Abstract: The management computer of a mounting system, when productivity is lowered, identifies an operator and work type from a work history, retrieves a management value P for the identified work type for the identified operator, and increases the management value P by an increment of “1.” Then, the management computer of the mounting system, when judging that management value P is at least second threshold value P2, applies a performance restriction on the identified operator for the work of the identified work type. Thus, it is possible to curtail lowered productivity due to the same work by the same operator being repeated.
