Assessing energy security: An overview of commonly used methodologies

摘要: Abstract This paper provides an overview of methodologies used for quantitative evaluations security supply. The studied material is mainly based on peer-reviewed articles and the are classified according to which stage in supply chain their main focus directed to, as well scientific background. Our shows that a broad variety approaches used, but there still some important gaps, especially if aim study energy future-oriented way. First, need better understand how sources insecurity can develop over time they affected by development system. Second, current tendency each carrier separately needs be complemented comparisons different carrier's chains. Finally, static perspective system structure should with perspectives greater extent take systems' adaptive capacity transformability into account, factors potential reduce systems vulnerabilities. Furthermore, it may beneficial use methodological combinations, conduct more thorough sensitivity analysis alter mind-set from securing flows services.
