A ship’s crew plays an important role in the maritime transportation sector and their performance is paramont in the shipping industry. On this account, an impartial evaluation of the crew’s performance is an important issue. In this paper, the ship officer’s performance evaluation problem is studied. The performance evaluation criteria that shipping companies take into account are determined a...

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...

This paper conducts a comparison analysis of some of the most common defuzzification techniques which helps rank fuzzy weights calculated from fuzzy comparison matrices through Fuzzy Analytic Hierarchy Process. Ranking of weights calculated through FAHP algorithms is of critical importance as it directly effects the decision making process. More so ranking of fuzzy numbers is also important in ...

since we cannot manage what we cannot control, and we cannot control what we do not measure, the measurement of knowledge management (km) effectiveness is a very important issue. this study aims at developing a methodology to evaluate the km effectiveness under fuzziness in research organizations. in order to develop such a methodology and to define measures of km effectiveness, first the relev...

This paper proposes a new method for finding fuzzy weights in the fuzzy analytic hierarchy process (FAHP), which fuzzifies the derived formulation of an eigenvector directly. The presented formulation only needs information about the upper triangular matrix and the assumption about the reciprocal matrix is not necessary. This characteristic makes the FAHP feasible because the property of recipr...

Most decision-making and problem-solving tasks are too complex to be understood quantitatively. People perform such tasks using knowledge that is imprecise rather than precise. This study presents consistent fuzzy linguistic preference relations rather than fuzzy analytic hierarchy process (FAHP) to select computer integrated manufactory (CIM) systems. The proposed method yields decision matric...

Every complex problem now days require multicriteria decision making to get to the desired solution. Numerous Multi-criteria decision making (MCDM) approaches have evolved over recent time to accommodate various application areas and have been recently explored as alternative to solve complex software engineering problems. Most widely used approach is Analytic Hierarchy Process that combines ma...

Warehouse location selection is a multi-criteria decision problem including both quantitative and qualitative criteria and has a strategic importance for many companies. The conventional methods for warehouse location selection are inadequate for dealing with the imprecise or vague nature of linguistic assessment. To overcome this difficulty, fuzzy multi-criteria decision-making methods are pro...
