Opis:
In the paper an approach to decision making in situations with non-pointlike characterisation and subjective evaluation of the actions is considered. The decision situation is represented mathematically as fuzzy multiobjective linear programming (fMOLP) model, where we apply the reduced fuzzy matrices instead of fuzzy classical numbers. The fMOLP model with reduced parameters is decomposable into the set of point-like models and the point-like models enable effective construction of an optimisation procedure - fBIP, see Wojewnik (2006ab), extending the bireference procedure by Michalowski and Szapiro (1992). The approach is applied to a fuzzy optimization problem in the area of telecommunication services.

Opis:
In the perspective of parallel processing, a new sense of parametric optimization might be promoted. The paper shows that it, is possible to propose new parallel versions of basic optimization algorithms, as well as an advanced method of securing convergence in interactive mnltiobjective optimization and decision support, all based on a modified concept of parametric embedding. This general idea is exemplified for the case of the simplex algorithm of linear programming by a parameterized and coarse-grain parallel augmented simplex algorithm, where a linear optimization problem can be embedded into a multiple-ohjective family which introduces diversified directions of search cutting through the interior of the original admissible set. For the case of nonlinear programming, a parameterized and coarse-grain parallel variable metric pulsar algorithm is shortly presented, where parallel directional searches are combined with a parametrized variable metric to produce a pulsating, robust nonliear programming algorithm. These two examples concern very basic optimization tools ; at the other end of the spectrmn of optimization-related methods, a general method called outranking trials of securing convergence of interactive multiobjective optimization and decision suport is obtained through parameterizing an outranking relation and using basic properties of order-consistent achievement functions in reference point methodology for testing the existence of outranking points by parallel optimization runs. Thus, the paper presents the use of parallel processing to solve a wide range of modified parametric embedding problems related to optimization and decision support.

Opis:
We propose a methodology to support decisions on how to construct rankings of objects which account for decision makers' preferences. As it is not always so that objects to be ranked are known upfront, the methodology is focused on constructing ranking algorithms rather than rankings themselves. The methodology builds on Multiple Criteria Decision Making paradigms. To operationalize it we provide a consistent interactive framework which allows the decision maker to express his preferences with respect to objects directly, with respect to the criteria selection process (multiple criteria model building), and with respect to attributes resulting from the selected criteria. The methodology is illustrated by a numerical example of municipality rankings.

Opis:
Graphical analysis for interactive aid (GAIA) and the dominance-based rough set approach (DRSA) are compared as methods of explaining the solution to a multi-criteria ranking problem obtained using the preference ranking organization method for the enrichment of evaluations (PROMETHEE). The classification of 52 municipalities in Northern Quebec in terms of the socioeconomic situation is based on three attributes: home conditions, employment and demographic potential. The classification provided to the decision maker is aggregated information. To facilitate decision-making, the problem is first considered as a sorting task, in which municipalities are distributed into three categories: best (B), worst (W) or intermediate (I), based on the PROMETHEE ranking. In order to improve the position of a municipality thus categorized, the decision maker needs information that will answer the questions: What criteria are relevant to the municipality? What criteria are in conflict? What are the critical values of the criteria? We show that GAIA and DRSA provide convergent and complementary information that allow enrichment of the answers to these questions.
