“…As skyscrapers get higher, reducing the number of shafts needed becomes more important because they eat up valuable interior space on every floor (Figure 5). Double-deck elevators are most useful for applications in very tall buildings, particularly for shuttle services [14,15] . However, the double-deck elevators suffer from some operational challenges.…”

Effective vertical mobility is a crucial element in the design and construction of tall buildings. This paper reviews recent “smart” developments in elevator technologies and analyzes how they affect the construction and operation of tall buildings. In an approachable and non-technical discourse, it maps out, arranges, and compiles complicated and dispersed information on various elements of elevator design. It discusses hardware-based machinery, such as AC and gearless motors, machine-room-less (MRL) elevators, regenerative drives, elevator ropes, and LED lighting, as well as software-based solutions, such as destination dispatching systems, people flow solutions, standby mode, and predictive maintenance applications. Future vertical transportation models are also discussed, including multi-directional elevators, and circulating multi-car elevators. Lastly, the paper suggests fruitful avenues for further studies on the subject, such as robotics, 3D printing, and the impact of COVID-19 pandemic on elevator design.

“…Equal floor rise could present a limitation; i.e., for local service, double-deck elevators must load and unload two decks simultaneously. Even though traffic is reduced during off-peak hours, both decks will be operating [15,16] .…”

“…The scheduling algorithm has a wide range of applications, not only in elevators but also in computer hard disk, transportation, express transportation, and wireless networks [1][2][3]. The current common elevator scheduling algorithms include FCFS (First Come First Serve), SCAN, LOOk algorithm, SSTF (Shortest Seek Time First), SATF (Shortest Access Time First), etc., [4][5][6][7].…”

“…At the first iteration, the elevator is ready to go up and handle the reservation tasks on the first floor, and the initial value of the iterative algorithm satisfies the following relationship: The remaining matrix R (1) =W (1) up , the waiting matrix W As long as the users are not overloaded, the first floor users will be allowed to continue enter.…”

Elevators are an essential indoor transportation tool in high-rise buildings. The world is advocating the design concept of safety, energy-saving, and intelligence. We focus on improving operation speed and utilization efficiency of the elevator group. This paper proposed a real-time reservation elevator groups optimization algorithm, and a dynamic matrix iterative model has been established. The indoor navigation technology UWB is applied, which can help users to quickly find elevators. The manned equilibrium efficiency and running time equilibrium efficiency of elevator group are given. Moreover, the data filtering criterion formulas for user waiting time and elevator remaining space are defined. In this paper, three numerical examples are given. Example 1 is a single elevator in n-storey building. Example 2 is compared with different scheduling algorithms, such as FCFS, SSTF, LOOK, and SCAN algorithms, and the results show that our method has the advantages of short total running time and less round-trip frequency. At last, the matrix of numerical iteration results are visualized, and the data movement status of people on each floor can be observed. Example 3 introduced elevator group algorithms. For high-rise buildings, this paper adopts a high, medium, and low hierarchical management model; this model has high coordination, as well as fast response, batch process, and adaptive function. Finally, we also discussed and compared the complexity of single elevator and elevator group algorithms. Therefore, this method has great development potential and practical application value, which deserves further study.
