Abstract
Being able to evaluate risks is an important task in many areas of human activity: economics, ecology, etc. Usually, environmental risk assessment is carried out on the basis of multiple and sometimes conflicting factors. Using multiple criteria decision-making (MCDM) methodology is one of the possible ways to solve the problem. Analytic hierarchy process (AHP) is one of the most commonly used MCDM methods, which combines subjective and personal preferences in the risk assessment process. However, the AHP involves human subjectivity, which introduces vagueness type of uncertainty and requires the use of decision making under those uncertainties. In this paper, work with uncertainty is considered using fuzzy-based techniques. The paper also analyses the ecological risk assessment towards human health in case of gaseous substance escape at a chemical factory using the fuzzy analytical hierarchy process.
Highlights
Risk management is an integral part of environmental risk analysis
Environmental risk assessment, among the other tasks, includes making decisions that involve the choice of alternatives on the basis of multiple and sometimes conflicting factors
The main goal of this paper is to quantify the effect of multiple risk factors in the ecological risk assessment process
Summary
Risk management is an integral part of environmental risk analysis. This is the process of weighing the alternatives (options), choosing the most appropriate action, integrating engineering, social and economic data into risk assessment results.Usually, the environmental risk assessment process includes objective data, while the risk management includes the preferences and attitudes that have both objective and subjective elements [1].
