Determinación probabilística de la duración de un proyecto de construcción de una planta industrial mediante el pert y el cpm.

Abstract

Operations research is a tool with a scientific approach whose application improves decision-making when carrying out projects. Currently it is essential to get the most out of resources, this can translate into companies needing to be efficient especially with the time factor, for which PERT and CPM are used. In this investigation it was identified as problematic how the PERT and the CPM affect the completion time of the construction of an industrial plant in Puerto Bolívar; In order to solve this problem, the objective was to determine the probability of compliance with the request for the construction of an industrial plant in Puerto Bolívar in 44 weeks. Through a descriptive methodology and using the technique of documentary review, an application exercise could be solved in six stages. PERT and CPM are related and allow a graphical interpretation of a sequence of activities, identify where there can be no delays, quantify the total completion time of a project and forecast the probability of success in cases where you work with two times, maximum and minimums, through the normal distribution table. In conclusion, the project can be completed in 44 weeks with a very high probability of success.
