Abstract:

The goal of this thesis is to automate recommendations to the Officer of the Deck when decisions are made concerning situations that involve risk of collision. A rule based expert system is designed and implemented as a solution to this task. The rules are based on regulations in the U.S. Coast Guard manual, Navigation Rules International-Inland. The expert system receives facts that describe the current situation, then searches the rule base for matching rules. The searching method is a hybrid form of forward chaining that searches cyclically through the rule base until all matches, intermediate and final, are located. The conclusions of the matching rules are displayed as a recommendation to the system user. The resulting system provides a valuable input to the Officer of the Deck, serving to increase the speed and reliability of the final decision by removing the necessity of manually looking up regulations or relying on memorization.
