PROBLEM TO BE SOLVED: To provide an anticipation model maintenance system, a method for maintaining an anticipation model, and an anticipation model maintenance program that can sufficiently reduce degradation of the accuracy of anticipation due to change of manufacturing processes.;SOLUTION: An anticipation model maintenance system 10 includes a control unit 11. The control unit 11 includes a learning data creation unit 14, a new anticipation model creation unit 15, an evaluation data creation unit 16, and an operational anticipation model selection unit 17. The learning data creation unit 14 creates learning data used to create a new anticipation model. The anticipation model creation unit 15 creates a new anticipation model, using the learning data. The evaluation data creation unit 16 creates evaluation data used to evaluate the anticipation model and the new anticipation model. The anticipation model selection unit 17 evaluates the anticipation model and the new anticipation model, using the evaluation data, and selects one with the higher evaluation of the anticipation model and the new anticipation model as an operational anticipation model.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2019,JPO&INPIT
