Assessment of energy supply security using an analytic hierarchy process based approach

Abstract

In this paper, we are interested in analyzing the energy supply security using one or several indicators to measure the extent of the energy security for different countries. Given that each parameter can’t give a clear idea about the energy supply risks, a composite indicator must be developped to summarize the information, to benchmark the countries and to monitor the efforts made to improve the security of supply. At this regard, based on analytic hierarchy process (AHP) method, we determine first the weight of a three considred parameters which reflect the supply situation in a general way. Then, we proposed a new linear composite indicator that mesures energy supply security taking into consideration the above-mentioned parameters. Afterwards, in order to verify the representativeness of this index, we calculate the new indicator for five energy supply situations and we test its sensitivity to each component.
