Combining a fuzzy inference system with an A* algorithm for the automated generation of roadmaps for Automated Guided Vehicles

Abstract: This paper proposes a method for the automated generation of roadmaps for AGVs. So far the roadmaps are mostly generated manually, which leads to long and laborious planning phases. The presented method incorporates both mathematical roadmap algorithms as well as human knowledge in the form of a fuzzy inference system. The results of the expert system are evaluated in comparisons to the A* algorithm and to manually generated roadmaps on a real production layout. In both cases the expert system performs better.

“…The A* algorithm was first proposed in 1968 by Hart et al [14], it is a heuristic search algorithm proposed by combining the advantages of the bestfirst search algorithm and Dijkstra's algorithm [37], [42]. The A* algorithm uses heuristic information to guide the search direction, which has been widely used to find the optimal solution in a short time, and has strong expansibility and adaptability to different scenarios.…”

“…However, existing approaches that prioritize maximizing redundancy can generate numerous unnecessary paths, resulting in low road utilization. The computation time, although not explicitly mentioned in any of the works, is also assumed to be relatively high [16]. Furthermore, introducing potential improvements by the experts can be difficult as the developed system is hard to understand.…”

“…These drawbacks have been addressed to some extent by [16], who combined advantages of mathematical optimization with human expertise using fuzzy logic. The proposed expert system enables automated generation of roadmaps that are not only mathematically efficient, but also applicable to real production systems.…”
