Cell controller for optimizing motion of production system including industrial machines

A cell controller for managing a production system having a plurality of industrial machines operated by an operation program, the cell controller comprising:

• a system operational information analyzer configured to analyze time-series operational information received from the industrial machines via a network, so as to find a part in the system which generates an adverse effect on a cycle time of the entire production system;
• a state quantity analyzer configured to analyze a state quantity including data of a sensor for detecting a state of the industrial machines, so as to calculate a degree of margin of motion of each industrial machine;
• a program modifier configured to automatically modify a velocity or acceleration in the operation program based on the degree of margin calculated by the state quantity analyzer;
• and
• a simulator configured to execute an operational simulation of the production system in order to confirm a modification result of the operation program.
