Railroad maintenance support system, railroad maintenance support method

A railroad maintenance support system, comprising:

• a processer, and
• a memory unit, wherein
• the processer estimates failure prediction model, for each of multiple railroad facilities, used to predict the failure of railroad facility, and stores in the memory unit,
• in the estimation of the failure prediction model,
• performs the process of estimating a failure prediction model of second railroad facility, which includes an explanatory variable is a failure prediction of failure prediction model of first railroad facility already estimated and stored in the memory unit,
• outputs overall maintenance cost by maintenance based on failure prediction of failure prediction model for each railroad facility.

A railroad maintenance support method performed using a railroad maintenance support system including a processor, and a memory unit, comprising:

• the processor inputs maintenance accuracy which is information about the accuracy of maintenance of railroad facility, estimates deterioration prediction model, for each of multiple railroad facilities, used to predict the deterioration of railroad facility with the maintenance accuracy as an explanatory variable, and stores in the memory unit,
• outputs overall maintenance cost by maintenance based on deterioration prediction of deterioration prediction model for each railroad facility,
• wherein,
• when estimating deterioration prediction model for each of the multiple railroad facilities, performs the process of estimating a deterioration prediction model of second railroad facility, which includes an explanatory variable is a deterioration prediction of deterioration prediction model of first railroad facility already estimated and stored in the memory unit.
