Abstract: The risk assessment of liquefied natural gas (LNG) transportation routes has raised researchers' concerns in recent years, which is a group multi-criteria decision-making (GMCDM) problems that involves experts' opinions from different fields. To improve the effectiveness in evaluating process, this paper proposes a risk assessment method to recognize the potential risks and selects the best LNG transportation route. Firstly, the authors construct the systematic risk evaluation indices, including four first-level indices (political, economic, transportation, and operation and management risks) and nine second-level indices. Then a novel risk assessment method of the LNG transportation route is developed, including opinion representation, consensus measurement and detection, personalized feedback, and selection process. Finally, a scenario analysis is provided to model the risk evaluation process and demonstrate the soundness and applicability of the presented model.
