Analysis apparatus and analysis system

An analysis apparatus making predictions about the quality of conditions of a production facility or the quality of conditions of a production object in a process of producing the production object by the production facility, comprising:

• a plurality of predictors making predictions about the quality by using different analysis methods based on data concerning the production facility;
• a selection unit selecting the plurality of predictors in use from the plurality of predictors;
• an overall predictor calculating a comprehensive prediction result about the quality based on a plurality of prediction results obtained by the plurality of predictors in use;
• and
• a prediction accuracy calculation unit calculating accuracies of predictions made by the respective plurality of predictors based on prediction results made by the respective plurality of predictors and inspection results about the quality,
• wherein the selection unit selects the plurality of predictors in use from the plurality of predictors based on prediction accuracies calculated by the prediction accuracy calculation unit.
