The eigenvector method (EM) is well-known to derive information from pairwise comparison matrices in decision making processes. However, this method is logically incomplete since its actual numerical error is unknown and its reliability is doubted by such phenomena as “right-left asymmetry”, “rank reversal”, and reversal of “order of intensity of preference”. In this paper, we associate EM with...

This paper presents a new, nonlinear, multicriteria, decision-making method: the characteristic objects (COMET). This approach, which can be characterized as a fuzzy reference model, determines a measurement standard for decision-making problems. This model is distinguished by a constant set of specially chosen characteristic objects that are independent of the alternatives. After identifying a...

Due to dynamic nature of current software development methods, changes in requirements are embraced and given proper consideration. However, this triggers the rank reversal problem which involves re-prioritizing requirements based on stakeholders’ feedback. It incurs significant cost because of time elapsed in large number of human interactions. To solve this issue, a Semi-Automated Framework f...

In this paper, a decision model based on a fuzzy soft set and ideal solution approaches is proposed. This new decision-making method uses the divide-and-conquer algorithm, and it is different from the existing algorithm (the choice value based approach and the comparison score based approach). The ideal solution is generated according to each attribute (pros or cons of the attributes, with or w...

The effect of theta pulse stimulation (TPS) on pentylenetetrazol (PTZ)-induced long-term potentiation of population spikes (PS) was studied in the hippocampal CA1 in vitro. A transient PTZ application produced a long-lasting enhancement of PS amplitude. A 3-min episode of TPS delivered at a higher intensity produced complete reversal of the PTZ potentiation when delivered during the last minute...

trichotillomania refferes compulsive hair pulling that results in considerable hair loss.many medical and nonedical therapies have been applied for treatment of this disorder. the purpose of this study was to compare the efectiveness of clomipramine, hydroxyzine, and behavior therapy (habit reversal) in the treatment of trichottillomania. to achieve this 15 patients with trichotillomania were r...

We prove that the filling order is quadratic for a large class of solvable groups and asymptotically quadratic for all Q-rank one lattices in semisimple groups of R-rank at least 3. As a byproduct of auxiliary results we give a shorter proof of the theorem on the nondistorsion of horospheres providing also an estimate of a nondistorsion

Abstract Rank reversal in Analytic Hierarchy Process (AHP) due to introduction or removal of a new alternative is well documented literature. However, rank the aggregation benefit and cost criteria has not been addressed with requisite rigour. This paper demonstrates type AHP which can arise method (ratio difference) approach (sum 1 sum 2) used aggregate criteria. Numerical examples, mathematic...
