IZAR - the Concept of Universal Multicriteria Decision Support System (original) (raw)
Many real decision making problems are evaluated by multiple criteria. To apply appropriate multicriteria methods it is necessary to have software support. The paper presents the universal multicriteria decision support system IZAR.

IZAR not only suggests the most suitable method, but it also applies it immediately to the problem being solved. By means of properly formulated questions the expert system selects the right procedure for solving the problem, taking into account its peculiarities regarding entries and additional information which can be assigned to the system by the user. An appropriate classification of multicriteria models and methods is needed because of universality of the system. The system solves discrete and continuous problems. Basic models for multiattribute evaluation and multiobjective optimization probl...
