Prioritizing components for lean and green manufacturing

Más información sobre el libro

In this book, a method is introduced that allows a factory user to evaluate the relevance of components of lean and green manufacturing for his specific factory. Thereby, an efficient and target-oriented improvement of the factory’s cost- and energy-efficiency can be achieved. For this purpose, the method comprises an evaluation process that consists of different steps, including (i) the set-up of a hierarchical factory model and a cost- and energy-extended value stream analysis, (ii) a prioritization of relevant improvement levers of the factory, (iii) a formalization of possibly applicable components of lean and green manufacturing, and (iv) a numerical prioritization of these components based on a criteria matching approach. It is further shown, how the concept was implemented in a prototypical software tool (the “Solution Finder”) and how it was successfully applied at a rail and metro factory of the Siemens AG.
