Maritime navigation is an important mode of transportation in the country. With the development of the country and the world, there will inevitably be higher requirements for the safe transportation of ships in the future. Therefore, intelligent ships have become the latest research direction in ship design. And with the gradual development and improvement of big data and artificial intelligence technology in the industrial field, smart ships are an inevitable trend in the development of the shipbuilding industry. Smart ships need to maintain the stability of the ship to ensure the safety of the ship when operating at sea. Therefore, the research on the autonomous stowage of ballast water for smart ships in the future is very important. This paper analyzes the development background of intelligent ships, introduces the ship optimization model and optimization design algorithm, and speculates the future development direction of intelligent ships.
