[pt] METODOLOGIAS DE GERENCIAMENTO DE PROJETOS APLICADAS À RENOVAÇÃO DE LINHA FERROVIÁRIA / [en] PROJECT MANAGEMENT METHODOLOGIES APPLIED TO RAILWAY TRACK RENEWAL

RAMON FREITAS MENDES 07 October 2021 (has links)
[pt] Projetos de renovação ferroviária apresentam características de projetos complexos e repetitivos, dado seu grande número de recursos e fatores de influência e atividades repetitivas para determinadas unidades de produção. Neste contexto o presente trabalho buscou aplicar conceitos relativos a gerenciamento de projetos desse nicho e desenvolver uma forma integrada de trabalhar com a incerteza nesse ambiente. Foi aplicada a metodologia de planejamento de projetos chamada Linha de Balanço, utilizando informações do projeto em fase de concepção em uma empresa ferroviária. Em sequência foi desenvolvido um protocolo para obtenção da opinião de especialistas em informações críticas para o processo e obtidas as distribuições betas que melhor representam as informações elicitadas. A partir dessas entradas, foi desenvolvido um modelo de simulação das atividades do projeto para analisar o seu funcionamento em um ambiente virtual e livre de riscos e usar como ferramenta para aprimorar seu planejamento. Como resultados são apresentadas e analisadas as principais saídas do modelo e propostas formas de controle que possam auxiliar na retroalimentação do planejamento com informações do andamento do projeto após iniciado. / [en] Project Planning known as Line of Balance (LoB) was applied, using information from a project in the conception stage of a railway company. Next, a protocol was developed to obtain expert opinion on critical information for the process and beta distributions that best represent the elicited information. From these inputs, it was developed a simulation model of the project activities in order to analyze their operation in a virtual and risk-free environment and optimize their scheduling. As a result, the main outputs of the model are presented and analyzed, in addition with the suggestion of methods of control that can assist in the feedback of the planning process with status information of the ongoing project.

Evaluation and Comparison of Project Scheduling Methods and Software Used in the Construction Industry

Parlak, Mehmet 12 August 2016 (has links)
The objectives of this thesis are to evaluate scheduling methods and most common construction project management software (CPMS) which are Primavera and MS Project, and to determine most widely used project scheduling techniques and CPMS with a survey. The thesis focus on project scheduling since it is very deterministic for project success. Evaluation results indicate that, Gantt Chart Method and PDM are useful for small to medium projects, CPM is for complex projects, PERT is for uncertain projects, and LOB Technique is for repetitive projects. The comparison between Primavera and MS Project show that Primavera is more robust, professional, and detailed while MS Project is cheaper and easier. The survey was completed with 22 participants from construction companies in the US and Turkey and the results demonstrate CPM and Gantt Chart Method are the most common methods. Also, MS Project is the most widely used CPMS followed by the Primavera.
