energy efficiency

During the last decades, automotive manufacturers have outsourced many processes. Hence, complex networks consisting of automotive manufacturers, suppliers and logistics service providers have grown in the automotive industry. The resulting transports of components in these networks often require special load carriers. Consequently, companies nowadays face the challenge to handle a growing number of load carriers. For improving the load carrier management a higher transparency is required regarding the load carriers in the whole network. Transparency can be assured by the application of radio frequency identification technology. However, especially logistics service providers have to invest in this technology, which can be implemented in different ways. In this paper, some application possibilities are described and analyzed regarding economic and energy efficiency.

The energy used in production moves more and more into the focus of optimization efforts. It is important to consider the processes in production. The energy value stream mapping method is to bridge the gap between the value stream mapping optimization of material flow with the use of resources and energy demand. Under the expert guidance the production is shown in a snapshot. With the help of defined types of waste and design guidelines the production is quickly been analyzed and optimized. Results are numerous measures that can often be realized easily and with little effort. Energy savings of 10,000 EUR and more are opened up so quickly.

In many industries the success of companies depends on efficient and sustainable processes: In which way higher output can be achieved by less resource consumption? Many process optimization projects improve single processes but not the whole process chain. Thus a high amount of potentials of resource efficiency are unutilized in manufacturing. For realising enormous achievements energy and resource efficiency have to be integrated into the optimization process.

The article presents an approach for the integration of the energy efficiency in factory planning processes. The main focus is not on the constructional hull but rather on the energy-efficient designing of production processes and production plants. The approach is of general validity but in the present example it is applied to the automotive industry. Main contents of the approach are aimed at the life cycle consideration of production plants.
