In order to improve the construction level of oil warehouse support capacity and scientifically evaluate the current development status of capacity, the fuzzy hierarchical evaluation method is applied to the evaluation of oil warehouse support capacity. Based on the analysis of the current situation, a support capability indicator system is constructed, and a model is established using the fuzzy hierarchical evaluation method. The evaluation is conducted by combining an example of an oil depot. The results indicate that the evaluation model can reflect the shortcomings and weaknesses of the construction of oil supply guarantee capacity, and has certain guiding significance for the construction of oil supply warehouse guarantee capacity.
