Quantitative Factory Lifecycle Evaluation (Qfalle)
Final Report Abstract
In the project "Quantitative Fabrik-Lebenszyklus-Evaluation” (Quantitative Factory Life Cycle Evaluation - Qfalle) a life cycle-oriented understanding of factory systems was developed. For this purpose, descriptive models of the factory life cycle were generated, which formed the basis for the derivation of qualitative impact models and subsequently enabled the creation of analytical models of factory objects and the factory system. A dynamic factory life cycle model combines the individual models of the factory objects and allows the scenario-based evaluation of different factory configurations. Qualitatively described factory objects, associated system variables and change drivers as well as an indicator system are the relevant components of the description model. The evaluation and knowledge generation are supported by prototypically implemented, interactive visualisations. As a result of the project "Qfalle", an overall model for the quantitative life cycle evaluation of factories ("LC factory model") is available, which has been evaluated through concrete use cases. The model offers factory planners a suitable tool to evaluate the economic and ecological objectives of an entire factory over its life cycle. Based on this, different factory configurations can be analysed with relevant economic and ecological evaluation criteria. The developed models and visualisations were subjected to plausibility tests and sensitivity analyses, in which the model response and reliability of the forecasts were successfully verified. The contributions of the "Qfalle" project expaned the existing knowledge and the available methods in the field of factory planning. Based on the results of the research project, factory planning tasks can integrate economic and ecological target variables while taking the heterogeneous life cycles of the factory objects into account, in order to cope with various drivers of change.
