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.
