Traditional maintenance strategies—reactive and preventive—are increasingly proving inadequate in the face of complex logistics and high-performance expectations. This research proposes a predictive maintenance framework that leverages the Internet of Things (IoT) and Machine Learning (ML) to anticipate machinery failures and schedule timely interventions in a supply chain context. The study outlines a multi-layered architecture integrating real-time sensor data acquisition, feature engineering, and advanced machine learning algorithms including Random Forest, XGBoost, and Long Short-Term Memory (LSTM) networks. A case study implementation on a conveyor system within a warehouse demonstrates the system’s capability to predict failures with an accuracy of 94.8% using LSTM, leading to a 60% reduction in unplanned downtime and an overall ROI of approximately 230% annually. Furthermore, the integration with ERP and WMS platforms facilitated automated maintenance planning and improved logistics efficiency. The results affirm that predictive maintenance, empowered by IoT and ML, can significantly enhance asset reliability, reduce operational costs, and increase supply chain resilience. This research also highlights practical implications, limitations, and directions for future work including digital twin integration and AI-driven automation.

Introduction 1.1 Background and Need for Maintenance Optimization Maintenance management is a critical component of industrial operations, directly influencing equipment reliability, production continuity, and operational efficiency. Traditional maintenance strategies, such as reactive maintenance (run-to-failure) and preventive maintenance (based on time or usage intervals), have long been utilized in manufacturing and supply chain systems. However, these strategies have significant drawbacks. Reactive maintenance often results in unexpected equipment failures and unplanned downtime, whereas preventive maintenance may lead to unnecessary servicing, increased labor, and higher spare parts costs (Mobley, 2002). mailto:prasadbalaji94@gmail.com mailto:nuresh.khunte@kalingauniversity.ac.in mailto:vinay.jha@kalingauniversity.ac.in Communications on Applied Nonlinear Analysis ISSN: 1074-133X Vol 32 No. 10s (2025) 1578 https://internationalpubls.com As global supply chains become more complex and time-sensitive, maintenance-related disruptions can create cascading delays throughout the logistics network. In the context of Industry 4.0, where manufacturing systems are increasingly interconnected, the failure of a single machine or node can affect downstream operations, reduce customer satisfaction, and incur substantial financial losses (Lee et al., 2015). Therefore, optimizing maintenance processes is crucial not only for cost-saving and operational continuity but also for enhancing the overall resilience and responsiveness of the supply chain. Modern supply chains demand dynamic, data-driven maintenance strategies that can proactively predict and prevent equipment failure. This shift has led to the adoption of predictive maintenance (PdM) techniques, which use real-time monitoring and intelligent analysis to forecast machinery breakdowns and recommend timely interventions. PdM has the potential to drastically reduce downtime, improve asset utilization, and minimize maintenance costs, thus aligning perfectly with the goals of operational excellence in contemporary manufacturing and logistics settings (Jardine et al., 2006). 1.2 Role of Predictive Maintenance in Modern Supply Chains Predictive maintenance represents a paradigm shift in how industrial systems manage the upkeep of critical assets. Unlike conventional maintenance strategies, PdM relies on data collected from equipment to determine the health and performance of machines. The growing implementation of PdM across supply chain infrastructures is largely attributed to its ability to transform maintenance from a cost center into a strategic function that supports business continuity and competitive advantage (Wang et al., 2020). In modern supply chains, predictive maintenance can be applied to a wide range of assets—from production line machines and automated warehouses to delivery fleets and refrigeration units. By continuously monitoring parameters such as temperature, vibration, pressure, and current consumption, organizations can detect anomalies, wear patterns, and early signs of failure. This helps in planning maintenance activities during non-peak hours or integrating service windows into existing production schedules, thereby reducing operational disruptions (Zonta et al., 2020). Furthermore, the integration of predictive maintenance with supply chain management systems such as Enterprise Resource Planning (ERP), Warehouse Management Systems (WMS), and Transportation Management Systems (TMS) enables automated decision-making. For instance, if a conveyor motor shows signs of imminent failure, the system can automatically reschedule shipments or reallocate resources to ensure minimal disruption to order fulfillment. Such predictive capabilities support agility and efficiency across the entire supply chain, which is essential in today’s volatile and competitive markets (Veldhuis et al., 2019). 