Title:
METHOD FOR CONSTRUCTING EVALUATION INDEX SYSTEM FOR AUTONOMOUS BERTHING AND UNBERTHING FUNCTION OF SHIP
Document Type and Number:
WIPO Patent Application WO/2024/077850
Kind Code:
A1
Abstract:
A method for constructing an evaluation index system for an autonomous berthing and unberthing function of a ship. The method comprises: dividing an autonomous berthing and unberthing process of a ship on the basis of a work flow, and taking each divided stage as a first-level index of an evaluation index system (101); preliminarily selecting second-level indexes under each first-level index according to the divided autonomous berthing and unberthing process (102); by using a statistical method, screening the second-level indexes on the basis of independence (103); by using an entropy weight method, determining the importance of the indexes on the basis of the significance of an information amount and according to the magnitude of an information entropy of each second-level index (104); and refining the evaluation index system, determining whether each second-level index can be further refined, and if so, continuing the division to generate third-level indexes (105). A method for constructing an evaluation index system for an autonomous berthing and unberthing function of an intelligent ship is provided, and by means of the method, corresponding evaluation index systems for different ship tonnages and carried devices can be constructed, such that the systems are applicable to various types of intelligent ships, and the subjectivity and randomness of manual screening for evaluation indexes are reduced.
