Introduction

The advent of the IIoT has redefined predictive maintenance in autonomous manufacturing by enabling real-time monitoring, data-driven decision-making, and proactive fault prevention [1]. Traditional maintenance strategies, such as reactive and preventive approaches, often lead to unnecessary downtime, increased operational costs, and inefficient resource utilization [2,3]. In contrast, predictive maintenance leverages IIoT sensors, machine learning models, and big data analytics to forecast equipment failures before occur, thereby optimizing maintenance schedules and improving asset reliability [4]. Implementing scalable and interoperable IIoT-driven predictive maintenance systems presents significant challenges due to the heterogeneity of industrial environments, the complexity of data integration, and the need for real-time decision-making under resource constraints [5,6]. Addressing these challenges requires advanced architectural frameworks capable of handling high-frequency sensor data, intelligent workload distribution, and secure data exchange across diverse industrial networks [7].

Scalability was a fundamental requirement for IIoT-based predictive maintenance systems, as industrial environments generate vast amounts of high-velocity data from numerous interconnected devices [8]. Centralized cloud-based architectures often struggle with processing large-scale industrial data in real-time, resulting in latency issues and inefficient utilization of computational resources [9]. To overcome these limitations, distributed computing paradigms such as edge and fog computing have been introduced, allowing data processing to be performed closer to the source [10,11]. Edge computing enables localized decision-making by analyzing sensor data in real-time, reducing dependence on cloud infrastructure and ensuring minimal latency [12]. Additionally, AI-driven resource allocation techniques optimize computational efficiency by dynamically distributing workloads across edge and cloud environments [13]. These advancements enhance system responsiveness and support the seamless scalability of predictive maintenance solutions in complex industrial settings [14].
