Information Support Technology of Ship Survey Based on Case-based Reasoning
Abstract: Recently, the
significance of ship inspections hasbeen increasingly recognized because sea
pollution andsafety problems are occurring more and more frequently. However,
current ship inspections rely on the experience ofthe workers. Therefore, it is
difficult to understand, and hence to improve, the state of ship inspections.
The present problemsare that the ship inspection technical support level in
China is not balanced, especially as to the current situation with low level,
poor technologyin under-developed areas. In this paper, the case technology
about the case-based reasoning to the ship inspection is proposed. The methods
of normative inspection case representation are discussed.This is considered to
be the basis of case-based reasoning. Then the tertiary case structure with the
index is defined, in which the K-nearest neighbor method to calculate the
similarity between caseswas used so that the ship’s inspection information can
be searched effectively. In addition, animproved retrievalstrategy of the
nearest neighbor method is introduced. Therefore, in the inspection site,the
inspectors can acquire support information by the case bases, and then the new
cases are calculated automatically. Further, a ship inspection case
managementwereintroduced to improve the stability of the system. By carrying
the case-based reasoning into an inspection, an inspector can generate fault
information and inspection information simply and easily. Some examples of the
organization and retrieval are shown at the end of the paper.
