Research on Unmanned Vehicle Material Security Path Planning Model in Plateau Area

In a specific operational area, we aim to establish a comprehensive logistics support and transportation system linking "rear area - transit warehouse - forward area" utilizing unmanned ground vehicles (UGVs) of various models. Initially, following reconnaissance, candidate locations for the rear area, forward area, and transit warehouse were identified, along with three-dimensional terrain data of the operational zone, technical specifications of UGVs, and operational protocols. Subsequently, an indicator system for UGV logistics support path planning was constructed, primarily defining metrics for path safety, stability, and time efficiency. Combined with constraints such as power consumption, maximum traversable slope limitations, and movement regulations of UGVs, a multi-objective path planning evaluation model was established. Finally, an improved A* algorithm was employed to determine the optimal route. This model provides scientific reference for UGV support missions in plateau regions.