1.3 The Emerging Role of IoT and ML in Maintenance The recent technological advances in the Internet of Things (IoT) and Machine Learning (ML) have provided the foundation for the development and implementation of predictive maintenance solutions. IoT enables the deployment of sensors that collect continuous streams of operational data from various equipment components. These sensors can measure parameters such as vibration, Communications on Applied Nonlinear Analysis ISSN: 1074-133X Vol 32 No. 10s (2025) 1579 https://internationalpubls.com temperature, sound, and pressure, converting analog signals into digital data that can be stored, processed, and analyzed (Zhang et al., 2019). Machine Learning, on the other hand, equips systems with the ability to learn patterns from historical data and make informed predictions about future failures. Algorithms such as Random Forest, Support Vector Machines (SVM), and Long Short-Term Memory (LSTM) neural networks are commonly used to analyze time-series data and identify anomalies or degradation trends in machinery behavior (Susto et al., 2015). The integration of ML with IoT-generated data has revolutionized predictive maintenance by enabling condition-based monitoring, early fault detection, and failure prediction with a high degree of accuracy. The synergy of IoT and ML not only enhances the predictive power of maintenance systems but also facilitates real-time decision-making and autonomous control. Cloud computing and edge processing technologies further extend the capabilities of such systems by providing scalable storage, parallel processing, and low-latency communication. As a result, maintenance decisions can be executed in near real-time, improving the responsiveness of the supply chain to equipment health events (Lee et al., 2014). Moreover, with advancements in digital twins and cyber-physical systems, predictive maintenance can be integrated into a virtual model of the supply chain where simulations and scenario analyses can help optimize maintenance scheduling and logistics planning (Grieves & Vickers, 2017). These innovations are setting the stage for smart supply chains that are resilient, adaptive, and self- correcting. 1.4 Research Objectives and Contributions The overarching objective of this research is to explore how the integration of IoT and Machine Learning can enhance predictive maintenance practices within supply chain management. The study aims to develop a framework that collects real-time equipment data, analyzes it using ML algorithms, and provides predictive insights that support maintenance decision-making and supply chain coordination. Specific objectives include: • To identify key supply chain assets suitable for predictive maintenance using IoT. • To select appropriate sensor technologies for capturing equipment health data. • To develop and test ML models for fault detection and failure prediction. • To evaluate the impact of predictive maintenance on operational metrics such as downtime, cost, and delivery performance. • To propose an integrated architecture for implementing predictive maintenance within a digital supply chain ecosystem. 2. Literature Review 2.1 Overview of Maintenance Strategies Maintenance strategies in industrial systems have evolved significantly over the past few decades, transitioning from reactive to predictive methodologies. The traditional reactive maintenance approach, often described as "run-to-failure," involves repairing equipment only after a failure occurs, leading to unplanned downtimes and costly repairs (Mobley, 2002). This method, while Communications on Applied Nonlinear Analysis ISSN: 1074-133X Vol 32 No. 10s (2025) 1580 https://internationalpubls.com simple, can be detrimental in complex supply chain systems where a single breakdown can halt entire operations. To overcome these inefficiencies, preventive maintenance was introduced. This time-based or usage-based strategy focuses on scheduled inspections and part replacements to reduce failure risks. Although preventive maintenance is an improvement over reactive methods, it can result in excessive servicing and premature replacement of parts (Jardine et al., 2006). The emergence of condition-based maintenance (CBM) and predictive maintenance (PdM) has marked a shift toward more intelligent and data-driven maintenance strategies. CBM monitors real- time parameters such as vibration and temperature, while PdM uses historical and real-time data along with statistical or machine learning models to predict when failures are likely to occur (Schwabacher, 2005). PdM has shown to be effective in reducing unplanned downtime, optimizing maintenance schedules, and extending equipment lifespan—crucial benefits in tightly synchronized supply chains. 