Consistent Relative and Absolute Order-of-Magnitude Models

چکیده
The aim of this paper is to analyse under which conditions Absolute Order-of-Magnitude and Relative Orderof-Magnitude models may be consistent and to determine the constraints which guarantee consistency. A graphical interpretation of the constraints is provided, bridging the absolute qualitative labels of two quantities into their corresponding relative relation(s), and conversely. The ROM relations are then characterized in the absolute order-of-magnitude world.

On the relative efficiency in general network structures
Data Envelopment Analysis (DEA) is an eciency measurement tool for evaluation of similar Decision Making Units (DMUs). In DEA, weights are assigned to inputs and outputs and the absolute eciency score is obtained by the ratio of weighted sum of outputs to weighted sum of inputs. In traditional DEA models, this measure is also equivalent with relative eciency score which evaluates DMUs in compar...
متن کاملTesting the four models for prediction of gully head advancement (case study: Hableh Rood basin- Iran)
Gully erosion is one of the most complicated and destructive forms of water erosion. In order to prevent this erosion, the important factors advancing gully head must be recognized. Nowadays, several models have been proposed in measuring gully head advancement and identifying the severity of erosion. These models must be calibrated for each country to see whether they are applicable or not. So...
متن کاملDual tableau for a multimodal logic for order of magnitude qualitative reasoning with bidirectional negligibility
The use of models to represent different scientific and engineering situations leads to qualitative reasoning as a good possibility when the traditional numerical methods are limited. Qualitative Reasoning (QR) provides an intermediate level between discrete and continuous models. A form of QR is to manage numerical data in terms of orders of magnitude (see, for example, [12, 14]). Two approach...
متن کاملFuzzy Risk Analysis Based on Ranking of Fuzzy Numbers Via New Magnitude Method
Ranking fuzzy numbers plays a main role in many applied models inreal world and in particular decision-making procedures. In manyproposed methods by other researchers may exist some shortcoming.The most commonly used approaches for ranking fuzzy numbers isbased on defuzzification method. Many ranking fuzzy numberscannot discriminate between two symmetric fuzzy numbers withidentical core. In 200...
متن کاملEffects of Absolute and Relative Sunk Costs on the Decision to Persist with a Course of Action
Two experiments were designed in order to examine how D. Kahneman and A. Tversky’s (1979, 1984) assertions from prospect theory, that mental accounts are organized topically, might relate to sunk cost effects in decisionmaking. In each experiment, the absolute magnitude (dollars) and the relative magnitude (dollars in proportion to an overall project budget) of sunk costs were manipulated indep...
