    "Program repair techniques attempt to fix programs by looking for patches within a search space of fix candidates. These techniques require a specification of the program to be repaired, used as an acceptance criterion for fix candidates, that often also plays an important role in guiding some search processes. Most tools use tests as specifications, which constitutes a risk, since the incompleteness of tests as specifications may lead one to obtain spurious repairs, that pass all tests but are in fact incorrect. This problem has been identified by various researchers, raising concerns about the validity of program fixes. More thorough studies have been proposed using different sets of tests for fix validation, and resorting to manual inspection, showing that while tools reduce their program fixing rate, they are still able to repair a significant number of cases. In this paper, we perform a different analysis of the suitability of tests as acceptance criteria for automated program fixes, by checking patches produced by automated repair tools using a bug-finding tool, as opposed to previous works that used tests or manual inspections. We develop a number of experiments in which faulty programs from a known benchmark are fed to the program repair tools GenProg, Angelix, AutoFix and Nopol, using test suites of varying quality and extension, including those accompanying the benchmark. We then check the produced patches against formal specifications using a bug-finding tool. Our results show that, in general, automated program repair tools are significantly more likely to accept a spurious program fix than producing an actual one, in the studied scenarios. "

    Mejora continua en un centro de atención al cliente
    (2011) Marchiori, Santiago Andrés; Galíndez, María del Carmen
    "A través de la aplicación flexible e integral del LEAN Six Sigma con el pensamiento sistémico y el Benchmarking, el proyecto busca superar inconvenientes de capacidad de trabajo en un centro de atención al cliente de una empresa de seguros. A la vez se estará alentando la utilización de herramientas que hoy en día están asociadas únicamente a grandes empresas para poder expandir su alcance a compañías con estructuras de PYMEs".
