Jet fuel supply chains are increasingly becoming agile. To build agile supply chains, jet fuel companies first need to have access to a large supply base and secondly need an efficient mechanism for supplier evaluation and selection. In this paper, we analysis the standard for evaluating jet fuel supplier and constructs an evaluation index system for jet fuel supplier evaluation in an agile supply chain. The index system consists of five primary indexes and fifteen secondary indexes. We also develop an evaluation method for jet fuel suppliers based on relational degree analysis and the method is demonstrated with an example.
