The wheel/rail contact relationship has a great impact on the security and reliability of metro vehicles in service. In particular, wear modeling and maintenance optimization for wheels play significant roles with regard to both safety and cost. Acknowledging that re-profiling is not the only strategy for dealing with wheel wear, the authors have developed a more advanced optimization approach that combines another two strategies, namely, turning and multi-templates, to give as near an optimal solution as possible. In this paper, re-profiling, turning, and multi-template use are discussed separately. Then a hybrid optimization strategy for metro wheel maintenance is proposed, with the aim of maximizing wheel life while minimizing relevant costs. An initial case study on the Shanghai Metro system shows that the proposed approach is able to find the reasonable solution for the maintenance strategy optimization.
