Abstract: A model building system, a quality prediction system, and a quality management system using the same are provided. The quality management system includes the quality prediction system, a measurement device, and a quality inspection device. The quality prediction system includes the model building system and a model application device. The model building system includes a data transformation device and a model training device. The data transformation device transforms raw measured data, including measurement properties of products, to sets of cluster data and multi-dimensional metadata corresponding to the measurement properties. The model training device creates a prediction model according to the cluster data, the quality inspection results, and the multi-dimensional metadata corresponding to a portion of the products, and then modifies structural parameters of the prediction model according to the raw measured data and the quality inspection results corresponding to the other portion of the products.
