AbstractThe purpose of this paper is to implement a methodology based on stakeholder’s judgment with assistance of fuzzy Multi-Criteria Decision Analysis (MCDA) methods to assess the environmental impact. Fuzzy Analytic Hierarchy Process (FAHP) is used as a multi-level decision-making tool taking into consideration human evaluation; it captures the vagueness in ordinal judgments obtained from s...

This paper proposes an optimization model of life cycle cost (LCC) of the transformer. First, to build the model of LCC of the transformer, the whole LCC of the transformer is divided into five costs, i.e., initial cost, operating cost, maintenance cost, fault cost and disposal cost. The whole LCC is calculated. Second, according to the data of several kinds of transformers, the relationship be...

Based on features of distance education and its disadvantages in terms of learning evaluation, this study uses Analytic Hierarchy Process (AHP) and fuzzy mathematics theory to study distance education. First, an electric file is generated for each learner. Then a practical multi-hierarchy evaluation model is built based on AHP. Finally, evaluation of on-line education is done based on informati...

This paper presents a structured methodology for Information Systems (IS) outsourcing decision problem. The problem of selection among candidate information systems of the IS can be formulated as Multi criteria decision making (MCDM) techniques. Thus, this paper proposes a fuzzy group decision making process to evaluate and select the appropriate Information System Project (ISP) based on fuzzy ...

In order to comprehensively evaluate the employee satisfaction of mine occupational health and safety management system, an analytic method based on fuzzy analytic hierarchy process and 2-tuple linguistic model was established. Based on the establishment of 5 first-grade indicators and 20 second-grade ones, method of improved AHP and the time-ordered Weighted Averaging Operator (T-OWA) model is...

Aiming at configuration design for mass customization, this paper develops a fuzzy ranking methodology for concept evaluation. The fuzzy preference relation is applied to modeling the fuzziness on the level of a single criterion as well as on a global level. The ranking approach integrates linguistic terms and fuzzy numbers into the fuzzy preference model so as to characterize both intangible a...

Most of the real-world multi-criteria decision-making (MCDM) problems contain a mixture of quantitative and qualitative criteria; therefore quantitative MCDM methods are inadequate for handling this type of decision problems. In this paper, a MCDM method based on the Fuzzy Sets Theory and on the Analytic Hierarchy Process (AHP) is proposed. This method incorporates a number of perspectives on h...
