Fuzzy comprehensive evaluation of emergency capability of port coal storage base with G1 method

Port coal storage base has strategic significance in China's energy; once an accident occurs, the level of emergency capacity is very important. Therefore, in this paper, the fuzzy comprehensive evaluation method based on the G1 method is proposed for emergency capability assessment. Firstly, the Delphi method is used to establish the index system of emergency capability assessment. To determine the index weight, the G1 method, a kind of method where it is needless to test its consistence, is adopted to calculate the weight of each index. The fuzzy comprehensive evaluation model for the emergency capability assessment is then made. Finally, the feasibility and effectiveness of the method are illustrated using an example. Results show that the method provides a new perspective and tool for emergency capability assessment.
