Abstract-Managing the Performance Evaluation Process plays a leading role in ensuring efficient business entities. At the University of Information Sciences is performed through indicators established models that are reflected in the skills of workers. However, it is not possible to report on their behaviour, nor have techniques for help in making decisions on evaluations. This paper describes the solution to the problem from the computerization of the Performance Evaluation Process for which there was a coded Web application using PHP where an inference engine implemented using aggregation operators for information on the prioritization requirements to contribute to decision-making on the performance evaluation. Codelgniter Fremework was used as database manager PostgreSQL, Public Key Infrastructure to sign electronic documents. The system also provides a set of reports that provide management information to senior management, with agility, accuracy, reduces the cost of material and human resources. Resumen -La gestión en el proceso de evaluación del desempeño juega un papel importante para garantizar la eficiencia en las entidades laborares. En la Universidad de las Ciencias Informáticas se realiza a través de modelos con indicadores establecidos en los que son reflejadas las competencias de los trabajadores. Sin embargo, no es posible realizar informes sobre sus comportamientos, ni contar con técnicas de ayuda en la toma de decisiones para las evaluaciones. La presente investigación describe una solución a la problemática planteada a partir de la implementación de un motor de inferencia basado en operadores de agregación de la información como ayuda a la toma de decisiones sobre la evaluación del desempeño codificado mediante un sistema informático. El sistema propuesto brinda un conjunto de reportes que facilita la gestión de la información a los principales directivos, con agilidad y precisión y disminuye el gasto de recursos materiales y humanos. Se aplica un estudio de caso mediante el cual es posible determinar el índice de concordancia sobre las decisiones asumidas. Keywords-Aggregation of informationPalabras Claves-Agregación de la información; evaluación del desempeño; toma de decisiones; motor de inferencia; sistema informático.Abstract-Managing the Performance Evaluation Process plays a leading role in ensuring efficient laborares entities.
