| 目的 为了提高单环单向循环搬运系统的搬运量和系统效率，在单环单向循环搬运系统中增加交叉环且优化交叉环的布局（设置位置及数量）可以避免小车间不必要的等待时间，为搬运系统提供捷径，且提高搬运效率。方法 构建系统的数学模型并对不同交叉环布局（设置位置及数量）进行理论分析，在2种基本调度算法下进行仿真实验优化。结果 通过理论和仿真实验分析得出，2种基本调度算法下，交叉环设置为布局1时的系统干涉情况最小，但系统单位时间搬运量较少；交叉环设置为布局4时系统单位时间搬运量最大，但系统干涉增加。结论 从减少能源消耗（干涉）的角度优化，交叉环应设置1条且设置在系统正中间位置，系统干涉时间最小，单位时间搬运量也最少；从单位时间搬运量最大的角度优化，应在每2个处理站点中间设置多条交叉环，单位时间搬运量最多，但系统干涉时间最大。 |

| To increase the throughput and improve the performance, adding shortcuts and optimizing the different amounts and locations of shortcuts layout in unidirectional circulation-type material handling system on a single loop can provide the shorter route and also improve the efficiency of the system. This paper made a mathematical model of this system, analyzed the different amounts and locations of short-cut layout and then made the simulation experiments under the condition of two basic scheduling rules. According to the analysis and experiment, under the condition of two basic scheduling rules, the first layout of shortcuts setting could decrease the interference of the system but lower the throughput. The fourth layout of shortcuts setting could maximize the throughput of the system but increase the interference. In conclusion, from the view point of decreasing the energy consumption (interference), when the only shortcut must be located in the middle of all the processing station, the interference time achieves the minimum while the throughput is the lowest. From the view point of increasing the throughput in the system, when all the shortcuts must be located in the middle of each two processing stations, the maximum throughput can be achieved while the interference time is increased. |
