Abstract

This study delves into the problem of path planning for Automated Guided Vehicles (AGVs) in the electrode sheet production plant environment. Firstly, leveraging the grid method, a workshop environment model is constructed. An enhanced A* algorithm is devised, introducing a turning cost and a variable coefficient, effectively addressing issues of excessive path inflection points and lengthy computation times when dealing with large-scale environmental maps.For dynamic conflicts and deadlock issues within the local road network, two algorithms are introduced: the Dynamic Detection Algorithm based on Segment Reservation Policy (DD-SRP) and the Deadlock Resolution Algorithm based on Breadth-First Search (DR-BFS). A simulation experiment is designed and conducted. The experimental results underscore the superiority of the enhanced A* algorithm in terms of solution time and outcomes. Moreover, the proposed dynamic conflict and deadlock detection and resolution methods effectively achieve dynamic detection and deadlock resolution.

Keywords: Automated Guided Vehicle; Improved A* Algorithm; Routing Problem; Deadlock; Electrode Sheet Workshop.
