摘要:
The invention relates to a method in the manufacture of a fiber-based web-like product for optimizing the operation of the process being used, in which method quality factors are defined for the product being manufactured control variables, which affect the state of the process, or quality factors of the finished product, are defined for at least part of the process. In addition, an operating model is created, which is used to depict the effect of each control variable on the quality factors, and a user interface is created, through which varying values for the control variables can be input to the operating model and the values of the quality factors can be depicted simultaneously, in such a way that the values of the control variables and the values of the quality factors can be viewed simultaneously.
摘要:
A method and a system for controlling the manufacturing or finishing process of a fiber web at a transition stage of the process. In the method a corrected error profile (PD′k) is formed using an error profile (PD). Using the corrected error profile (PD′k) at least one control signal (CAk) is determined for the actuators (6) of the manufacturing or finishing process of a fiber web.
