Analyses, simulations and assessments of the sustainability of products or their manufacturing both within companies and across life cycles and value networks are our focus. The technical approach is supported by sustainable business models such as platform concepts, digital marketplaces and partnership models. Accordingly, the research group has an interdisciplinary orientation and thinks beyond the challenges of classical production.
SMS offers strategic approaches that harmonize well with the other groups of the R&D area Production and also with research groups from other OFFIS areas, as the same technologies (for example artificial intelligence, digital twins or data platforms) are used. On this basis, the group develops analysis methods and technologies that serve to better understand and guide resource requirements and thus reduce resource consumption.
In general, SMS investigates and optimizes sustainability aspects of production processes with a special focus on resource requirements (raw materials, energy consumption in operation and in the upstream and downstream processes of a product - the so-called gray energy, and emissions). The digitalization of industrial production and new value networks can help to make energy and resource consumption more efficient over the entire product life cycle. The assessment framework of the investigations can therefore include a single company (for example, within a company from "gate to gate" taking into account the process chains) or the entire value chain with the participation of other companies involved. The aim of the group is to help companies reduce their material and energy consumption in the long term so that they can remain competitive in the market and shape the transformation to digitalization as sustainably as possible.
Focus of the Group:
- Resilient supply chains in production
- Supervision and monitoring of critical or strategic economic resources
- Circular economy
- Efficient resource, material and energy consumption
- IT for Green (optimizing resource requirements through digitalization)
- Green IT (preventing IT from consuming more resources than it saves)
- Technology impact assessment
