A SAFE CHOICE PROCEDURE IN INTERACTIVE PROGRAMMING

In this paper we consider a multiple criteria decision problem framed as a vector optimization program (vop). Within this framework we propose an approach to problem resolution which allows for the selection of a compromise decision. This decision is sought by a decision maker (DM) through an iterative process, with subsequent proposals of the decision in question generated at different stages of this process. At each stage, a DM is asked to compare the decision being considered with the worst compromise, represented by the least acceptable levels of performance, and to express his opinion about the compared outcomes. This information is later used to generate a new decision, and the process is repeated. Following changes in a DM’S preferences the worst compromise is subsequently displaced.
