State of Research

This chapter provides an overview of the state of research in the field of planning of eco-efficient production systems. At first, based on the findings of the preceding chapter, the research scope is defined and the research question is derived. Then, the classification system for literature evaluation is described as well as the derivation of evaluation criteria. In the following, the adjacent fields of research are delimitated before the core research approaches are presented and evaluated in detail. On this basis, the findings and research demand are derived.
