Logistical model to approximate the S Curve of the planning of sewage projects
The engineering projects have a plan of activities to be carried out in an estimated initial time, which is contrasted with the real time that the execution of the project took. This initial plan is of utmost importance for both the builder and the contracting entity of the work, since this represen...

Este plan inicial es de suma importancia tanto para el constructor como para la entidad contratante de la obra, ya que representa una relación directa de los costos de cada etapa y el tiempo que demandan. La representación gráfica de esta relación se adopta como un recurso de planificación, y su forma es similar a la curva S, sobre este gráfico se aprecia que al inicio del proyecto los costos acumulados son crecientes, y al final del se observa que decrecen. Por tales razones, en este trabajo se presenta un modelo de ecuación logística con la que se predice la planificación de un proyecto de construcción de alcantarillado partiendo de un presupuesto dado para su ejecución y el tiempo inicial estimado. El modelo se construye a partir de una muestra representativa de proyectos de alcantarillado ejecutados en la provincia de Pichincha, y se valida empleando otros no tomados en cuenta en dicha muestra. El modelo que se propone en este trabajo, tiene como valor agregado su utilidad en la toma de decisiones por parte de los entes públicos, porque proporciona una estimación más precisa sobre el cronograma valorado del proyecto Universidad Centroccidental Lisandro Alvarado - Decanato de Ingeniería Civil 2019-07-31 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo científico de investigación original application/pdf https://revistas.uclave.org/index.php/gt/article/view/2281 10.13140/RG.2.2.22509.33769 Gaceta Técnica; Vol. 20 No. 2 (2019): July-December; 35-50 Gaceta Técnica; Vol. 20 Núm. 2 (2019): Julio-Diciembre; 35-50 Gaceta Técnica; v. 20 n. 2 (2019): July-December; 35-50 2477-9539 spa https://revistas.uclave.org/index.php/gt/article/view/2281/1292 https://revistas.uclave.org/index.php/gt/article/view/2281/1301 https://revistas.uclave.org/index.php/gt/article/view/2281/1323 |

The engineering projects have a plan of activities to be carried out in an estimated initial time, which is contrasted with the real time that the execution of the project took. This initial plan is of utmost importance for both the builder and the contracting entity of the work, since this represents a direct relationship of the costs of each stage and the time they demand. The graphic representation of this relationship is adopted as a planning resource, and its form is similar to the S curve. On this graph, it can be seen that at the beginning of the project the accumulated costs are increasing, and at the end of the project it is observed that they decrease. For these reasons, this paper presents a logistic equation model that predicts the planning of a sewer construction project based on a given budget for its execution and the estimated initial time. The model is constructed from a representative sample of sewerage projects executed in the province of Pichincha, and is validated using other that not taken into account in said sample. The model proposed in this paper has as an added value its usefulness in decision-making by public entities because it provides a more accurate estimate of the project's valued timeline |
