Abstract: | The current revival and intensified research on machine learning take place while an intensified focus of companies on digitalization developed. The willingness and acceptance to apply innovative methods in industry has grown. Gray box or hybrid process modeling represents the combination of rigorous (white box) process modeling with machine learning (black box) models. In recent applications, the presented method has been utilized for process models at Evonik. This article describes the workflow for developing hybrid process models and is meant to share the experiences made during the process. |
