Our objective here is to obtain quality-fused values from multiple sources of probabilistic distributions, where quality is related to the lack of uncertainty in the fused value and the use of credible sources. We first introduce a vector representation for a probability distribution. With the aid of the Gini formulation of entropy, we show how the norm of the vector provides a measure of the c...

We explore a framework for argumentation (based on classical logic) in which an argument is a pair where the first item in the pair is a minimal consistent set of formulae that proves the second item (which is a formula). We provide some basic definitions for arguments, and various kinds of counter-arguments (defeaters). This leads us to the definition of canonical undercuts which we argue are ...

The aim of this contribution is to present the concept of unipolar parametric evaluation of aggregation functions, and unify the ideas of global and local unipolar parametric evaluations. We show that several well–known parameters introduced in special classes of aggregation functions are included in this framework, and we also propose some new parameters for aggregation functions.

In this contribution we propose a method for generating OWA weighting vectors from the individual assessments on a set of alternatives in such a way that these weights minimize the disagreement among individual assessments and the outcome provided by the OWA operator. For measuring that disagreement we have aggregated distances between individual and collective assessments by using a metric and...

This paper investigates the optimization problem of multi-product aggregate production planning (APP) with fuzzy data. From a comprehensive viewpoint of conserving the fuzziness of input information, this paper proposes a method that can completely describe the membership function of the performance measure. The idea is based on the well-known Zadeh’s extension principle which plays an importan...

considering iran geographical location, water is the most limited factor in agriculture section. therefore, it would be logical to consider water as one of the most significant criteria in selection of cultivation model. the purpose of this study is assigning cultivation pattern based on economic value of water in gotvand township in agronomic year 2008-2009. so it was necessary to computes the...

abstract in order to optimize the water management in agriculture in semi arid and arid conditions water-salinity function should be evaluated. in order to evaluate salinity and deficit irrigation two experiments were conducted in 2008 and 2009. kochia was grown with six levels of saline water (1.5, 7, 14, 21, 28, and 35 ds/m) and three levels of applied water (25, 75, and 125 percent of the wa...

We propose the concepts of superadditive and of subadditive transformations of aggregation functions acting on non-negative reals, in particular of integrals with respect to monotone measures. We discuss special properties of the proposed transforms and links between some distinguished integrals. Superadditive transformation of the Choquet integral, as well as of the Shilkret integral, is shown...
