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 ...

‎in this paper, we present a two-stage model for ranking of decision making units (dmus) using interval analytic hierarchy process (ahp). since the efficiency score of unity is assigned to the efficient units, we evaluate the efficiency of each dmu by basic dea models and calculate the weights of the criteria using proposed model. in the first stage, the proposed model evaluates decision making...

This paper proposes a two-stage fuzzy logarithmic preference programming with multi-criteria decisionmaking, in order to derive the priorities of comparison matrices in the analytic hierarchy pprocess (AHP) and the analytic network process (ANP). The Fuzzy Preference Programming (FPP) proposed by Mikhailov and Singh [L. Mikhailov, M.G. Singh, Fuzzy assessment of priorities with application to c...

abstract purpose of this paper: the objectives of this paper are two folds: (1) utilizing hierarchical fuzzy technique for order preference by similarity to ideal solution (topsis) approach to evaluate the most suitable rfid-based systems decision, and (2) to highlight key risks and benefits of radio frequency identification technology in healthcare industry. design/methodology/approach: resear...

The evaluation of travel website service quality (TWSQ) is a multiple criteria decision making (MCDM) problem and has a strategic importance for those travel-related commercial companies. In practical environments, a decision-maker (DM) faces a variety of TWSQ that is often vague from human beings’ subjective judgments. The conventional methods for the evaluation of TWSQ are inadequate for deal...

After the high-voltage transmission line is cut off due to a fault, bearing power will be transferred, which may cause overload. If overload cannot eliminated quickly and scientifically, it very likely that backup protection activated, trigger chain trip or even blackout accidents. In view of this, this paper proposed cross-voltage level optimization load shedding control strategy based on fuzz...
