摘 要: 提前拣选、压缩合流的分拣策略使双拣货区自动分拣系统的拣选效率明显高于单拣货区自动分拣系统,基于此提出该策略下品项分配优化问题。介绍压缩合流的工作原理,确定双拣货区的品项分配对订单的压缩程度及提前拣选时间的影响。以负的各订单提前拣选时间之和最小为目标函数建立数学模型,该模型可归结为0-1规划问题并应用最大最小蚂蚁系统算法求解。实例仿真与分析证明了该算法的有效性。 The strategy of parallel picking and compressible order accumulation makes the automated sortation system with double picking zones have a picking efficiency much higher than that with single picking zone. Based on this, the item assignment optimization problem is presented for this strategy. The principle of the strategy is introduced, which implies that the item assignment in two picking zones affects the performance of order compression and pre-picking time. A math model for this problem is established. ...
