Abstract
A reuse evaluation system is a system that performs an evaluation to reuse a catalyst in a state where the catalyst that purifies an exhaust gas of an engine of a vehicle 1 is mounted on the vehicle. The reuse evaluation system includes a deterioration estimator that estimates a degree of deterioration of the catalyst based on an operating state of the vehicle, a reuse setting unit that sets a range of the degree of deterioration of the catalyst as a reuse range of the catalyst according to a usage of reuse of the catalyst, and a reuse determining unit that determines that the catalyst is reusable in the reuse usages when the degree of deterioration of the catalyst estimated by the deterioration estimator is within the reuse range set by the reuse setting unit.
