Research on preventative rail maintenance to date majors small or artificial problem instances, not applicable real-world use cases. This article tackles large, scheduling problems. Maintenance costs and availability of the infrastructure need be optimized, while adhering a set complex constraints. We develop compare three generic approaches: an evolution strategy, greedy metaheuristic, hybrid ...

The optimal predictive, preventive, corrective and opportunistic maintenance policies play an important role in the success of sustainable operations. This study discusses a new energy efficiency-related policy optimization method, which is based on failure data status information from both physical system digital twin-based discrete event simulation. presents functional model, mathematical mod...
