摘　　要：为寻求散货船的最佳航次积载方案,在满足船体强度、稳性和吃水差约束的条件下,建立侧重于船体强度状况的散货船优化积载通用非线性数学模型.基于通用优化模型求解软件LINGO和散货船装载软件SEACOS给出一个完整的计算实例,验证数学模型.此项研究为各类船舶实现自动优化积载奠定理论基础,对提高各类货船运力、改善船舶耐波性、延长船舶寿命、确保船舶安全都具有实用价值.In order to seek the best voyage stowage plan for bulk carriers, a general nonlinear math model for optimal stowage of bulk carriers that focuses on hull strength is established to meet the hull strength constraint, stability constraint and trim constraint. Based on the optimization modeling software LINGO and the bulk carrier loading software SEACOS, a complete calculation example is put forward, and correctness of the math model is verified. The study provides a theoretical basis for the realization of automatic optimization of stowage for various types of bulk carriers, and is of practical value to increase transport capacity of various bulk carriers, improve sea-keeping performance of the ship, extend ship life span and ensure ship safety.
