A cell controller capable of optimizing the operation of a production system having a plurality of industrial machines operated by an operation program. The cell controller includes: 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 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; and a simulator configured to execute an operational simulation of the production system in order to confirm a modification result of the operation program.

A manufacturing management system capable of appropriately evaluating a degree of consumption of each component of a manufacturing machine, and efficiently operating a manufacturing cell including the manufacturing machines. A control unit of a cell controller has: a manufacturing machine information receiving part configured to receive manufacturing machine information regarding an operational history of each component constituting the manufacturing machine; a component degree of consumption calculating part configured to calculate a weighed degree of consumption of each component, based on the manufacturing machine information and a predetermined weight of each component; a manufacturing machine degree of consumption calculating part configured to calculate a degree of consumption of each manufacturing machine, based on the weighed degree of consumption of each component; and a manufacturing machine selecting part configured to select a manufacturing machine to be used in the manufacturing cell, based on the degree of consumption of each manufacturing machine.

A state change management system of a manufacturing cell in a cell control system receives, from the manufacturing cell, event information items in different forms generated in multiple manufacturing machines constituting a manufacturing cell, via a communication device, to thereby monitor the changes in the states of the multiple manufacturing machines. Moreover, the state change management system converts the received event information items in the different forms into a standardized form, and outputs the event information items in the standardized form to a production planning device that performs production planning of a product manufactured by the manufacturing cell via the communication device.
