Chemical process industry is a high risk industry which can result in catastrophic casualties, loss of properties, and environment damage. Process safety should always come first in the chemical process industry. Researchers have made great efforts to make the chemical process industry safer for people and the environment. Effective process safety management is the guarantee for process safety....

Chemical Process Plant as a complex system requires good scientific knowledge on different issues including Process Safety Analysis (PSA). Fuzzy logic is the collective name for “Fuzzy set analysis” and “Possibility theory”, able to use random or approximate data in the Process Safety Analysis. This paper explains the impact of fuzzy set theory for basic tools used in Process Safety Analysis. I...
