Working Area: ICT Platform for Manufacturing

Production companies generate a wealth of data in various areas of the manufacturing processes, which can provide them with valuable insights for optimizing their processes, plants or systems. The effective exploitation of this industrial data requires the use of analytical techniques, including machine learning (ML) algorithms. Various components of an analysis solution must be selected and configured, such as data preparation techniques, IT computing infrastructure and the ML algorithms themselves. A selection of these components based on purely technical information can impair the performance of the resulting analysis solution, since the domain-specific objectives and requirements of the use case have not been explicitly considered.

In this PhD project, domain-specific factors for the selection and configuration of suitable ML algorithms in production are investigated. A framework proposed on the basis of this investigation allows the specification of all components required for an analysis solution. In addition to the data, the IT computing infrastructure and the ML-algorithms, suitable specifications can also be used to define the problem of the analysis solution via domain-specific objectives and requirements. The framework also allows to involve different experts from the respective application domain and from computer science or data sciences in the development process and to structure their cooperation better. Thus, cross-references between the specifications of the problem, data, IT computing infrastructure and ML algorithms can be defined in order to design, implement and validate analysis solutions in a holistic way.
