Ecological sustainability in production does not only cause a positive contribution to environmentalism, but also leads to a longterm improvement of the companies’ competitiveness. Due to a lack of transparency, many companies face difficulties rating their own resource efficiency. This article deals with the introduction of a ratio system, which allows companies to evaluate the efficiency concerning their usage of resources. This enables companies to enhance their consumption transparency. Besides, this article discusses the challenges of using ratio systems and the comparison of ratios in general.

The potentials of a resource efficient production become the focal point of interest of production companies. Necessary for a permanent change are qualified and motivated employees. This article describes the requirements for the change such as a fundamental shift in values and a position specific qualification. Furthermore, relevant steps for establishing an efficient working organisation are presented.

These days, competitive advantages for manufacturing companies can not be achieved by a detached configuration of specific processes but only within an inte-grative configuration of the complete system factory. The deployed technologies and the manufactured products have a significant influence on the configuration of a factory. To allow a better coordination between technology, product and factory planning, an approach for integrated factory coordination has been developed at the Hannover Centre for Production Techno-logy (PZH). This approach is based on the general roadmapping idea and allows the systematisation of the information transfer concerning content and time between factory, technology and product planning.

The development of changeable factory concepts influences the site competitiveness of producing companies. The impact of the underlying factory structure, the factory layout, and the logistics on the operating efficiency of a factory concept is unquestioned. The influence of future production technologies or products on the factory concept, however, is often neglected. In a cooperative project a new method has been derived which allows a holistic coordination of all three elements factory, technology and product.
