In a component mounting system having an inspection device performing a mounting inspection after component mounting, a correction value for correcting a mounting program is calculated based on board inspection information including fed-back component position deviation information, a component is mounted on a board in accordance with the mounting program corrected based on the calculated correction value, and a present value based on most recent board inspection information and a pre-correction evaluation value are displayed together on an evaluation value display screen as evaluation values representing accuracy at a time of the mounting based on the board inspection information during this component mounting work, the pre-correction evaluation value being calculated based on a temporary position deviation amount pertaining to a case where it is assumed that no correction based on the calculated correction value has been performed.

A Self-monitoring manufacturing system adapted to produce at least one object. The system includes at least a first processing facility adapted to perform a respective first processing step with the object, and a production control unit, wherein the production data comprises nominal pre-processing object data. A production monitoring unit for checking a pre-processing object state of the object is arranged, such unit being adapted to obtain actual property data of the object in-line of the production in-advance of applying the first processing step, to generate deviation data by comparing the actual property data with the production data for the first processing step, and to provide the deviation data for performing the first production step with the first processing facility in deviation-adjusted manner.
