Information Modeling for Sustainable Manufacturing Assessment

For sustainable manufacturing, energy consumption, air and waste emission, and environmental impact of product and process are analyzed in product and process development. The sustainability assessment is realized based on complete, structured information models of product, process and manufacturing resources, which are proposed in this paper. After analyzing the process of unit assembly and machining, two information models of unit assembly operation and unit machining process are given in UML representation. Besides the basic process parameters, the sustainable manufacturing related information such material consumption, energy usage, wastes and greenhouse air emission are also considered in the models. The manufacturing resource mode is core model to relate process and sustainability indicators. The resource information model of machining tool is proposed with process parameters and unit data of indictors. A sustainability assessment process is given in the end.Copyright © 2014 by ASME
