Claim One:
1. A computer implemented predicting cycle time, comprising the following steps: collecting a plurality of known sets of data, the known sets of data having at least two reference cycle times and an objective cycle time; using a clustering method to classify the known sets of data into a plurality of clusters; using a decision tree method to build a classification rule of the clusters; building a prediction model of each cluster, the prediction model indicating the relationship of the variation between the reference cycle times and the objective cycle time; preparing a predicted set of data, the predicted set of data having of at least two or more known reference cycle times and one unknown objective cycle time; using the classification rule to determine that to which clusters the predicted set of data belongs; and using the prediction model of the cluster to estimate the objective cycle time of the predicted set of data, acquiring a prediction value for the objective cycle time.