2.2 IoT Technologies in Maintenance Systems The Internet of Things (IoT) has emerged as a pivotal enabler for real-time equipment monitoring and smart maintenance practices. IoT refers to interconnected devices embedded with sensors, software, and communication technologies that collect and exchange data over networks (Ashton, 2009). In the context of predictive maintenance, IoT devices can continuously monitor critical parameters such as vibration, temperature, humidity, pressure, and electrical current. For instance, sensors embedded in motors can track vibration signatures to detect misalignments, imbalance, or bearing failures. These data are transmitted via protocols such as MQTT, ZigBee, or LoRaWAN to cloud platforms or edge devices for analysis (Ray, 2016). The integration of IoT with cloud infrastructure allows for scalable data storage and remote diagnostics. IoT platforms such as AWS IoT, IBM Watson IoT, and Azure IoT Hub provide ready-to-use frameworks for data ingestion, real-time analytics, and alert generation. These platforms support the real-time decision-making required for predictive maintenance applications in supply chain systems, where asset performance has a direct impact on inventory flow and service level agreements (Verdouw et al., 2016). The Industrial Internet of Things (IIoT) extends these capabilities by incorporating more rugged, industry-grade sensors and integrating with existing SCADA (Supervisory Control and Data Acquisition) systems. The data acquired through IIoT enables condition monitoring at scale, which is especially beneficial for geographically distributed supply chain infrastructures (Lee et al., 2015). 2.3 Machine Learning for Predictive Analytics Machine Learning (ML) has become an essential tool in predictive maintenance, allowing systems to recognize patterns in large datasets and make accurate predictions about future equipment failures. Unlike rule-based systems, ML models learn from historical data to improve over time, offering higher accuracy and adaptability. Supervised learning algorithms such as Support Vector Machines (SVM), Decision Trees, Random Forest, and Logistic Regression have been widely used for classification of failure types and remaining useful life (RUL) estimation (Susto et al., 2015). Unsupervised learning methods Communications on Applied Nonlinear Analysis ISSN: 1074-133X Vol 32 No. 10s (2025) 1581 https://internationalpubls.com like K-means clustering or Principal Component Analysis (PCA) are useful for anomaly detection when labeled failure data is unavailable (Zhang et al., 2019). Recent advances in deep learning, particularly Recurrent Neural Networks (RNNs) and Long Short-Term Memory (LSTM) models, have shown promising results in processing time-series data from IoT sensors. These models capture long-term dependencies and are highly effective in forecasting equipment degradation trends (Zhao et al., 2017). Machine learning also supports data fusion, integrating multiple sensor data streams for holistic equipment health diagnostics. This predictive capability is instrumental in supply chain environments where machine failure can lead to production delays, missed deliveries, and lost revenue (Wang et al., 2020). 2.4 Applications in Supply Chain and Manufacturing Predictive maintenance, enabled by IoT and ML, is increasingly being applied in manufacturing, logistics, and supply chain management (SCM) to reduce operational inefficiencies. In smart factories, PdM solutions are used to monitor CNC machines, conveyors, and robotic arms. These systems enable better utilization of machines and reduce unplanned downtimes, directly improving production throughput (Zonta et al., 2020). In the logistics sector, predictive maintenance is applied to vehicle fleets for monitoring engine health, tire pressure, and fuel efficiency. This reduces the risk of in-transit failures and ensures timely delivery, which is critical in just-in-time (JIT) inventory systems (Baryannis et al., 2019). For example, FedEx and DHL have adopted IoT-enabled predictive analytics to track and maintain their delivery assets proactively. In warehouse management, predictive analytics help maintain automated storage and retrieval systems (AS/RS) and material handling equipment. Early detection of mechanical issues allows scheduling of repairs during low activity hours, minimizing disruptions. Furthermore, predictive maintenance data can be linked with ERP systems to automate procurement of spare parts and update maintenance schedules. This closed-loop integration across the supply chain reduces manual interventions, improves asset management, and enhances visibility (Zhou et al., 2020). 