Fuzzy Analytical Hierarchy Process for Ecological Risk Assessment

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.

The DPSIR Model for Environmental Risk Assessment of Municipal Solid Waste in Dar es Salaam City, Tanzania

“…More recently, it has been introduced in the field of environmental science, and is commonly termed as ERA. ERA refers to a scientific process that identifies and evaluates threats to the environment (comprising living organisms, their habitat and their ecosystem); this forms a part of the assessment of likelihood of potential hazards and their impacts, based on which risk mitigation measures can be undertaken [ 58 , 59 ] The ERA facilitates making of viable decisions for sustainable environmental management [ 60 , 61 , 62 ]. It has been confirmed a powerful tool for analyzing potential and extreme adverse environmental impacts, and has found to be with a wide application in decision-making processes [ 61 ].…”

Model Prioritas Program Pemerataan Ipm Di Provinsi Lampung Menggunakan Metode Analytic Hierarchy Process

“…MCDM dapat digunakan untuk mengevaluasi alternatif keputusan dan membantu pengambil keputusan dalam membuat tanggapan segera dan efektif di bawah tekanan dan ketidakpastian [14]. Permasalahan MCDM banyak ditemui pada sistem pemerintahan di berbagai negara [15]. Decission Support System (DSS) dirancang untuk menyelesaikan masalah pengambilan keputusan multi kriteria sehingga menjadi solusi bagi pemerintah dalam menentukan kebijakan pemerataan pembangunan.…”

Ranking Fuzzy Numbers with Fuzzy Analytical Hierarchy in Risk Assessment

“…As reported by Lee and Ph (2016), the conventional AHP is inadequate in dealing with the imprecise or vague nature of linguistic assessment, whilst in fuzzy AHP, common-sense linguistic statements have been used in the pair-wise comparison which can be expressed by the triangular fuzzy numbers (TFNs). As a result, the pair-wise comparisons and the integration of priorities are aggregated to determine the overall goals of the decision-making mechanism (Radionovs & Užga-Rebrovs, 2016).…”

“…Other studies by Hajjari and Numbers (2014) carried out a thorough review on the mathematical ranking method by various researchers (Baas & Kwakernaak, 1977;Liu & Han, 2005;Wang & Lee, 2007) and proposed new methods to overcome the mentioned weaknesses. In the area of natural sciences, Radionovs and Užga-Rebrovs (2016) analyse the ecological risk assessment towards human health using the fuzzy based technique.…”
