Abstract

This paper introduces a Graph Convolutional Network (GCN)‑based ranking model to optimize drug placements within Automated Drug Dispensing Systems (ADDS). The method represents drugs as nodes with features derived from monthly consumption frequencies and connects them through a co‑use graph. The GCN uses message‑passing operations to learn representations that capture drug demand behavior and co‑prescription relationships, producing drug scoring values. These scores are then used to construct an optimized placement matrix that positions high‑priority drugs in the most accessible compartments of a manipulator‑arm‑based ADDS. The optimized placement configuration achieved a 27 % reduction in average retrieval times compared to random placement strategies. Additionally, t‑SNE analysis of drug embeddings revealed meaningful clusters that reflect drug relevancy. The approach is adaptable to different ADDS configurations and demonstrates potential for significant operational improvements in healthcare logistics.
