在分析铁路集装箱平衡装箱影响因素的基础上,结合货物装载稳定性、空间独占性与平衡性,以集装箱容积利用率最大为第一优化目标、载重量利用率最大为第二优化目标,构建铁路集装箱平衡装箱优化模型。引入邻度、层换差等概念,结合松弛策略和回溯策略,采用分层系列法,提出基于动态分层和定位规则的两阶段求解算法。实例结果表明,该算法能快速、有效求解铁路集装箱平衡装箱问题。
Based on the analysis of the influencing factors of railway container balance packing, taking the cargo loading stability, space exclusiveness and balance as the first optimization objective, the largest container volume utilization rate is the first optimization goal, the maximum utilization rate of load is the second optimization target, Railway container balance packing optimization model. The concept of neighbors and layers is introduced. By combining the relaxation strategy with the backtracking strategy, a hierarchical series method is proposed to propose a two-stage algorithm based on dynamic layering and location rules. The experimental results show that this algorithm can solve the problem of railway container balance packing quickly and effectively.
