Método multicriterio cardinal de decisión en grupo con alternativas clasificadas por categorías

Abstract

This article studies the problem of making decisions with a multi-criteria approach, in groups whose members share objectives. These processes offer several advantages: collaborative learning, convergence of priorities and behaviors, higher level of commitment to agreed actions. On the other hand, these exercises require time and can be tedious when decisions are made systematically and with high frequency. There are also drawbacks to be overcome, because these processes can be affected by group pressure, which inhibits individual contributions and makes it difficult to build commitments, or by disturbances in the available information (imprecision, uncertainty or lack of some data). For this reason, the paper presents a method that structures the problem with subjective criteria and a set of categories that facilitate its evaluation. Priorities and preferences are represented by cardinal utilities. The proposal includes procedures aimed at reducing peer pressure, disruption and time required. The work includes an application to the treatment of nonconformities, in a productive process. Among the conclusions, the following stand out: the participants adopted the methodology without inconveniences and they were able to agree on the categories. In addition, they agreed that the proposal allows for a significant reduction in analysis times.
