Resumen
La adjudicación de un contrato por parte de una administración pública depende de criterios de adjudicación evaluables mediante fórmulas y de criterios evaluables mediante juicios de valor. Los primeros disponen de fórmulas definidas mientras que los segundos siempre tienen un sesgo subjetivo porque dependen del técnico que realiza la valoración. Con objeto de minimizar las consecuencias de las arbitrariedades o incertidumbres en la evaluación de los criterios evaluables mediante un juicio de valor se puede recurrir a la lógica difusa. La lógica difusa, borrosa o fuzzy es el razonamiento matemático que permite calcular de forma exacta las magnitudes correspondientes a conceptos vagos o situaciones poco previsibles para poder tener control sobre ellas. El objetivo del presente trabajo es desarrollar una metodología que permita a los órganos de contratación la evaluación de los criterios evaluables mediante un juicio de valor mediante la utilización de la lógica difusa.
Abstract
The award of a contract by a public administration depends on criteria assessed by formulae and criteria assessed by value judgements. For the former, various predetermined formulae can be employed while for the criteria assessed by value judgements will always contain some subjective bias by the individual who performs the evaluation. In order to minimize the consequences of the arbitrariness or uncertainties in the evaluation of criteria assessed by value judgments is possible to use the fuzzy logic. Diffuse, fuzzy or fuzzy logic is the mathematical reasoning that allows to calculate accurately the magnitudes corresponding to vague concepts or situations that are not very predictable to have control over them. The objective of this paper is to show a methodology which permits to the contracting authority to evaluate the criteria assessed by value judgments through fuzzy numbers.
