Abstract
A joint optimization model of maintenance and operation of high-speed train fleets is
established with the optimization objective of minimizing the total costs, considering
dynamic passenger flow and maintenance resources. A new maintenance strategy CCPM
(Coordinating Conflicts Preventive Maintenance) is proposed to optimize the problem.
The effectiveness of the model and the strategy are verified by numerical examples. The
comparison between the strategy in the paper and the existing approach proves that the
new strategy is more effective and shows the importance of considering dynamic passenger flow. The model and the strategy provide decision support for the actual high-speed trains operation and maintenance program. This study also offers new ideas to the subsequent research on preventive maintenance of high-speed trains.
期刊介绍：
The quarterly Eksploatacja i Niezawodność – Maintenance and Reliability publishes articles containing original results of experimental research on the durabilty and reliability of technical objects. We also accept papers presenting theoretical analyses supported by physical interpretation of causes or ones that have been verified empirically. Eksploatacja i Niezawodność – Maintenance and Reliability also publishes articles on innovative modeling approaches and research methods regarding the durability and reliability of objects.
