اظهر المزيد [+] اقل [-]Environmental risk assessment is an essential element in any decision-making process in order to minimize the effects of human activities on the environment. Unfortunately, often environmental data tends to be vague and imprecise, so uncertainty is associated with any study related with these kind of data.
اظهر المزيد [+] اقل [-]Essentially, uncertainty in risk assessment may have two origins – randomness and incompleteness. There are two main ways to deal with these uncertainties – probability theory and fuzzy logic.
اظهر المزيد [+] اقل [-]Probability theory is based on a stochastic approach, using probability functions to describe random variability in environmental parameters.
اظهر المزيد [+] اقل [-]Fuzzy logic uses membership functions and linguistic parameters to express vagueness in environmental issues.
اظهر المزيد [+] اقل [-]We discuss the best way to deal with uncertainties in the environmental field and give examples of probabilistic and fuzzy-logic approaches applied to environmental risk assessment.
