摘　　要：为实现船舶节能增效的目标,在满足船舶浮态、稳性和纵强度要求下,提出一种空船优化压载状态的算法,建立空船压载状态多目标优化计算的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,通过一个完整计算实例验证算法和模型.此项研究表明,该方法可在确保船舶安全的前提下,减少船舶在空船压载航行时的水下阻力,改善船舶耐波性,延长船舶使用寿命,具有实用价值.To realize ship energy efficiency and meet the requirements of floating conditions, stability and hull strength, an algorithm and a general nonlinear mathematical model for multi-objective optimum bal- last conditions of light ships are proposed. Based on the general optimization modeling software LINGO and the loading software for bulk carriers SEACOS, a complete calculation example is given to verify the algorithm and model. The study shows that the method can decrease water resistance of light ships in bal- last conditions, improve seakeeping performance, and extend life span of ships, which is of practical sig- nificance.
