摘要
以料箱式自动立库为研究对象,考虑堆垛机实际作业中存在的加减速过程,以能耗、平均吞吐时间和成本的计算模型为目标函数,以货架数量、货格数量和堆垛机的运行参数为决策变量,建立自动立库存储区多目标优化模型.采用2种方法求解该多目标的混合整数非线性规划模型问题:使用经典遗传算法进行求解,得到不同权重下的解集;使用非支配排序遗传算法求取pareto解,得到非劣解的解集.这些解集是优化后决策变量的集合,根据这些参数组合可以确定存储区的大小,并辅助货架与堆垛机的选购.依据该模型的优化结果,可以设计出规划更合理的自动立库存储区,可为节能自动立库的建造提供有效参考.
A multi-objective optimization model studying storage area in mini-load AS/RS(automated storage and retrieval system)was raised.Take mini-load AS/RS as the research object,calculation models of energy consumption,average throughput time and cost of mini-load AS/RS as objective functions,and number of channels,number of storage compartment and operating parameters of the S/R(storage and retrieval)machine as the decision variables.Two methods were applied to solve the multi-objective mixed integer nonlinear programming model problem.One method used the classical genetic algorithm to get the solution set under different weights.Another method used non-dominated sorting genetic algorithm to obtain the pareto solution set.The solution set was the collection of optimized parameters,which determined the dimensions of storage system and helped to choose shelves and S/R machines.According to the optimal results of the model,storage area in AS/RS can be designed,which can provide reference for the construction of energy-saving AS/RS.
