The safe operation of ro-ro passenger transport has become the focus of attention in recent years, and reasonable ship stowage is the basic guarantee for the safe navigation of ro-ro passenger ships. In view of the vehicle stowage problem, the Intelligent Stowage Expert Decision-Making System for Ro-Ro Passenger Ships is proposed. Based on the real-time loading situation of the ship and combined with the ship attitude monitoring information, the expert decision-making system analyzes the balance status of the hull and guides the dynamic stowage of vehicles. It aims to achieve scientific stowage of ro-ro passenger ships through the decision-making system and obtain a reasonable stowage plan, thereby improving ship stowage efficiency and transportation safety.
