system dynamics is a strategic approach for modeling complex systems and analyzing their behavior. dynamic behavior in entrepreneurial system can be modeled using system dynamics approach and dynamic hypotheses about the system`s behavior can be proposed and tested using simulation and computer aided tools. however, as the review of literature shows, studies which link system dynamics modeling ...

In this paper we discuss the scenario of Petroleum Engineering projects of Petrobras, a large Brazilian governmental oil & gas company. Based on this scenario, we define a set of requirements and system architecture to guide the construction of a Collaborative Engineering Environment for assisting the control and execution of large and complex in dustrial projects in oil industry, specifically ...

The present study was designed to evaluate the performance of alternative bio-based solvents, more especially 2-methyltetrahydrofuran, obtained from crop's byproducts for the substitution of petroleum solvents such as hexane in the extraction of fat and oils for food (edible oil) and non-food (bio fuel) applications. First a solvent selection as well as an evaluation of the performance was made...

Petroleum industry production systems are highly automatized. In this industry, all functions (e.g., planning, scheduling and maintenance) are automated and in order to remain competitive researchers attempt to design an adaptive control system which optimizes the process, but also able to adapt to rapidly evolving demands at a fixed cost. In this paper, we present a multi-agent approach for th...

Sunken marine power plants are one of the most dangerous types pollution. The reason for this is that various petroleum products settle at bottom sea and can remain there a long time, which causes irreparable harm to environment. Recently, problem decomposition in water has become particularly relevant. Oil its toxic components quickly destroy ecosystem, will entail dramatic consequences living...

The recent expansion in the production of shale petroleum crude oil, combined with the lack of new pipeline construction, has placed the railroads at the center stage for safe and efficient transport of very large volumes of this commodity. Petroleum crude oil poses fire risk in the event of train accidents. The consequence modeling based on the US DOT Emergency Response Guidebook (ERG) or ALOH...

The advancement in big data and artificial intelligence has enabled a novel exploration mode for the study of petroleum engineering. Unlike theory-based solution methods, data-driven intelligent approaches demonstrate superior flexibility, computational efficiency accuracy dealing with complex multi-scale, multi-physics problems. However, these models often disregard physical laws pursuit error...

 Taxation is one of the significant phenomena in any economy as it not only generates revenues for existing government, but also serves as a fiscal tool and stabilization policy. One of the main types of taxation is the petroleum tax which accounts for more than 30% of revenue for developed countries and more than 85% for developing economies. This work focuses on petroleum producing giants in ...
