1. O problema de planejamento e agendamento de operações em uma rede de oleodutos / The problem of planning and scheduling the operation of an oil pipeline
Um conjunto de órgãos distribuidores de derivados de petróleo, incluindo refinarias e terminais, possuem demandas locais e produções de diferentes produtos ao longo de um dado horizonte de tempo. No entanto, pode não haver estoque local de algum produto para satisfazer a demanda correspondente, ou pode não haver espaço nos tanques para estocar uma pr

2. Modelos computacionais para o escalonamento de tarefas em redes de dutos / Computational models for task scheduling in pipeline networks
This dissertation deals with a very difficult overly-constrained scheduling challenge: how to operate a large pipeline network in order to adequately transport oil derivatives and biofuels from refineries to local markets. Pipeline network systems are considered the major option for transporting these product types, in view of their many economic and environ

3. Otimização da programação de curto prazo de duto bidirecional de derivados de petróleo. / Short-term scheduling optimization of derivative petroleum bidirectional pipeline.
Pipeline systems play a major role in the supply chain of the petroleum industry. These systems are responsible for the transportation of most of the crude oil and petroleum derivatives. Pipeline systems transfer large amounts of different petroleum types and their products at a lower cost than any other transportation mode. Pipelines interconnect oil fields

4. Optimization of pipeline scheduling operations: efficient formulations and hydraulic considerations. / Otimização da programação de operações dutoviárias: formulações eficientes e considerações hidraúlicas.
Pipeline systems correspond nowadays to the most efficient mode for the transportation of large amounts of liquid and vapor products for long distances. Pipelines are utilized by the Petroleum Industry to transport petroleum and its product derivatives. The present work addresses the scheduling of pipeline distribution of a system that operates with a pipeli

5. PLANEJADORES PARA TRANSPORTE EM POLIDUTOS / PIPELINE TRANSPORTATION PLANNERS
Pipelines have an important role in oil and its derivatives transportation, since they are the most effective way to transport high volumes through long distances. The motivation for this work is that a non negligible part of the final price for those products are due to transportation costs. Few authors have addressed this problem, with most of the previous

6. An milp formulation for the scheduling of multiproduct pipeline systems
Pipelines provide an economic mode of fluid transportation for petroleum systems, specially when large amounts of these products have to be pumped for large distances. The system discussed in this paper is composed of a petroleum refinery, a multiproduct pipeline connected to several depots and the corresponding consumer markets that receive large amounts of

7. Planning and scheduling for petroleum refineries using mathematical programming
The objective of this paper is the development and solution of nonlinear and mixed-integer (MIP) optimization models for real-world planning and scheduling problems in petroleum refineries. Firstly, we present a nonlinear planning model that represents a general refinery topology and allows implementation of nonlinear process models as well as blending relat
