摘要
提出了一种整数规划模型,用于自动化立体仓库中物料动态储位分配优化问题的建模,设计了一个两阶段的启发式算法,以求解初始解,利用禁忌搜索算法对初始解加以改进,并通过实例,对算法的效率和精度进行分析.结果表明,所提出的算法具有较好的鲁棒性和较高的求解效率,可以有效提高堆垛机的使用效率和仓库中的空间利用率.
An integer linear programming model was formulated to address the optimization problem of relocation in an automated storage/retrieval system.A two-stage heuristic method was developed to generate an initial solution.A tabu search algorithm was proposed to improve the solution.Experimental tests were conducted to evaluate the performance of the proposed optimization algorithm based on various data settings.The experimental results show the effectiveness and the robustness of the algorithm.The efficiency of the handling machine and the utilization of the warehouse are improved by applying the algorithm.
