In particular, we point out how some painting algorithms may help decision makers to understand problems subject to fuzziness based upon a graphical first approach, like Statistics use to do. Moreover, we point out that although the standard communication tool with machines are either data or words, we should also consider certain families of graphics for such a role, mainly for the output.engbook parthttp://www.gimac.uma.es/ipmu08/proceedings/papers/189-monteroetal.pdfopen access519.8Investigación operativa (Matemáticas)1207 Investigación Operativa
