A Machine Learning Approach to Supply Chain Vulnerability Early Warning System - Evidence from U.S. Semiconductor Industry

Aug 3, 2026

A machine learning-based early warning system is developed to detect and predict defects in semiconductor devices across the U.S. semiconductor supply chain. The framework integrates network research models with hybrid Graph Neural Network (GNN) and Long Short-Term Memory (LSTM) architectures, ingesting multiple data streams such as real-time measurements, performance instrumentation, and business indicators. Over 18 months with 158 manufacturers, the system achieved 94.3% accuracy, estimated major-event impact 15.3 days ahead, and reduced impact by 64%, producing cost estimates of $37.2 million while outperforming traditional baselines.

Introduction 1.1 Research Background and Motivation Semiconductor equipment represents an important process in today's global economy, with its impact affecting many industries and industries. Recent years have seen unprecedented challenges in the semiconductor industry, ranging from regional conflicts to natural disasters and market volatility. The increasing complexity and integration of semiconductor devices have widened their vulnerability to various types of disruptions, requiring more sophisticated methods for risk management and early warning[1] . The U.S. semiconductor industry, accounting for 47% of the global market share in chip sales, faces particular challenges because it relies on complex international supplies. The high production capacity in particular areas has created points of failure, as shown by the recent chain disruptions that have affected many industries in back These impacts highlight the urgent need for early warning systems capable of predicting and mitigating adverse product events[2][3] . Machine learning technology has emerged as a powerful tool in supply chain management, providing new possibilities for predictive analytics and risk assessment. The integration of machine learning with traditional inventory management systems presents opportunities to develop early warning systems and be more robust[4] . These systems can process large amounts of data from multiple sources, identify patterns, and predict potential disruptions before they cause serious problems. Network studies have shown great value in identifying the network infrastructure, especially in identifying critical nodes and potential vulnerabilities[5] . The use of network-based analysis combined with machine learning algorithms provides a comprehensive framework for understanding and predicting product risks in the semiconductor industry[6] . This integration enables accurate analysis of system risks and potential impacts from connected devices. 1.2 Research Objectives This research is designed to develop a machine learningbased earl
