Optimization of Operation Costs in Complex, Multi-State, Aging Technical Systems
1 Gdynia Maritime University, Gdynia, Poland
ABSTRACT: This paper presents a methodological framework for the joint optimization of operation costs and safety performance in complex, multi-state ageing technical systems. Two original models of system operation cost are proposed: one based on total operation time, and the other on operation within safety state subsets. The models are integrated with linear programming procedures and applied to a real-world maritime transport system. The approach enables a balanced consideration of operational efficiency and system reliability, offering a structured way to support decision making in the management of ageing infrastructure. The methodology relies on both statistical operational data and expert knowledge. Potential extensions of this work include incorporating external factors such as environmental conditions, as well as integrating repair, preventive maintenance, and evolutionary multi objective optimization algorithms to enhance resilience and sustainability in critical technical systems.
