## 4 Future Studies and Conclusions  
In a previous study [84; 85], we proposed another proposal for an automated transportation system (ATS). The overhead areas in warehouses, factories, and hospitals are effectively utilized by this system to conserve floor space for product transportation purposes. The purpose of this implementation is to improve operational capacity and productivity. The system consists of mechanical, control, and sensor elements. Future research should focus on optimizing the control system to enhance efficiency and reduce time consumption in the freight forwarding domain. The topic of interest is the identification of cargo and the methods used for identifying purposes. To prevent collisions during the execution of multiple tasks simultaneously, the system should employ a mechanism to divide the concurrent movement of several vehicles. It should determine the correlation between the distance traversed and the quantity of vehicles needed, as it relates to the number of stations and available shuttles. Future studies also need to focus on identifying and analyzing suitable algorithms that could effectively contribute to energy conservation. The charging system is not functioning properly. A technological framework designed to regulate and optimize the use of electrical energy stored in batteries is known as the battery power management system. Furthermore, the Telelift system, as described, provides a high-rise conveying system that utilizes vehicles for the transportation of medications. The aim of this innovative approach is to address challenges related to staff shortages and the potential contamination of diseases. Future studies should focus on the utilization of secured, electronically monitored trucks and an interconnected network of tracks to improve the automated medication delivery process in Vietnam using queuing networks. Although the primary use of this system is in hospitals, it can be implemented in other multilevel institutions, factories, and so on. For instance, this system can be utilized in libraries to move books or in manufacturing operations to transport various items. Management systems, control algorithms, and algorithms for effectively controlling the simultaneous operation of various vehicles inside the system are the focus of ongoing research and development efforts. The modular mechanical design approach for stages, which includes straight movement, directional changes, and vertical transitions, has been developed to fit the specific context in Vietnam. The purpose of this system is to be installed in pre-existing spaces, with a focus on utilizing the vertical space available. The distinguishing characteristic of Vietnam's system is its ability to be deployed over various locations, necessitating the inclusion of mechanical, electrical, and control components. Furthermore, it has the unique ability to accommodate future expansion, which includes mechanical and electrical aspects, as well as control mechanisms. The significance of bin synchronization in parts-to-picker systems is highlighted in this research. This issue has not been well addressed by the scientific material handling community or warehouse practitioners for future studies in warehouse transportation, both in manufacturing and medicine transporting. The research provides system configurations that reduce the amount of effort needed for bin supply. Furthermore, it demonstrates that synchronization based on demand could be a viable alternative to traditional supply-oriented decision tasks. In future studies, it is crucial to prioritize empirical evaluation of setup durations and comprehend the impact of bin changes and setups on picking performance. Also, the methods for resolving uncertainties related to synchronization issues. The development of novel goal functions and enhanced modeling fidelity could be a result of this, particularly in the context of e-commerce warehouses. A comprehensive study is necessary in the field of warehousing.
