“…The advantage of the method is apparent when the number of servers in the network is large. It has also been applied to several warehousing and manufacturing systems (Ekren et al 2014;Roy et al 2015;Kumawat and Roy 2021). Dhingra et al (2018) extend the method to solve a nonstationary SOQN based on a truck congestion problem in a container terminal.…”

“…Although AS/RS has been widely adopted for years, the research on its operational decision is still of great value, which can provide basic references for various warehouse technologies in smart warehouses. Today, AS/RS has evolved into an efficient system with many variants, including AVS/RS (Lerher et al, 2021), SBS/RS (Zhao et al, 2020a;Yetkin Ekren and Akpunar, 2021), compact AS/RS (Hao et al, 2015;Xu et al, 2018;Kumawat and Roy, 2021), and puzzle-based storage and retrieval system (Mirzaei et al, 2017;Yalcin et al, 2019). The system configuration of AS/RS and its variants can be affected by many factors, such as the configuration of rack (Yetkin Ekren, 2017), aisle (Roy et al, 2015a;Manzini et al, 2016), cross-aisle (Tutam and White, 2019a), space (Derhami et al, 2019), tier (Tappia et al, 2017), shape (Tappia et al, 2017;Tutam and White, 2019b), depot (Gharehgozli et al, 2017;Gharehgozli et al, 2021), shuttles (Ha and Chae, 2019), and pick position (Liu et al, 2021).…”

E-commerce, new retail, and other changes have highlighted the requirement of high efficiency and accuracy in the logistics service. As an important section in logistics and supply chain management, warehouses need to respond positively to the increasing requirement. The “smart warehouse” system, which is equipped with emerging warehousing technologies, is increasingly attracting the attention of industry and technology giants as an efficient solution for the future of warehouse development. This study provides a holistic view of operations management problems within the context of smart warehouses. We provide a framework to review smart warehouse operations management based on the characteristics of smart warehouses, including the perspectives of information interconnection, equipment automation, process integration, and environmental sustainability. A comprehensive review of relevant literature is then carried out based on the framework with four perspectives. This study could provide future research directions on smart warehouses for academia and industry practitioners.

“…Eder overcame this assumption in their recent studies [15,21,22] by modeling the SBS/RS with a continuous open queuing system with limited capacity. Recently, Kumawat and Roy [23] illustrated an original method for solving multistage SOQNs and validated it using a case study on a multitier shuttle-based compact storage system. Finally, they demonstrated the model accuracy by benchmarking their results with an existing approach in the literature.…”

The autonomous vehicle storage and retrieval system (AVS/RS) significantly improves the responsiveness and throughput of the traditional automated storage and retrieval system (AS/RS) in regard to handling unit loads. The AVS/RS consists of multiple tiers connected to an elevator system and is equipped with at least two autonomous vehicles, that is, a shuttle and satellite. Other necessary equipment are the lifts and input/output buffer areas. This paper aims to present and apply an original hybrid analytical-simulative model for the design of a deep-lane and multisatellite AVS-RS by evaluating and controlling the system performance. This AVS-RS is equipped with multiple free and non-free satellites for each tier. As an original contribution, this study reviews the literature on AVS/RS according to the introduction of multiple features categorized into five homogeneous groups: (1) rack configuration, (2) vehicle kinematics and configuration, (3) dispatching rules, (4) modeling approach, and (5) validation. Two of the most critical issues in existing research studies are the random arrival time of storage and retrieval transactions and the random storage policy. The proposed modeling approach is data-driven and based on realistic assumptions, filling the gap between the literature and real applications. This hybrid model is applied to a case study of the beverage industry according to a what-if comparative and competitive multiscenario analysis. This data-driven assessment supports the decision-making process on the number of satellites for each tier, while simultaneously controlling the service and waiting times, system throughput, and vehicle utilization. The analysis based on the maximum system throughput estimation demonstrates that introducing more than two satellites does not increase the productivity of the system.
