ABSTRACT:
A real-time monitoring system and method for processes or tools. Historical data for processes or tools is first collected and abnormal data then analyzed using statistical analysis. At least one control chart model is designated according to the analysis result, and model parameters and linking settings related to control chart models are stored in a database. Next, a real-time monitoring model is created by merging control chart models, using model-creating technologies, according to abnormal-state causes, the model parameters, and the linking settings, and several monitoring models are then merged as a real-time monitoring model. Finally, operating states of the processes or tools are displayed using the real-time monitoring model according to real-time data or the historical data stored in the database.
