Application of Improved D-S Algorithm of Conflict Evidence to Capacity Evaluation
Journal Title: 河南科技大学学报（自然科学版） - Year 2018, Vol 39, Issue 5
Abstract
In order to accurately assess the capacity of the airport, considering the completeness of D-S evidence theory in the evidence confilt during the assessment, a new evidence combination method was proposed and introduced into dynamic capacity assessment.The D-S evidence theory fusion rules was not changed in the method and the concept of evidence reliability was introduced.Based on compatibility and exclusion, the evidence was divided into trusted part and unreliable part, and finally D-S evidence theory was used to fuse the data.Based on the D-S improvement algorithm, the dynamic capacity prediction model of the airport was established, and the model was applied to the dynamic capacity prediction process of an airport in China.The experimental result shows that the method can effectively deal with conflict evidence, reduce the subjectivity of assessment and the risk of air traffic management decisions.The optimized credibility is increased by 0.166 9.
