Abstract
For the prognosis of a value of a characteristic of a product which is to be produced with the aid of a neuronal network, the history of the product is taken into account when determining an input variable of an input neuron of the neuronal network.

1-13. (canceled)
A production method for predicting, using a first neuronal network, a value of a property of a product to be produced, comprising:
- subjecting a production process of the product to a non-linear dynamic;
- measuring values of the property of the product as produced at different times;
- predicting in a preliminary prognosis a preliminary value of the property of the product to be produced;
- determining an input variable for an input neuron of the first neuronal network, taking into account the preliminary value;
- and
- predicting the value of the property of the product to be produced in a subsequent prognosis using the first neuronal network, where the first neuronal network includes a non-linear part.

A system for predicting a value of a property of a product to be produced, comprising:
- means for subjecting a production process of the product to a non-linear dynamic;
- means for measuring values of the property of the product as produced at different times;
- means for predicting in a preliminary prognosis a preliminary value of the property of the product to be produced;
- means for determining an input variable taking into account the preliminary value;
- and
- a neuronal network, having a non-linear part and an input neuron receiving the input variable, predicting the value of the property of the product to be produced in a subsequent prognosis.