2.5 Gap Analysis Although numerous studies have explored predictive maintenance, several critical gaps remain, particularly in the context of integrated supply chain management: • Lack of standardization: There is a lack of universal frameworks that integrate IoT and ML for predictive maintenance across various types of equipment and supply chain functions (Lee et al., 2014). • Limited end-to-end integration: Many existing implementations focus only on machinery health and overlook integration with higher-level SCM systems like ERP or logistics platforms (Veldhuis et al., 2019). • Insufficient real-time deployment: While most models perform well in simulations, few are validated in real-time industrial settings with varying operating conditions. Communications on Applied Nonlinear Analysis ISSN: 1074-133X Vol 32 No. 10s (2025) 1582 https://internationalpubls.com • Data availability and quality: Effective ML models depend heavily on the availability of large, high-quality labeled datasets, which are often difficult to obtain in industrial environments (Zhang et al., 2019). • Scalability and Cost: Many IoT and ML-based systems are not easily scalable for small-to- medium enterprises (SMEs) due to cost and complexity. Therefore, there is a pressing need for research that bridges the gap between technical innovation and practical implementation—specifically, studies that present integrated, cost-effective, and scalable frameworks for predictive maintenance across supply chains using IoT and ML technologies. 3. Methodology 3.1 System Architecture for Predictive Maintenance The proposed system architecture is a multi-layered framework integrating IoT-enabled data acquisition, cloud/edge processing, machine learning-based analytics, and decision-making interfaces. The architecture consists of four key layers: • Sensor Layer: Includes physical sensors attached to machinery for capturing real-time operational data (temperature, vibration, pressure, etc.). • Communication Layer: Facilitates data transmission via wireless protocols (e.g., MQTT, ZigBee, Wi-Fi) to edge or cloud platforms (Ray, 2016). • Processing Layer: Employs data preprocessing and ML-based analytics using platforms like Python, TensorFlow, or Azure ML. • Application Layer: Includes dashboards, alerts, and integration modules for ERP/WMS systems, enabling real-time maintenance planning. This architecture supports scalable deployment, real-time feedback, and interoperability across different supply chain functions. 3.2 Data Collection via IoT Sensors (Temperature, Vibration, Humidity, etc.) Data collection is performed through industrial-grade IoT sensors installed on critical machinery components such as motors, bearings, gearboxes, and compressors. Key sensors include: • Vibration Sensors (Accelerometers): For identifying imbalances and misalignments. • Temperature Sensors (RTDs or Thermocouples): To detect overheating due to wear or friction. • Humidity Sensors: Useful in environments where moisture affects machinery. • Current and Voltage Sensors: To monitor power anomalies or electrical issues (Lee et al., 2015). The sensor data is collected at predefined sampling rates (e.g., 1 Hz to 10 kHz) and stored in time- stamped formats for real-time monitoring and historical trend analysis. 3.3 Data Preprocessing and Feature Selection Raw data from IoT sensors often contains noise, outliers, or missing values. Therefore, preprocessing is a critical step: • Data Cleaning: Removing outliers using z-score or IQR methods. Communications on Applied Nonlinear Analysis ISSN: 1074-133X Vol 32 No. 10s (2025) 1583 https://internationalpubls.com • Normalization/Standardization: Scaling data for ML compatibility. • Data Imputation: Using interpolation or k-NN to fill missing values. • Feature Engineering: Extracting statistical features such as RMS, kurtosis, skewness, spectral entropy, and frequency bands (Zhang et al., 2019). Feature selection techniques such as Recursive Feature Elimination (RFE) and Principal Component Analysis (PCA) are used to reduce dimensionality and retain only the most relevant indicators for failure prediction. 3.4 ML Algorithms Used (Random Forest, XGBoost, LSTM, etc.) Multiple machine learning algorithms are evaluated for predicting equipment health: • Random Forest: For classification of fault categories using ensemble decision trees. • XGBoost: Known for its performance in handling imbalanced datasets and optimizing predictive accuracy (Susto et al., 2015). • LSTM (Long Short-Term Memory): Ideal for time-series data to learn long-term dependencies in sensor trends and detect gradual degradation (Zhao et al., 2017). Models are trained using historical labeled failure data, with target labels such as “Healthy”, “Degrading”, and “Critical”. 3.5 Model Training and Validation Process The model training and evaluation process involves: • Train-Test Split: Typically 70-30 or 80-20 ratios. • Cross-Validation: K-fold validation (k=5 or 10) to reduce overfitting. • Evaluation Metrics: Accuracy, F1-score, Precision, Recall, and RMSE for regression models. Hyperparameter tuning is performed using GridSearchCV or Bayesian optimization. The best- performing model is deployed on the cloud or edge device for real-time inference. 4. Case Study / Implementation 4.1 Description of Equipment/Process Studied The implementation was conducted on a conveyor belt system used in a warehouse facility within the supply chain network of an FMCG company. The conveyor system is integral to the continuous flow of goods and involves motors, pulleys, gearboxes, and rollers—components prone to wear and failure. The primary failure modes observed include motor overheating, bearing wear, and misalignment of rollers, which historically led to 10-12 hours of unplanned downtime per month. 