Abstract: Secular change data on each unit of denitration catalysts (101) is managed based on data obtained by a periodic maintenance management (step S110) and a daily management (step S120), and management of a secular change and a performance variation prediction until a next periodic check is performed (step S130). It is determined whether a deterioration of the denitration catalyst (101) reaches a level at which a performance of an exhaust-gas denitration system (100) cannot be maintained (step S140). If it is determined that the deterioration is positive (“deteriorated” at step S140), then a regeneration, a replacement, or an addition of the denitration catalyst (101) is performed (steps S150, 160, and 170), the denitration catalyst is altered if necessary (step S180), and the denitration catalyst (101) is not replaced or regenerated (step S190) if it is recognized that the catalyst is usable (“usable” at step S140).
