摘　　要：跨巷道多层穿梭车仓储系统集存储和分拣功能于一体,充分利用仓库立体空间,利用高层货架实现货物的密集存储,采用"货到人"订单拣选模式,能够快速响应订单,缩短分拣时效。跨巷道多层穿梭车仓储系统的性能评估包括:存储容量,拣选效率(即分拣系统每小时的订单拣选量),拣选时间(即订单从流入系统到分拣完成所用时间)。通过对系统拣选任务流程的分析,提出了单任务周期下系统分拣效率和订单拣选时间的有效评估方法,在此基础上提出跨巷道多层穿梭车仓储系统综合设计框架,通过分析系统配置优化模型,提出进化算法,求解系统最优配置,使其在满足系统性能要求的前提下成本最低,该设计框架精确的求解系统设施的最优配置,降低规划设计人员的工作强度。Cross-aisles multi-shuttle warehouse system has not only storage function but also the sorting function, and makes full use of warehouse space to achieve high-density storage by using high shelves. It uses "part-to-picker" order picking mode to respond quickly to orders and shorten sorting time. The performance estimation of cross-aisles multi-shuttle warehouse system includes storage capacity, throughput of system, and transaction cycle time. An effective method is proposed to estimate the system throughput and order transaction cycle time only considering single retrieval command, based on this, an integrated design framework for storage system of multi-lane shuttle vehicles across roadways is proposed. By analyzing the optimization model of system configuration, a evolutionary algorithm is proposed and the optimal configuration of the system is solved so that the cost is the lowest under the premise of meeting the system performance requirements. The framework solves the optimal configuration of the system configuration accurately and reduces the work intensity of the system designers.
