AI-Enabled Predictive Maintenance Frameworks for Lifecycle Optimization of Capital-Intensive Industrial Equipment

Abstract: This manuscript develops a scholarly framework for understanding how artificial intelligence can reshape predictive maintenance for capital-intensive industrial equipment across its operational life cycle. It argues that maintenance intelligence should not be treated as a narrow algorithmic exercise but as an integrated research, engineering, and governance problem linking uncertainty analysis, causal reasoning, predictive modeling, data infrastructure, and institutional accountability. Across manufacturing, energy, and process industries, equipment decisions are made under incomplete information, heterogeneous operating regimes, and long asset horizons; the central challenge is therefore to design maintenance systems that are technically reliable, economically defensible, operationally usable, and publicly governable. The chapters assemble a coherent progression from conceptual foundations and research design to statistical explanation, machine-learning prediction, scalable analytics lifecycles, and sectoral implementation. The manuscript produces a set of research outputs oriented to advanced academic and professional use: design logics for maintenance studies, model evaluation matrices, lifecycle data architectures, MLOps control practices, and governance artifacts for human oversight and policy alignment. The resulting account is intended for researchers seeking rigorous conceptual integration, practitioners building deployable decision systems, and policymakers concerned with resilience, safety, and industrial competitiveness in data-intensive maintenance environments.
