The supply chain fragmentation, geopolitical limitations and the fast rates of component obsolescence in the contemporary AI-hardware ecosystem require the strong diagnostic automation structures. This paper outlines a new architecture to integrate in-line hardware diagnostics, federated anomaly detection and automated remedial workflows to augment resilience of AI-specific hardware assets (e.g. neural-accelerator boards, memory modules) in the context of distributed supply chains. The suggested system leverages embedded sensors and telemetry based on board-level power/thermal/failure-event logs (instrumented through the use of IoT gateways) and consolidated through the use of secure edge-cloud pipelines. The federated learning module is used to train localized anomaly-detection models (e.g., variational autoencoders) at all nodes of the supply chain without losing data sovereignty. On the occurrence of a diagnostic signature, e.g. an increase in leakage current, non-standard thermal gradient across AI accelerator units, or failure during repeated operation in a stack, the system initiates automated correction measures: dynamically re-routed hardware units, non-standard scoring of suppliers through blockchain-based traceability. Simulations of supply chains in the form of digital twins are used to execute what-if risks of disruption of components and hardware diagnostics to focus on risk mitigation plans. The diagnostic system combines a real-time repair-automation code (e.g., firmware rollback, self-healing microcontrollers) with procurement procedures to minimize the mean time to detect
(MTTD) and mean time to recover (MTTR). A synthetic supply-chain testbed evaluation demonstrates a 45 percent reduction in defect isolation time and a 30 percent decrease in hardware lead-time upheavals in a multi-tier supplier failure condition. The study paves the way towards the intersection of AI hardware diagnostics, supply-chain automation, and resilience engineering, which offers operators of distributed manufacturing networks a blueprint of integrating autonomous diagnostic loops into fragmented supply-chain settings.
