Material control system for cold rolled steel sheets and method for generating material prediction model for cold rolled steel sheets

A material control system for cold rolled steel sheets, the material control system comprising:

• a programmable logic controller configured to obtain process data of a cold rolled steel sheet already produced;
• a process controller configured to control a process of manufacturing a cold rolled steel sheet according to process data of the programmable logic controller;
• a model generation unit configured to learn a learning data set in advance and to generate a prediction model predicting a material in a length direction of the cold rolled steel sheet to be produced;
• and
• a manufacturing execution system configured to transmit information to and receive information from the process controller, to receive a prediction value of the prediction model generated by the model generation unit and to manage production of the cold rolled steel sheet to be produced,
• wherein the learning data set includes:
• hot rolling process data included in process data from the programmable logic controller;
• material data and component data from the manufacturing execution system;
• and
• data obtained by mapping a measurement position between cold rolling and annealing process data included in process data from the programmable logic controller.
