Using　multi-resolution　modeling　(MRM)　theory,　multiple　simulation　models　for　the　train　control　system　with　different　emphasis　can　be　established.　In　the　process　of　describing　the　same　object　with　multiple　resolution　models,　the　consistency　of　the　multi-resolution　models　should　be　considered.　Ontology　mapping　based　output　information　consistency　maintenance　method　was　proposed　to　maintain　output　information　consistency　of　multi-resolution　model.　To　value　the　importance　of　each　atom　information,　AHP　based　evaluation　method　was　used.　Output　information　from　multi-resolution　models　for　the　train　operation　control　system　was　mapped　and　compared　based　on　this　method.　The　effectiveness　of　the　proposed　method　was　verified　by　a　simulation　example　of　inconsistent　event　planting.　©　2016,　Science　Press.　All　right　reserved.
