1. Introduction

In the era of rapid information development, supply chain management has become one of the key strategies for companies to enhance their competitiveness, especially for e-commerce enterprises [1]. With the increasing demand for orders, consumers' stringent standards for delivery, and the enormous operational costs, traditional supply chains can no longer meet today's market demands. Traditional supply chains suffer from low efficiency, insufficient operational agility, and high costs. Therefore, e-commerce companies are transitioning from traditional supply chain models to intelligent supply chain models to address market needs. Amazon, as a globally renowned e-commerce company, stands out in supply chain management. The company has employed numerous artificial intelligence technologies in its supply chain, such as demand forecasting, warehouse automation, intelligent algorithms, and drone delivery, all of which have improved operational efficiency and reduced supply chain costs [2].

This paper first introduces the background of Amazon e-commerce and the development process of supply chain, then analyzes how Amazon supply chain management uses AI and what contributions AI has made to supply chain, then conducts case analysis on AI, and finally discusses the challenges of intelligent supply chain management in Amazon and future development trends. This paper not only provides case studies on the integration of supply chains with AI but also offers important references for other e-commerce companies.

2. AI applications in Amazon’s supply chain management

Amazon has grown over the years into a global leader in commerce, expanding into cloud computing and artificial intelligence. The company has evolved from its early reliance on third-party delivery, through the development of Prime membership services and a global warehouse network, to the mature stage of automation technology and drone delivery, significantly enhancing operational efficiency[3].

2.1. Robotic learning algorithms and demand forecasting

Amazon’s robotics primarily rely on supervised learning, with some applications of reinforcement learning to optimize operations, while supervised learning applies XGBoost and LSTM for demand prediction [4-5].

First, the reinforcement learning system is composed of state space S, action space A, state transition function P, reward function R, and discount factor. Its goal is to learn an optimal strategy to achieve the maximum return. During the learning process, a precise model needs to be established. Amazon's robot reinforcement learning is typically applied to inventory management, logistics, and procurement. The shortest path in robot reinforcement learning saves time for each order, thereby improving the efficiency of Amazon's tens of thousands of daily orders. This not only reduces costs but also enhances customer satisfaction.

Secondly, supervised learning involves using known input data and corresponding expected output data, which are clearly defined and labeled, to train machine learning models. Algorithms in supervised learning include XGBoost, which combines regression analysis for precise prediction. LSTM is used to process time series data, learning sales trends. Typically, Amazon robots apply supervised learning to predict product sales, optimize inventory, manage sales activities, calculate the impact of different weather conditions on delivery times, forecast return rates, and predict market environments. For example, Amazon robots predict price movements and regularly update prices, maximizing their utilization. Secondly Amazon robots predict future sales based on the historical sales of each product, so that they can prepare accurate inventory in advance, so that inventory is optimized and storage costs are reduced. In addition Robots can predict delivery times for different weather conditions. This allows them to focus on deliveries during good weather and prepare adequately for deliveries in bad weather. They use different modes of transportation based on the weather, preparing goods in advance to save operational time costs. By predicting traffic flow and calculating traffic conditions on various roads at different times, they choose the shortest route for delivery [4].

2.2. Intelligent warehousing and automated delivery

In modern logistics management, the application of intelligent technology is particularly important.

Amazon has introduced Kiva robots, which can match the length, width, and height of goods to storage racks, maximizing storage space utilization while reducing human movement time and error rates. Moreover, AI algorithms enable the robots to calculate the shortest path for placing items, preventing collisions and saving time costs, thus enhancing logistics efficiency.

As technology continues to advance, drone delivery is gradually becoming a new trend. Amazon first launched an innovative last-mile drone delivery service in December 2022, utilizing artificial intelligence and remote control technologies to achieve drone delivery services. Artificial intelligence optimizes the delivery routes through machine learning, ensuring efficient delivery [6]. Computer vision and sensors enable drones to automatically avoid obstacles and accurately reach their destinations. The advantages of drone delivery include fast delivery speeds, reduced logistics costs, and the ability to ignore issues such as traffic and obstacles, while also being environmentally friendly and energy-saving.

In terms of autonomous delivery, the application of innovative technologies has made delivery services more efficient. Amazon began implementing autonomous delivery in 2020, using technologies such as autonomous driving algorithms, computer vision, navigation, and sensors to provide delivery services [7]. Autonomous driving algorithms accurately calculate delivery routes to ensure safety. Computer vision helps autonomous vehicles avoid obstacles and recognize traffic signals. Navigation and sensors enable autonomous vehicles to deliver safely and precisely to their destinations. This reduces carbon emissions, lowers delivery costs, and improves transportation efficiency.

3. Case studies of AI in Amazon’s supply chain

These automated robots perform a range of critical warehouse tasks. First, robots are programmed to calculate the shortest and most efficient routes for transporting goods within the warehouse. By minimizing travel distances, they significantly reduce processing time for each operation, leading to substantial time savings and increased operational efficiency. Second, equipped with computer vision technology, robots can scan and visually analyze inventory, allowing them to quickly locate specific items from large stacks of goods. They can also automatically recognize package sizes, ensuring efficient handling and placement. Additionally, robots are designed with obstacle detection capabilities—if a person or object is detected within a designated range, the robot will either stop or adjust its path, enhancing warehouse safety [10]. Third, by automating repetitive and labor-intensive tasks, robots effectively reduce dependence on manual labor, lowering labor costs and improving workplace safety. This allows employees to focus on higher-value tasks, minimizing human errors and optimizing overall productivity.
