摘要: AbstractIn order to optimally schedule railway track maintenance operations, it is essential accurately estimate future conditions. This study proposes a geometry degradation model that considers uncertainties in the forecast by defining reliability parameter. The integrated multiobjective optimization approach assess strategies considering cost–reliability trade off. Finally, numerical application of real case presented. results show usefulness proposed guarantee required performance with effective investments.
