Abstract: To improve the picking efficiency of Array automated picking device system,an items assignment method based on item correlations was proposed.Under the mode of serial order accumulation,the total order picking time of this system's orders was equal to the summation of working time in the zone.The model of items assignment model in array automated picking device was established by taking minimum summation of working time in the zone as the objective.To solve this model,a heuristic clustering algorithm was proposed based on similarity coefficient which expressed by saving single channel picking time due to deferent items parallelly picked.The main idea of this algorithm was assigned items with closer relationship into the same zone to increase the number of items parallelly picked in each zone and reduce the total number of zones participating in picking each order.Simulation experiments of array automated picking devices in the pharmaceuticals distributions centre showed that the algorithm could reduce the total order picking time by 8%.
