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

Résumé

In the emergency capability assessment of port coal storage base, one of the most important procedure is to determine the index weight. The AHP method has been widely applied at present, but when this method meet many factors or big problems, it’s easy to appear that the judgment matrix is difficult to meet the requirement of consistence and hard to further divide into groups. In this paper, G1 method, a kind of method needless to test its consistence, is adopted to calculate the index weight of each factor in evaluating emergency capability of port coal storage base. Then according to the index weight and point of each factor, get the result of the emergency capability level of base. Finally, according to the evaluation results put forward the improvement suggestion. Result shows that when the number of index is numerous, using the G1 method can reduce the amount of calculation obviously. And the G1 method is easy to operate.
