description A method and apparatus for controlling the drying process taking place in the dryer section of a paper machine or the like. The total drying efficiency required in the dryer section is first calculated by means of a method known as such, and an optimal drying efficiency distribution is compiled. Using the optimal drying efficiency distribution, the dryer section is divided into two or more imaginary drying segments which differ in their drying action, in at least one of which segments there are at least two dryer units using different forms of energy and/or at least two separately adjustable dryer units using the same form of energy. The total drying efficiency obtained is divided, by means of an optimization method known as such, between the said different drying segments in such a way that a good drying efficiency distribution is achieved in terms of the quality of the web being dried.
