摘要: 针对具有多台自动导向小车的物料运输系统,需重点考虑其可跨多层且路径随机的特性。首先,根据自动小车可能的驻留点、运输路径和任务类型分解出多种不同的场景,计算其发生的概率;其次,采用两矩法描述节点的服务时间和分布类型,提出混合排队网模型分析系统的各项性能指标,并通过迭代算法进行近似求解;最后,设计集有效性和准确性验证为一体的三维仿真实验平台,将不同方法的求解结果进行对比分析,其结论可为该类物流系统的设计人员提供关于资源配置和路径规划等方面的优化建议。

Abstract: For a material handling system with multiple automated guided vehicles, its characteristics of multi-layer and random paths should be emphasized. Firstly, multiple scenarios are defined and their probabilities are calculated according to the possible dwell points, transportation paths and task types of automated guided vehicles. Secondly, the service time and distribution types of task nodes are described by the two-moment approximation method, and a hybrid queuing network model is proposed to analyze multiple system performance indicators, which is approximately solved by an iterative algorithm. Finally, a 3D simulation experimental platform is designed to verify the effectiveness and accuracy of the proposed method. Comparing and analyzing the solution results obtained by different methods, the conclusion can provide optimization suggestions in terms of resource allocation and path planning for designers of such logistics systems.
