Method and computer system for determining polymeric product properties

A method for the production of a polymeric product having determined polymeric product properties, comprising:

• providing a prediction model for calculating polymeric product properties based on production parameters on a computer system, the production parameters comprising formulation portions specifying raw material portions for polymeric production and comprising processing parameters specifying process properties during polymeric production,
• providing user input to the computer system, which user input comprises user production parameters specifying a set of production parameters, user product parameters specifying polymeric product properties and a proximity metric for quantifying conformity with the user product parameters,
• applying, by the computer system, the user production parameters to the prediction model to calculate resultant product properties,
• applying, by the computer system, the proximity metric to the resultant product properties with respect to the user product parameters to determine at least one proximity value indicating a match between the user product parameters and the resultant product properties,
• providing, on the computer system, a formulation database comprising test entries for a respective polymeric formulation, wherein each test entry comprises polymeric product properties data associated with that polymeric formulation and comprises formulation portions data specifying raw material portions used for the production of that polymeric formulation and comprises processing parameters data specifying process properties during the production of that polymeric formulation,
• generating the prediction model by executing a numerical analysis program, wherein the set of production parameters comprises at least one properties bracket for a respective process property, which properties bracket defines a subrange within a maximum properties range predefined in the computer system for that process property,
• applying, by the computer system, the user production parameters to the prediction model such that for a plurality of property values within each property bracket resultant product properties are calculated,
• identifying, by the computer system, a recipe for preparing a polymeric product having the calculated resultant product properties, and
• operating a machine in the production of the polymeric product having the calculated resultant product properties according to the recipe.
