Device and method, in particular a computer-implemented method, for determining the effect of characteristics of an object, in particular of a workpiece, on a result of an operation of a technical system for influencing the characteristics, in particular of a production line

A computer-implemented method for determining an effect of characteristics of an object, including a workpiece, on a result of an operation of a technical system for influencing characteristics of a production line, the method comprising the following steps:

• providing measured values for the object measured on the object;
• providing a data set includes measured values provided for other objects, wherein each of the measured values quantify a characteristics of a respective object of the object and the other objects;
• determining, depending on the measured values for the object and for the other objects, graphs which characterize a causal relationship between the characteristics of the respective objects;
• determining, for each of the graphs, depending on the measured values and depending on the graphs, an estimation rule for estimating effects of the characteristics, whose causal relationship is characterized by the graph, on each other;
• for each respective characteristic of at least one subset of the characteristics, determining a prediction of effects, on the respective characteristic, of the other characteristics from the subset, using a model for predicting the effects of the other characteristics from the subset on the respective characteristic, depending on the estimation rule for the graphs which characterize the causal relationship between the characteristics from the subset;
• and
• quantifying, for at least one characteristic from the subset, the effect of the other characteristics depending on the predictions determined with the model for the at least one characteristic.
