Abstract

Purpose This paper aims to propose a simulation model integrated with an empirical regression analysis to provide a new mathematical formulation for automated storage and retrieval system (AS/RS) travel time estimation under class-based storage and different input/output (I/O) point vertical levels. Design/methodology/approach A simulation approach is adopted to compute the travel time under different warehouse scenarios. Simulation runs with several I/O point levels and multiple shape factor values. Findings The proposed model is extremely precise for both single command (SC) and dual command (DC) cycles and very well fitted for a reliable computation of travel times. Research limitations/implications The proposed mathematical formulation for estimating the AS/RS travel time advances widely applied methodologies existing in literature. As well as, it provides a practical implication by supporting faster and more accurate travel time computations for both SC and DC cycles. However, the regression analysis is conducted based on simulated data and can be refined by numerical values coming from real warehouses. Originality/value This work provides a new simulation model and a refined mathematical equation to estimate AS/RS travel time.

AS/R系统在不同输入输出点级别的类存储中的行程时间：一个新的公式

目的本文旨在提出一个与经验回归分析相结合的模拟模型，为基于类别的存储和不同输入/输出（I/O）点垂直水平下的自动存储和检索系统（AS/RS）行程时间估计提供一个新的数学公式。设计/方法/方法采用模拟方法计算不同仓库场景下的旅行时间。模拟使用多个I/O点级别和多个形状因子值运行。发现所提出的模型对于单指令（SC）和双指令（DC）循环都非常精确，并且非常适合可靠地计算行程时间。研究局限性/含义所提出的用于估计AS/RS旅行时间的数学公式推进了文献中广泛应用的方法。此外，它还支持SC和DC循环更快、更准确的行程时间计算，从而提供了实际意义。然而，回归分析是基于模拟数据进行的，可以通过来自真实仓库的数值进行细化。原创性/价值这项工作提供了一个新的模拟模型和一个精确的数学方程来估计AS/RS旅行时间。
