Productividad Automatizada Basada en el Itinerario Animado (APBSA): Una Simulacion Basada en un Enfoque del Analisis de Compensacion Tiempo-Costo
Publication: Journal of Construction Engineering and Management
Volume 140, Issue 4
Resumen
Muchos estudios de la productividad de los trabajadores de la construcción son realizados a un nivel macro. Dichos estudios intentan cuantificar la productividad o los cambios en la productividad de la industria completa o de un segmento de ésta. Este estudio está dirigido a estudiar la productividad a un nivel micro o de un proyecto. La herramienta desarrollada permite que una empresa pueda predecir, administrar e incluso optimizar la productividad asociada a un proyecto o a diferentes niveles de proyectos. El APBSA es una metodología dinámica de programación, que emplea datos de tendencias semanales de productividad laboral de la construcción en forma estocástica, con el fin de actualizar automáticamente la línea base de programación que fue creada al comienzo del proyecto por el administrador de la construcción. El APBSA informa las varianzas de la duración de las actividades de construcción y realiza animaciones del progreso del trabajo, con los datos más actuales disponibles, en un ambiente 4-D. Los contratistas pueden mejorar su planificación al emplear el APBSA junto con la Modelación de Información de Edificaciones (BIM), lo que les ayudará a optimizar la productividad de su trabajo. Como caso de estudio, se modeló una Instalación de Ingeniería de Sistemas, de tres pisos, en la Base de la Fuerza Aérea (ABF) de Hanscom. El modelo fue desarrollado con el propósito de demostrar los impactos sobre el programa de línea base de los indicadores de productividad estocásticos basado en tiempo y costo. Un análisis del balancetiempo-costo fue también realizado para mostrar los efectos de las varianzas de duración en el costo del proyecto.
