Abstract

In view of the application requirements of large amphibious aircraft in maritime life accident rescue in middle and far seas and the insufficiency of research on dispatch decision, this paper constructed a large amphibious aircraft dispatch decision model based on an improved fuzzy algorithm. Based on the method of statistical analysis and expert discussion, this paper established a decision index system of large amphibious aircraft dispatch with 8 indicators with applicability, safety and reachability as the evaluation criteria. This paper got the decision indicator’s interval intuitionistic fuzzy number by constructing five grades fuzzy evaluation criteria and the membership functions of the indicators. This method reduces the subjective influence of determining the fuzzy number for each indicator solely by the expert score, and improves the objective credibility and accuracy of the decision results. Proposed fuzzy entropy to calculate the weight of each indicator, matching function is used to get the matching degree of large amphibious aircraft for different accidents, make the dispatching decision of large amphibious aircraft in maritime life accident rescue is more scientific and reasonable. Finally, the large amphibious aircraft dispatch decision model proposed in this paper is verified by a practical case, and the calculation results are compared with those of the commonly used TOPSIS algorithm and projection algorithm. The results show that the model is reliable and effective.
