Abstract
Properties of an end product, such as paper, paperboard or board, are important for the user of the end product. To be able to manufacture an end product of desired quality, it is important to know what kind of paper pulp used for manufacturing the end product results in a particular kind of property of the end product. Embodiments provide a method and an apparatus for generating a model, which model connects at least one property of the end product with at least one property of the paper pulp. On the basis of the model, also the manufacturing process can be controlled.

A method, comprising
- taking a sample from liquid fibre pulp used for manufacturing the end product;
- determining at least one property of the sample at a moment of time T1;
- determining at least one property of the end product at a moment of time T2 which is later than the moment of time T1;
- generating a model based on the determined at least one property of the end product and at least one property of the sample;
- taking a sample from the liquid fibre pulp used for manufacturing the end product;
- determining at least one property of the sample at a moment of time T3 which is later than the moment of time T2;
- and
- modelling, at a moment of time T4 which is later than the moment of time T3, the at least one property of the end product on the basis of the generated model when at least one property of the sample is known.
An apparatus, comprising a processor arranged to:
- receive information on at least one determined property of a sample of liquid fibre pulp, which is used for manufacturing the end product at a moment of time T1;
- receive information on at least one determined property of the end product at a moment of time T2 which is later than the moment of time T1;
- generate a model based on the determined at least one property of the end product and at least one property of the sample;
- receive information on at least one determined property of the sample of the liquid fibre pulp, which is used for manufacturing the end product at a moment of time T3 which is later than the moment of time T2;
- and
- modelling, at a moment of time T4 which is later than the moment of time T3, the at least one property of the end product on the basis of the generated model when at least one property of the sample is known.
A method, comprising:
- receiving information on at least one property of the end product;
- and
- acquiring information on a model which has been generated on the basis of at least one property of liquid fibre pulp and at least one property determined from the end product, and which connects the at least one property of the end product with the at least one property of the liquid fibre pulp used in manufacturing the end product;
- and
- controlling, on the basis of the model, the at least one property of the liquid fibre pulp to be such that it produces at least one desired property of the end product.
An apparatus, comprising a controller arranged to:
- receive information on at least one desired property of the end product;
- and
- acquire information on a model which has been generated on the basis of at least one property of liquid fibre pulp and at least one property determined from the end product, and which connects the at least one property of the end product with the at least one property of the liquid fibre pulp used in manufacturing the end product;
- and
- control, on the basis of the model, the at least one property of the liquid fibre pulp to be such that it produces at least one desired property of the end product.
