This document is about process automation. Production automation nowadays is related to
Automated Guided Vehicles (AVG). Former solutions applied fixed track solutions, which
provides cheap, centralized control, but human assistance is required, because this solution
cannot handle any anomaly. The other drawback of this solution is that any modification
of the system is expensive. The application of Automated Guided Vehicles (AVG)
in the production process, might eliminate the problems mentioned above. These Vehicles
can accommodate to the changing circumstances, even during a process modification.
Nevertheless, these Vehicles bring some new problems like source management or task management,
because these processes do not take place in system design unlike in case of fixed
track solutions. Avoiding collisions and controlling the Automated Guided Vehicles have
similar problems. MTA SZTAKI pays attention to these problems in its “Ipar 4.0” project.
This work is created during the related works of this project. This document focuses on
the problem of route planning. The topic of uptime of the AVGs is excluded, the main
topic is the route planning and collision avoiding. The main goal of my work is studying
available solutions, and specifying a new direction for further works for the solution of the
automating problems described above.
