Multi-UUV task sea area importance clustering method based on grey system theory

The invention discloses a multi-UUV task sea area importance degree clustering method based on a grey system theory, and relates to a multi-UUV task sea area importance degree clustering method. The invention aims to solve the problems that efficiency and precision are difficult to consider in a conventional method, particularly for a sea area environment under the influence of uncertain factors, importance degrees of all areas may be different, and UUV resources are wasted and search efficiency is low due to the fact that task areas are averagely divided. The method comprises the following steps: step 1, meshing a task area based on UUV detection capability; 2, constructing an expandable task sea area importance degree evaluation index set; step 3, evaluating and clustering region importance based on a grey system theory; step 4, establishing a refined building strategy of a part of the region; and step 5, establishing a multi-UUV area cooperative patrol strategy. The invention belongs to the technical field
