In the framework of multicriteria decision making based on Choquet integrals, we present a maximum entropy like method enabling to determine, if it exists, the least specific capacity compatible with the initial preferences of the decision maker.

The original rough set approach proved to be very useful in dealing with inconsistency problems following from information granulation. It operates on a data table composed of a set U of objects (actions) described by a set Q of attributes. Its basic notions are: indiscernibility relation on U, lower and upper approximation of either a subset or a partition of U, dependence and reduction of att...

BACKGROUND Priority setting in population health is increasingly based on explicitly formulated values. The Patients Rights Act of the Norwegian tax-based health service guaranties all citizens health care in case of a severe illness, a proven health benefit, and proportionality between need and treatment. This study compares the values of the country's health policy makers with these three off...

Data Centers (DCs) are complex organizational and technical infrastructures that assure the performance and reliability of modern information and communication systems. The high installation and operations costs of DCs and the stringent requirements regarding reliability and safety require a close attention to the location of this type of facility. This paper proposes a Multi-Criteria Decision ...

Recent research has recognised that multicriteria decision making (MCDM) should take account of uncertainty, risk and confidence. This paper takes this research forward by using linguistic variables and triangular fuzzy numbers to model the decision maker’s (DM) risk and confidence attitudes in order to define a more complete MCDM solution. To illustrate the computation process and demonstrate ...

Sound decision-making processes for investments in water supply systems need to be developed. This need arises from the problem observed in developing countries of a growing demand for water supply projects coupled with a lack of financial resources available to invest in them. A second problem is the selection of a locality that is most in need of assistance for the implementation of the water...

Let us consider a finite set of alternatives A = {a, b, c, . . .} and a finite set of criteria N = {1, . . . , n} in a multicriteria decision making problem. Each alternative a ∈ A is associated with a profile xa = (x1, . . . , x a n) ∈ IR, where, for any i ∈ N , xi represents the partial score of a related to criterion i. We assume that all the partial scores are defined according to the same ...
