OPTIMIZING MAINTENANCE STRATEGIES OF COIL SHOP: A DIFFERENTIAL EQUATION APPROACH

This paper presents a control process of reliability models for key subsystems in a coil shop by advanced differential equations approach. The goal is to optimize the maintenance scheduling process for the critical subsystems, enabling the system to operate at maximum efficiency. Maintenance strategies significantly influence this outcome, and selecting the right strategy is not trivial. The designed control process model can be applied by administrative setup in manufacturing concerns. The 3-state models here are developed for the dynamic behavior of the system under the impact of preventive maintenance strategies. Both maintenance and repair of the units are perfect. The numerical analysis of the system is also discussed to compare the behavior of the present model and the proposed models. The comparison helps in findings the production-affecting factors and addresses maintenance planning gaps for critical subsystems. This approach aims to optimize the entire manufacturing system, potentially increasing profitability.
