendency to overestimate the frequency of the accidents but to underestimate their consequence, while the quantitative risk assessment based on the result of the qualitative assessment inherently underestimated both the frequency and the consequence of hazards. The hierarchical modelling was found to be an excellent method of dealing with complex systems with short operational history.
