Very few industries can benefit more from maximizing supply chain efficiencies than the oil and gas companies. However, the behavior of such supply chains is too complex to be modeled analytically. Multi-agent systems show great similarity with respect to supply chains and provide the flexibility to model the complexities and dynamics of real world supply chains without excessive simplifying as...

The aim of any value chain & network analysis is to understand the systemic factors and conditions through which a value framework and its firms can achieve higher levels of performance. The upstream oil & gas business is increasingly stimulated for growth by federal legislation (e.g. tax credits unconventional gas plays), while the corporate earnings in the US midstream and downstream energy s...

Abstract: In this paper, we develop a novel electric power supply chain network model with fuel supply markets that captures both the economic network transactions in energy supply chains and the physical network transmission constraints in the electric power network. The theoretical derivation and analyses are done using the theory of variational inequalities. We then apply the model to a spec...

At present, throughout the world LNG investments are abounding. In particular, the US and the EU are trying to facilitate their security of natural gas supply. For this reason, LNG enables importers to extend their gas suppliers’ portfolio, considering that some producing countries can be reached only via sea transport. LNG will thus increase importers’ choice; at the same time it can widen the...

The present work proposes a computer-aided methodology for designing sustainable supply chains in terms of sustainability metrics by utilizing the P-graph framework. The methodology is an outcome of the collaboration between the Office of Research and Development (ORD) of the U.S. EPA and the research group led by the creators of the P-graph framework at the University of Pannonia. The integrat...

nowadays one of the most important energy sources is natural gas. by depletion of oil reservoirs in the world, natural gasâ will emerge as the future energy source for human life. one of the major concerns of gas suppliers is being able to supply this source of energy the entire year. this concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...

Past research has shown that firm announcements regarding their supply chains are not overlooked by the stock market. The stock market reacts positively to enhancements or negatively to disruptions in firm supply chains. Some have conjectured that the observed market reactions to announced enhancements or disruptions understate the importance of the firm‟s supply chain to the market value of th...
