Research on the Stowage Planning Model and Algorithms for Container Ships Considering Out-of-Gauge (OOG) Containers

This paper introduces an innovative optimization framework grounded in integer linear programming, meticulously examining pivotal factors encompassing container dimensions, varieties, weights, and destination ports. The model surpasses conventional approaches by meticulously orchestrating not just standard container stowage but also ensuring the judicious placement of specialized containers, notably out-of-gauge (OOG) units, thereby enhancing cargo security and transportation efficacy. By meticulously integrating multifaceted constraints-encompassing slot capacity thresholds, balanced weight distribution imperatives, and compatibility considerations among diverse container types—this model adeptly tackles intricate vessel stowage challenges. Experimental validations underscore its prowess in substantially elevating container loading ratios while concurrently safeguarding vessel stability. Consequently, it offers shipping enterprises a scientific and pragmatic decision-making tool, fostering operational excellence and competitive advantage.
