Programación de proyectos aplicando lógica difusa y la teoría del valor ganado

A continuación os paso un artículo publicado en abierto sobre la programación de proyectos aplicando lógica difusa y la teoría del valor ganado. Espero que sea de vuestro interés.


This paper aims to present a comprehensive proposal for project scheduling and control by applying fuzzy earned value. It goes a step further than the existing literature: in the formulation of the fuzzy earned value we consider not only its duration, but also cost and production, and alternatives in the scheduling between the earliest and latest times. The mathematical model is implemented in a prototypical construction project with all the estimated values taken as fuzzy numbers. Our findings suggest that different possible schedules and the fuzzy arithmetic provide more objective results in uncertain environments than the traditional methodology. The proposed model allows for controlling the vagueness of the environment through the adjustment of the α-cut, adapting it to the specific circumstances of the project.

Abstract: Much of the efforts towards low carbon built environment focus on the building energy performance and the relationship between occupant behavior and efficient supply facilities, arguing that impacts are higher during operational stage. However little progression has been The ongoing study aims to provide a simplifed method to decide upon constructive systems for structural slabs based on hierarchical multicriteria weights applied to a set of criteria through a value function: durability, resource depletion, climate impact, investment cost, user comfort and functional design. The main function of slabs as load distribution layers of the structural frame used to be the solely priority of design practice. Other functions of the building as a dynamic system interact within the environment and occupants along time. Currently dealing with sustainable materials and life cycle inventories we aim to provide with a reproducible method for early election of the type of slab by embedding environmental (resource efficiency) and social (durability and performance) criteria among the design criteria. First, we seek for a way to hierarchically distribute the criteria and sub-criteria among the goals against resource depletion and the diverse alternatives. AHP-based MCDM is chosen to build a multi-level hierarchical structure of objectives, criteria, subcriteria, and alternatives. The analysis outlines the expert preferences for factors of buildability and cost premium of implementation of high environmental value of project design. Further analysis will focus on interrelation among factors.