4.2 Sensor Setup and IoT Framework The following sensor configuration was used: • 3-axis vibration sensors (on bearings) • PT100 RTD temperature sensors (on motor housing) • Current transducers (on motor power supply) Communications on Applied Nonlinear Analysis ISSN: 1074-133X Vol 32 No. 10s (2025) 1584 https://internationalpubls.com These sensors were connected to an IoT gateway (Raspberry Pi 4) equipped with Wi-Fi and LTE communication modules. Data was transmitted to an AWS IoT Core cloud platform for processing. The edge device handled preliminary filtering and FFT analysis before pushing features to the cloud. 4.3 Dataset Description and Time Period The data collection period spanned 8 weeks, generating a dataset of approximately 1.2 million data points. The data included: • Timestamped readings at 1 Hz sampling rate • Operational status logs • Maintenance and failure logs (used for labeling) Labels were assigned based on technician notes and breakdown history. The dataset was divided into training (70%) and testing (30%) sets. 4.4 Predictive Model Application and Monitoring The best-performing model, LSTM, achieved an F1-score of 92% for predicting motor failures within a 48-hour horizon. A dashboard was created using Grafana, which provided: • Live sensor data • Predicted failure risk (Low, Medium, High) • Alerts via SMS/email When the risk threshold exceeded 0.8 (on a 0–1 scale), a maintenance ticket was auto-generated in the company's CMMS (Computerized Maintenance Management System). 4.5 Integration with SCM Platform (ERP/WMS/etc.) The predictive maintenance module was integrated with the organization’s SAP ERP and Oracle WMS platforms through REST APIs: • ERP Integration: Triggered spare part requisitions and updated inventory in real time. • WMS Integration: Re-routed orders to alternate conveyor lines when a machine was flagged as "at risk." This integration allowed proactive decision-making and minimized disruption in warehouse operations and outbound logistics. 5. Results and Discussion 5.1 Model Performance Metrics (Accuracy, Precision, Recall, RMSE) The proposed predictive maintenance system was evaluated using several machine learning models including Random Forest (RF), XGBoost, and Long Short-Term Memory (LSTM). After training and testing on the preprocessed dataset, LSTM outperformed other models due to its ability to capture temporal dependencies in time-series sensor data. Table 1.1 The model evaluation metrics are summarized Model Accuracy Precision Recall F1-Score RMSE (for RUL) Random Forest 88.60% 86.30% 84.90% 85.60% 0.175 XGBoost 91.20% 89.70% 88.10% 88.90% 0.148 LSTM 94.80% 93.50% 91.70% 92.60% 0.098 Communications on Applied Nonlinear Analysis ISSN: 1074-133X Vol 32 No. 10s (2025) 1585 https://internationalpubls.com LSTM provided the most reliable predictions with the lowest Root Mean Square Error (RMSE), ensuring accurate forecasts of equipment failures and remaining useful life (Zhao et al., 2017). The high F1-score indicates a good balance between precision and recall, which is crucial in minimizing false positives and negatives in a real-time maintenance environment. 5.2 Maintenance Scheduling Improvements The implementation of the predictive model enabled a shift from reactive and preventive schedules to dynamic, condition-based maintenance planning. Before implementation, maintenance schedules were based on fixed time intervals or reactive triggers post-failure. With the deployment of the LSTM model: • 70% of maintenance tasks were transitioned to predictive schedules. • Maintenance alerts were triggered 48–72 hours in advance based on risk predictions. • Work orders were automatically generated and synchronized with ERP systems. This allowed maintenance personnel to optimize resource allocation, reduce labor redundancy, and coordinate maintenance during non-peak hours, thereby avoiding disruption to operations (Wang et al., 2020). 5.3 Reduction in Downtime and Supply Chain Delays A key performance indicator for evaluating the success of the predictive maintenance system was the reduction in unplanned equipment downtime. The system led to the following improvements: • Unplanned downtime reduced by 60%, from an average of 12 hours/month to less than 5 hours/month. • On-time delivery rate improved from 92% to 97%, reducing late shipments. • Line stoppage incidents dropped by 45%, ensuring smoother production flow. These improvements had a ripple effect on the supply chain, preventing stockouts, order cancellations, and delivery rescheduling (Zonta et al., 2020). Predictive alerts enabled warehouse managers to reroute operations or activate backup systems before disruptions occurred. 5.4 Economic Benefits and ROI The economic impact of implementing IoT and ML-driven predictive maintenance was analyzed using a cost-benefit approach. Key financial outcomes include: • Maintenance costs reduced by 28%, primarily through optimized labor deployment and just-in-time part replacement. • Loss due to unplanned downtime reduced by ₹4.6 lakhs/month. • Sensor and system setup costs recovered within 6 months, indicating a short payback period. • Return on Investment (ROI) for the predictive maintenance system was calculated at ~230% annually.

