Slitter-winder and fiber web production line control system

A system for controlling performance of a slitter-winder and a fiber web production line, the system comprising:

• an advisor unit comprising at least one processor and at least one memory unit including computer program code;
• wherein the at least one memory unit and the computer program code are configured, with the at least one processor, to cause the advisor unit to generate and transmit signals comprising first control data to the slitter-winder and second control data to the fiber web production line based on first information data received from the slitter-winder and second information data received from the fiber web production line to control the performance of the slitter-winder and the fiber web production line, wherein information data received by the advisor unit comprises data from the group consisting of an operating model of the slitter-winder and an operating model of the fiber web production line based on first principles physical models;
• self-learning systems;
• neural networks;
• learning models;
• artificial intelligence;
• and digital twin-type models.

A system for controlling performance of a slitter winder and a fiber web production line, the system comprising:

• an advisor unit comprising at least one processor and at least one memory unit including computer program code;
• wherein the at least one memory unit and the computer program code are configured, with the at least one processor, to cause the advisor unit to generate and transmit signals comprising first control data to the slitter-winder and second control data to the fiber web production line based on first information data received from the slitter-winder and second information data received from the fiber web production line to control the performance of the slitter-winder and the fiber web production line;
• and
• wherein the advisor is configured to optimize the fiber web production profiles in the fiber web production line so a web tension in a cross-direction and winder set diameter profiles are optimal for the slitter-winder, wherein optimal is the roll diameters of the customer rolls of a set of customer rolls being wound is such that a rider roll in the slitter-winder keeps contact with the customer rolls of the set throughout most of building up of the customer rolls of the set.
