EN Process risk assessment is the most effective way to design safety and security safeguards in order to ensure the safety of people and the environment. The key issue is to estimate the frequency of occurrence and consequences as well as the risk of major accident scenarios with the lowest level of uncertainty. In order to deal with all knowledge-based uncertainties a new process risk assessment methodology based on fuzzy logic was proposed. The methodology utilized the fuzzy representative loss events selection model, the fuzzy bow-tie model and the fuzzy risk matrix. The case study for isobutane storage tank was used to illustrate the proposed methodology. Preliminary tests confirmed that final results of the risk index of accident scenarios were determined in a more precise and realistic manner and more appropriate selection of safety systems can be achieved.
