Agentes que aprenden a establecer relaciones cliente-servidor en mercados bilaterales

En respuesta a presiones competitivas, pequeñas y medianas empresas han comenzado a formar redes colaborativas entre ellas. En este trabajo se presenta un modelo de compañía fractal basada en proyectos, en el cual los gestores de proyecto establecen relaciones del tipo cliente-servidor para negociar la asignación de un determinado recurso. Se propone la incorporación de algoritmos de aprendizaje por refuerzo a los gestores, de manera que puedan aprender a seleccionar a su socio más conveniente a lo largo del tiempo, y así maximizar sus beneficios.Trabajos de investigación.Sociedad Argentina de Informática e Investigación Operativa (SADIO

Las capacidades de los alumnos para el diseño de recursos tecnológicos a medida

Este trabajo sintetiza el estado de la investigación que justifica la metodología utilizada, describe las actividades más significativas y reporta los aportes concretos realizados por grupos de alumnos que fueron parte del proyecto. Así, un grupo se centró en la generación de aplicaciones tecnológicas propias para resolver problemas planteados por cátedras de matemática. Otro grupo se desempeñó como tutores para que el uso de los laboratorios sea un espacio de formación experimental. Se describen las acciones implementadas para la integración de contenidos y se realizan nuevos aportes para que las experiencias tengan continuidad, puedan ser replicables y útiles como prácticas profesionalizantes en ingeniería

Agent-based simulation of a project fractal company

In response to competitive pressures small and medium enterprises have begun to form alliances between them. This allows each company to increase their ability to react and adapt to changes in their business environment, concentrating on their core competencies, increase the availability of resources and gain economies of scale. Thus, the project-based fractal company model enables virtual and temporary integration between different companies to achieve specific business objectives. The successful implementation of the model lies in the establishment of client-server relationships between project managers. This paper analyses the use of agentbased simulation to show behaviors that emerge from the interaction of project managers and resources managers when they establish client-server relationships. To do this, use Netlogo language as a tool intends to demonstrate emergent behavior resulting from interactions between agents of the fractal company.XVII Workshop Agentes y Sistemas Inteligentes (WASI).Red de Universidades con Carreras en Informática (RedUNCI

Filtering Useless Data at the Source

There are some processing environments where an application reads remote sequential files with a large number of records only to use some of them. Examples of those environments are servers, proxies, firewall and intrusion detection log analysis tools, sensor log analysis, large scientific datasets processing, etc. To be processed, all file records must be transferred through the network, and all of them must be processed by the application. Some of the transferred records would be discarded immediately by the application because it has no interest in them, but they just consumed network bandwidth and operating system’s cache buffers. This article proposes to filter records from the source of data but without changing the application. Those records of interest will be transferred without modifications but only references to the other records will be transferred from the source to the consuming application. At the application side, the sequence of records is rebuilt, keeping the content of records of interest and filling the others with dummy values which will be discarded by the application. As the number and length of records are preserved (and therefore the file size too), it is not necessary to modify the application. Once a filtering rule is applied to a file, only the useful records and references to unuseful ones will be transferred to the application side reducing network usage, transfer time, and cache utilization. A modified (but compatible) version of NFS protocol was developed as a proof of concept.Red de Universidades con Carreras en Informátic

Diseño y simulación de un planificador para sistema de virtualización basado en Minix

El sistema operativo de microkernel Minix brinda un excelente entorno para incorporarle funciones de hipervisor. El presente trabajo busca diseñar y evaluar un planificador jerárquico que permita seleccionar en primera instancia la máquina virtual y luego el próximo proceso a ejecutar de esa máquina virtual. El proyecto propone un algoritmo de planificación de tipo token bucket (cubeta de fichas) para la selección de las máquinas virtuales y administración de los tiempos de CPU para cada una.Trabajo de cátedraSociedad Argentina de Informática e Investigación Operativa (SADIO
