Integrating energy-saving process chains and product data models
The evaluation of energy efficiency in the product life cycle should include the energy used for manufacturing. An early consideration of manufacturing processes during product development can help to optimize the product design in order to achieve an energy-efficient production. Existing approaches and product data management systems lack the integration of energy data for production processes and do not cope with the manufacturing of complex products. Therefore, an integration of energy-saving process chain models with the product structure is proposed in this article. Based on such process chain models, estimations of time, energy and cost for manufacturing parts can be calculated.
