Customer demands have diversified and manifest themselves in a greater diversity of variants. Handling the growing number of product and process variants is getting more and more difficult and often results in errors and high additional expenses. Moreover, environmental aspects as minimal CO2 emissions are becoming increasingly important for manufacturing companies nowadays. Due to a high complexity it is very hard for manufacturing companies to predict the effects of a greater variant diversity in production, especially for environmental issues.
This paper presents a procedure for assessing environmental effects of variety-induced complexity in production systems. Therefore an assessment model has been developed, which allows measuring environmental effects caused by variety-induced complexity. Based on this, performance indicators are generated in order to evaluate the eco-efficiency of a specific production system. The presented approach is tested in a case example.
