  • Analytical models for mean estimations of travel time and energy consumption per transaction in a shuttle based storage and retrieval system [Elektronski vir]
    Ekren, Banu Y. ...
    The aim of this study is to present analytical models for mean (expected value) calculations for travel time of shuttles and lifts per transaction as well as mean energy consumption calculations per ... transaction in a shuttle - based storage and retrieval system (SBS/RS) . Recent advances in automation technology has created a high variety of warehouse automation technologies one of which is SBS/RS (Lerher et al. 2013; Lerher et al., 2015a - 2015b). The high variety of warehouse automation results with the confusion of warehouse managers on identifying the right technology for their companies. Therefore, development of analytical models producing several performance measures from the system is critical to evaluate the system's performance promptly. By the analytical models provided in this study, system's performance can be evaluated promptly by changing the input parameters (e.g. discrete travel lengths, velocity of vehicles, acceleration/deceleration of vehicles, number of tiers, metrics, etc.) affecting the performance of the systems. The methodology illustrated in this paper can also be utilized in any systems having straight and discrete travel pattern with equal distance stop points (e.g. in subway system' s train travel estimations, etc.). I t is found that the proposed analytical results produce reasonable accurate results, typically less than 0.09%, when we compare them with the simulation results.
