Polar cruise ship fin stabilizer model selection method and device based on AHP-entropy weight method

The embodiment of the invention provides a polar cruise ship fin stabilizer model selection method and device based on an AHP-entropy weight method. The method comprises the steps: taking polar cruiseship fin stabilizer model selection evaluation as a target, taking a plurality of to-be-evaluated fins as an alternative scheme, and building a hierarchical structure model of polar cruise ship fin stabilizer evaluation; obtaining a weight vector of an objective index in the sub-criterion layer to the criterion layer through an entropy weight method; based on the hierarchical structure model, determining a weight vector of a subjective index of the sub-criterion layer to the criterion layer through an analytic hierarchy process; further, calculating a combined weight vector of the scheme layer to the target layer, and sorting the weight values of the alternative schemes to the target to finish fin stabilizer selection. According to the method, the analytic hierarchy process and the entropy weight method are combi
