Abstract: Film evaluation system and evaluation method thereof are provided. The film evaluation system includes a measurement unit, an observation unit, an adaptive algorithm unit, an estimation unit, and a health state calculation unit. The measurement unit obtains an initial state parameter set corresponding to a film. The observation unit is connected to the measurement unit and obtains a flux observation value according to the initial state parameter set. The adaptive algorithm unit is connected to the observation unit and obtains a flux prediction value according to the initial state parameter set. The estimation unit is connected to the adaptive algorithm unit and obtains a diffusion rate and a flow resistance by comparing the flux observation value and the flux prediction value. The health state calculation unit is connected to the estimation unit and obtains a health state of the film according to the diffusion rate and the flow resistance.
