Production system and production method

A production system includes a first manufacturing machine and a second manufacturing machine. The production system also includes a production control unit configured to control productivities of the first and second manufacturing machines. In response to detecting a breakdown sign in the first manufacturing machine, a stop time of the first manufacturing machine is predicted. After the detection of the breakdown sign and before the first manufacturing machine stops, the productivity control unit updates the productivities of the first and/or second manufacturing machines, causing the first manufacturing machine and/or the second manufacturing machine to have an updated productivity equal to or greater than its original productivity, such that a total productivity of the first manufacturing machine and the second manufacturing machine increases.
