electrifications, digitalization, onshore power supply applications, and energy storage and environmental friendliness, AGV-based automated container terminal (ACT) has become the development
However, as part of the conversion to Green Ports, Automated Guided Vehicles (AGV) have been and are being converted to battery-electric drives in many places. A special infrastructure is required for the energy supply. VAHLE has developed high-performance battery charging contacts for the efficient and safe energy supply of terminal vehicles.
This framework first models the AGV scheduling process as a Markov decision process (MDP). Furthermore, a novel scheduling algorithm called MDAS is proposed based on multi-agent deep deterministic policy gradient (MADDPG) to facilitate online real-time scheduling decision-making.

Lithium-ion battery-powered AGV is charging green energy at the charging station at CTA. Source: HHLA Hamburger Hafen und Logistik AG (HHLA), the leading European port and transport logistics group, has announced that it will use automated guided vehicles (AGVs) powered by lithium-ion batteries to move containers at its
At the end of 2023, CTA took the last diesel-powered AGV out of service. The fleet now consists of 100% battery-powered vehicles that run on green electricity. This means that fossil fuels are no longer required for all container transport from the ship to the container warehouse - the processes are fully electrified.
For automated container terminals, the effective integrated scheduling of different kinds of equipment such as quay cranes (QCs), automated guided vehicles (AGVs), and yard cranes (YCs) is of great significance in reducing energy consumption and achieving sustainable development. Aiming at the joint scheduling of AGVs and YCs with
This paper presents a safe A* algorithm for the path planning of automated guided vehicles (AGVs) operating in storage environments. Firstly, to overcome the problems of great collision risk and low search efficiency in the path produced by traditional A* algorithm, a new evaluation function is designed by introducing repulsive term and
To better utilize multi-load AGVs and enhance the sustainability of the logistics process, an energy-efficient path planning model is formulated for a multi-load
The cost of an automated guided vehicle depends on the type of vehicle, starting from $14.000 for an AGC, near $30.000 for a towing tractor, $60.000 for an automated pallet jack, around $80.000 for a forklift AGV and $150.000-$200.000 for an automated VNA. But there''s a bad news these numbers are just an indication.
