| The improvement of the quality, efficiency and reliability of the ship stowage is very important to assure the safety in marine transportation. Nowadays, much more work about the research and design of a ship stowage system focuses on stowage calculation by computer than on fully automatic stowage, and some ship stowage systems could make automatic stowage come true, but they only limit in such aspects of stowage as ship stability or trim. It is necessary to design a ship automatic stowage system for better efficiency. So, this paper takes the design of the bulk carrier automatic system as an example to search the key to the question of ship automatic stowage system.Based on the analysis of the stowage capability and its checking methods and the description of the ongoing research of Bulk Carrier Stowage System, the paper presents the designing scheme of Bulk Carrier Automatic Stowage System which utilizes the principle of expert system in artificial intelligence, and gets the results as follows:1. The paper presents the design methods of Knowledge Base and Decision Maker on bulk carrier stowage expert system. This method could also be used in other ship automatic stowage systems.2. The paper puts forward the concept of Efficiency Matrix. Its application in the bulk carrier automatic system solves the problem of adjusting cargo. This method is not only used in bulk carrier automatic system but also in other such automatic stowage systems as containers or general cargo ships.3. The paper programs a prototype system on Bulk Carrier Automatic Stowage System by Visual Basic 6.0 and Microsoft Access. The system could be used in maritime education and training, and even onboard ships with further improvement.Built with cleared structure, the knowledge base in the Bulk Carrier Automatic Stowage System with Expert System is conveniently expanded andmodified. And the system is easily maintained as a whole, so it is a productive attempt in designing Bulk Carrier Automatic Stowage System.
