The present disclosure relates to a method for determining at least one process variable of a medium. The method includes steps of recording a first value for the process variable by means of a first method for determining the process variable and recording a second value for the process variable by means of a second method for determining the process variable. The method also includes steps of selecting at least one of the detected values for the process variable by means of a classifier and outputting the selected value for the process variable. The present disclosure further relates to a computer program designed for executing a method according to the present disclosure, and to a computer program product having a computer program according to the present disclosure.

A method, system and computer-readable storage medium for estimating an ecological impact of textile fabric production are provided. The ecological impact comprises a natural environmental impact. The method comprises: inputting composition of a textile fabric and a name of region where one or more steps of the textile fabric production are implemented; calling corresponding data from a database according to the input composition and the input name of region; and obtaining a score of the natural environment impact for the one or more steps of the textile fabric production according to a predetermined first operational rule and the data.
