In this study, we proposed a Fuzzy and AHP (Analytic Hierarchy Process)-based negotiation support mechanism (FAHP-NEGO) to support the dynamic negotiation in Electronic Commerce (EC). Most of former researches proposed the negotiation support mechanisms, which were based on quantitative conditions only. In real-world case, however, it was crucial to have qualitative negotiation conditions such ...

This study uses the fuzzy analytical hierarchy process (FAHP) method to prioritize contracting methods determine most suitable contract option for water and wastewater projects (WWP). Content analysis, a two-round Delphi survey technique, series of validation reliability tests helped establish 18 key criteria FAHP analysis. Consequently, data collected from experts through pairwise comparison q...

The main objective of the present study was to prioritize the allocation of water resources of Chahnimeh reservoirs from economic, social, and environmental perspectives in 2015-2016 season using fuzzy analytic hierarchy process (FAHP) and fuzzy technique for order preference by similarity of an ideal solution (FTOPSIS) as the branches of fuzzy multiple-criteria decision-making (MCDM) models. D...

The material plays an important role in an engineering design process. The suitable material selection for a particular product is one of the vital tasks for the designers. In order to fulfil the product’s end requirements, designers need to analyze the performance of various materials and spot suitable materials with precise functionalities. Due to the presence of large number of materials wit...

A systematic study of the optional maintenance strategies of the Transformer is conducted and a set of general factors which should be considered in the maintenance strategies is established. A Fuzzy Analytic Hierarchy Process (FAHP) based on the goal programming is proposed in view of the defects of the traditional Fuzzy Analytic Hierarchy Process (FAHP), and the specific application process o...

Ranking of companies listed on the exchange represent their status and considered a criterion for investment. Also, it increases market's competition, development and efficiency. In this study, the fifty superior companies listed in Tehran Stock Exchange were ranked based on financial ratios (liquidity, operational, leverage and profitability) using FAHP- FTOPSIS hybrid approach during the year...

In this study, a new modeling method based on trapezoidal fuzzy number FAHP has been proposed to solve the problem of risk element transmission in enterprise project evaluation chain. We firstly put forward enterprise project chain risk element transmission and constructs enterprise project chain risk element transmission tetrahedron model and then proposed the theory of enterprise project eval...

In today’s competitive environment evaluating firms’ performance properly, is an important issue not only for investors and creditors but also for the firms that are in the same sector. Determining the competitiveness of the firms and evaluating the financial performance of them is also crucial for the sector’s development. The aim of this study is developing a fuzzy model to evaluate the perfo...

This paper presents the procedure for logistics system scenario selection for the central business district (CBD) of the city in the phase of significant urban changes. Scenarios are defined in accordance with the overall logistics concept of the city. Conflicting goals of stakeholders (residents, shippers and receivers, logistics providers and city government) generate a vast number of criteri...

In order to safeguard the safety of passengers and reduce maintenance costs, it is necessary to analyze and evaluate the security risk of the Railway Signal System. However, the conventional Fuzzy Analytical Hierarchy Process (FAHP) can not describe the fuzziness and randomness of the judgment, accurately, and once the fuzzy sets are described using subjection degree function, the concept of fu...