Conclusion 6.1 Summary of Key Findings This study successfully developed and implemented an IoT and Machine Learning (ML)-based predictive maintenance framework tailored for supply chain environments. Through the deployment of real-time sensor data collection, advanced data preprocessing, and machine learning algorithms such as LSTM, the research demonstrated that predictive maintenance can significantly enhance equipment reliability and supply chain continuity. Key findings include: • The LSTM model achieved the highest performance with an accuracy of 94.8% and F1- score of 92.6%, outperforming Random Forest and XGBoost. • The system facilitated a 60% reduction in unplanned downtime, leading to enhanced delivery timelines and production efficiency. • The integration of predictive insights with ERP and WMS platforms enabled automated maintenance scheduling, reducing human intervention and improving response time. • A return on investment (ROI) of approximately 230% annually validated the financial feasibility of the solution. Overall, the proposed framework proved effective in shifting maintenance strategies from reactive and preventive to data-driven, intelligent, and proactive models that directly benefit the supply chain. 6.2 Practical Implications for Industry The practical applications of this research extend to several industrial sectors, especially those relying heavily on continuous production and logistics operations such as manufacturing, automotive, food processing, and e-commerce. The key implications include: • Enhanced Asset Management: The predictive model supports real-time monitoring and proactive maintenance, increasing machinery lifespan and reducing spare part wastage. • Operational Efficiency: Timely maintenance reduces disruptions in the flow of materials and goods, ensuring better throughput and fulfillment rates. Communications on Applied Nonlinear Analysis ISSN: 1074-133X Vol 32 No. 10s (2025) 1587 https://internationalpubls.com • Data-Driven Decision Making: Maintenance and supply chain managers can base their scheduling and inventory decisions on real-time equipment health rather than estimates. • Automation Readiness: The integration with ERP and WMS platforms sets the foundation for fully automated maintenance workflows within smart factories and warehouses. This research demonstrates that predictive maintenance is not just a maintenance strategy but a strategic enabler for competitive and agile supply chains. 6.3 Limitations While the results are promising, this study has a few limitations that warrant consideration: • Limited Dataset Size and Scope: The case study was confined to a specific warehouse conveyor system over a short time frame (8 weeks). Broader implementation across diverse assets could yield deeper insights. • Sensor and Infrastructure Costs: Initial setup for IoT infrastructure can be cost-prohibitive for small-scale enterprises. • Dependence on Data Quality: The accuracy of predictions heavily depends on the quality and quantity of collected data. Missing or noisy data can impair model performance. • Model Interpretability: Deep learning models like LSTM, although accurate, often lack transparency, making it difficult for engineers to understand the decision process. 6.4 Future Scope (AI-based Automation, Digital Twins, etc.) Several opportunities exist for extending this research in both depth and breadth: • Digital Twin Integration: Future work can explore integrating predictive maintenance with digital twins—virtual models of physical systems—for real-time simulation, diagnostics, and prescriptive maintenance. • Reinforcement Learning and Adaptive Models: Incorporating reinforcement learning can allow the system to self-improve over time by learning from new failure cases and maintenance outcomes. • Multi-Asset and Multi-Site Deployment: Scaling the solution to monitor multiple types of equipment across geographically distributed supply chains could enhance its robustness and generalizability. • Cybersecurity Enhancements: With increasing connectivity, future studies should address the security of maintenance data and system resilience against cyber threats. • Sustainability and Green SCM: Predictive maintenance contributes to sustainability by reducing energy waste and material consumption. Further research could quantify and optimize this impact in green supply chain models. In conclusion, predictive maintenance using IoT and machine learning presents a powerful approach to optimizing industrial operations. By bridging the gap between asset health and supply chain agility, such systems represent a significant leap toward smart, self-aware, and resilient manufacturing ecosystems in the Industry 4.0 era.
