Problem. As one of the three key elements of flexible manufacturing systems (FMS),
automated guided vehicles (AGVs) play a significant role in material handling systems. They've been
around for more than a decade, primarily in Europe. AGVs were formerly utilized mostly in
production lines, but due to recent industrial development, they now play a vital role in a variety of
different applications and domains, including warehouses, port facilities, transportation systems, and
even the medical sector. Goal. The purpose of the work is to analyze two methods of AGV control and
the paths that the AGV should follow during transport operations, taking into account safety and
limitations for heavy loads that need to be transported in difficult conditions. Methodology. We
attempted to provide a summary of the two existing AGV control methods, centralized and
decentralized control offered by major manufacturers in this study. Almost all function in a centralized
manner, with a single central controller controlling the whole fleet of AGVs. The author sees a
tendency toward decentralized systems in which AGVs make individual decisions in favor of
transportation flexibility, robustness, and adaptability. A brief explanation of well-known and mature
navigation technologies used by AGVs in the industry is also provided, along with both physical and
virtual paths to be followed by the AGV during transportation operations, since these technologies get
to be a key issue given the safety constraints, particularly for heavy loads to be transported in
challenging environments. Results. This paper covers one of the key tasks that must be completed in
order to control an AGV system for a central and decentral architecture, for which we have already
given a broad overview, as well as the differences between the architectures and their benefits and
drawbacks. Originality. The author sees that the merging of various techniques we have will lead to
more and new challenges as well as innovations, however, that practical application of distributed
control still requires further research and studies and has a way to go in terms of taking other sections
such as safety and sustainability into account. Practical value. The primary benefits and drawbacks of
various technologies are discussed, as well as how we might improve the efficiency of some of them.
