Abstract

A performance calculation method is provided. In the performance calculation method, shipment inspection data of multiple flow rate controllers are acquired. Further, first performance values indicating, as deviation values, performance of the flow rate controllers are calculated based on the acquired shipment inspection data and first coefficients for items indicating the performance of the flow rate controllers. Further, second performance values indicating, as deviation values, performance of a processing apparatus using the flow rate controllers are calculated based on the calculated first performance values and second coefficients for items indicating the performance of the processing apparatus.
