To solve the uncertainty and complexity problems in hazardous chemical storage risk assessment, this paper constructs the evaluation index system and proposed the risk assessment model based on AHP-fuzzy comprehensive evaluation approach, which organically integrate the quantitative and the objectively of the analytic hierarchy process (AHP) and the inclusive advantage of fuzzy comprehensive ev...

Financial problems have been the subject of much research. A widely used approach in recent work on these problems is the use of fuzzy set theory, where fuzzy terms are used to model the uncertain environments. The purpose of this work is to combine the fuzzy analytic hierarchy process (AHP) with the portfolio selection problem. More specifically, the decision-making problem is to decide which ...

This study recommends a GIS-based (Geographic Information Systems) and multi-criteria evaluation for site selection of gas power plant in Natanz City of Iran. The multi-criteria decision framework integrates legal requirements and physical constraints related to environmental and economic concerns. It also builds a hierarchy model for gas power plant suitability. The methodologies used for site...

The recent government tendering process being conducted in an electronic way is becoming an inevitable affair for numerous governmental agencies to further exploit the superiorities of conventional tendering. Thus, developing an effective web-based bid evaluation methodology so as to realize an efficient and effective government E-tendering (GeT) system is imperative. This paper firstly investi...

Analytic hierarchy process (AHP) is a utility theory based decision-making technique, which works on a premise that the decision-making of complex problems can be handled by structuring them into simple and comprehensible hierarchical structures. However, AHP involves human subjective evaluation, which introduces vagueness that necessitates the use of decision-making under uncertainty. The vagu...

The Analytic Hierarchy Process (AHP) proposed by T. L. Saaty has been widely used in decision making. Inner dependence method AHP is used for cases in which criteria or alternatives are not independent enough and using the original AHP or inner dependence AHP may cause results to lose reliability because the comparison matrix is not necessarily sufficiently consistent. In such cases, fuzzy repr...

Previous review papers on analytic hierarchy process (AHP) and TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) mainly focused on the application areas and paid scant attention to the framework development of AHP, TOPSIS and their hybrid methods. The purpose of this paper is to review the literature on analytic hierarchy process (AHP), type of scale used in AHP, modified ...

the aim of this study is to evaluate the obstacles due to a dpsir model combined with fuzzy analytic hierarchy process technique. hence, to prioritize the responses regarding the driving forces, pressures, states and impacts, the hierarchy of the model is established. evaluations and prioritization of model results of urban transport situation in tehran have provided a number of necessary issue...

Caixia Li , Sreenatha Gopalarao Anavatti, Tapabrata Ray University of New South Wales @ Australian Defence Force Academy [email protected] Abstract-This paper focuses on the design and implementation of the analytical hierarchy process (AHP) using Fuzzy inference techniques. This AHP-FUZZY approach is a multi-criteria combination system. The nature of the AHP-FUZZY approach is pair-...

To overcome the difficulty in understanding quantitative evaluation on actually safety assessment, This research proposed a qualitative comprehensive assessment method of fuzzy state based on fuzzy Analytic Hierarchy Process (AHP) and Fuzzy Transform. First of all, the fuzzy comment of multiple assessments by experts should focus on the quantitative evaluation of corresponding triangular fuzzy ...
