摘要： 根据多载具自动化存取系统的作业特点，考虑先到先服务和最近邻点两种作业调度规则，推导出多载具自动化存取系统行程时间期望值的解析模型。模型适用于不同载具数量和不同货架形状因子情形下系统吞吐量指标评价。采用蒙特卡洛数值模拟方法对模型进行验证。数值实验结果表明模型具有较好的精确度，为统一评价多载具自动化存取系统吞吐量绩效提供了有效工具。

Abstract: The automated storage and retrieval system (AS/RS) with multiple shuttles are addressed in this paper. It is assumed that the system operates under the first-come-first-served and nearest neighbor scheduling rules. According to the operational characteristics of the system, analytical models for expected travel time estimation are derived. These models are applicable for evaluating throughput of multi-shuttle AS/RS for circumstance with different number of shuttles and different types of shelves. The proposed method is validated by the Monte Carlo simulation. Results show that the proposed models are effective and accurate for evaluating the throughput of multi-shuttle AS/RS.
