Patent ID: 7752826

Claim:
A production system, comprising: a supply unit configured to supply articles; a plurality of combination weighing devices with each of the combination weighing devices being configured to perform combination weighing of the articles supplied from the supply unit to the combination weighing devices; a storage unit configured to store a production schedule of the articles; an operating rate detection unit configured to detect operating rates of the combination weighing devices, the operating rate being defined as a ratio of a current set capacity to a maximum set capacity; a determination section configured to determine whether the production schedule will be completed if the combination weighing devices continue to operate at the detected operating rates; a yield rate detection unit configured to detect yield rates of the combination weighing devices, the yield rate being defined as a ratio between a number of actual processing routines in the combination weighing device and a number of acceptable products processed by the combination weighing device; and a control unit that varies the operating rate of each of the combination weighing devices individually so that the yield rates detected by the yield rate detection unit do not fall below a prescribed yield rate, when the determination section determines the production schedule will not be completed.
