Precise sustainability assessment becomes increasingly important in decision-making, marketing, and regulations. Therefore, reliable and comparable LCA becomes mandatory. Currently, primary data is rarely available due to vastly complex value chains. Secondary data from eco-databases provide a remedy to estimate the sustainability impacts of up- and downstream processes. While giving insights and estimations, this data is seldom fitting exactly to the own processes and lacks comparability. Therefore, this paper proposes a method to close the gap between unreliable secondary data and unavailable primary data. This gap is to be closed by the integration of simulated process data. CAM is a tool during the work preparation to assess the design's manufacturability, decrease set-up times and optimize the NC code. However, integrating DES into LCA is still subject to research and will be discussed in this paper. This paper answers the question of the necessary steps to integrate the simulated production process in an LCA to increase the quality and reliability of sustainability indicators. A method is presented, and the implementation of the steps with the help of a developed assistance system on an example is performed.

“…In [16], Sheng decomposes the environmental impact component into "micro" analyses of individual features [19] and "macro" analyses of feature interactions [20]. To evaluate the resources and environment attributes of the manufacturing process, Zhang H. et al [21] present an input-process-output (IPO) model and an evaluation index system in order to select the greenest process plan.…”

Environmentally conscious manufacturing process (ECMP) has become an obligation to the environment and to the society itself, enforced primarily by governmental regulations and customer perspective on environmental issues. ECMP involves integrating environmental thinking into new product development. This is especially true in the computeraided design (CAD) phase which is the last phase in the design process. At this stage, more than 80 % of choices are done. Feature technology (FT), the core of the CAD phase, is then used to integrate environmental aspects. Also, integrations realized on CAD systems, such as computer-aided manufacturing (CAM), computer-aided process plan (CAPP), and product life management (PLM), are explored to ecodesign products. This paper presents a new methodology for the selection of a green manufacturing process based on CAD features and CAD/CAM/CAPP/PLM integrations. Firstly, we present an overview of works using FT in the CAD phase to reduce the environmental impacts of a manufacturing process. Secondly, we propose an approach based on FT for selecting an ECMP to promote a new simple eco-design tool which helps inexperienced eco-designers. Finally, a case study is considered to validate the proposed approach and results are commented.

To evaluate the resources and environment attributes of a/manufacturing process, Zhang et al [42] present an InputProcess-Output (IPO) model and an evaluation index system based on a scatter degree combination evaluation method to solve the inconsistency produced by different evaluation methods in order to select the greenest process plan. This task presents the core of several works.…”

The integration of environmental aspects in design frameworks has become a necessity for manufacturers to maintain their market position. This is especially true in the Computer Aided Design (CAD) phase, which is the last phase in the design process. At this stage, more than 80% of choices have been made. However, the environmental impacts generated by the remaining choices are significant. Features Technology (FT), the core of the CAD phase, is used to integrate environmental aspects. This paper presents a literature review of different works based on FT to ecodesign products. First, we present an overview of features in CAD systems. Second, we present a critical review of works done on ecodesigning with features that we divide into two subsections: the first one concerns CAD-Life Cycle Assessment (LCA) integration (methodologies, prototype tools, and commercial tools), and the second one, works using FT in CAD phase to reduce the environmental impact of one life cycle stage such as material selection or manufacturing. Finally, we propose an approach based on FT for ecodesigning products to promote simple new ecodesign tools which will help the inexperienced designer.
