Increasing resource efficiency with an engineering decision support system for comparison of product design variants

2019 , Buchert, Tom , Ko, Nathanael , Graf, Roberta , Vollmer, Thomas , Alkhayat, Moritz , Brandenburg, Elisabeth , Stark, Rainer , Klocke, Fritz , Leistner, Philip , Schleifenbaum, Johannes Henrich

The development of sustainable and resource-efficient products requires consideration of multiple design targets concerning the whole product life cycle. Taking these factors into account leads to complex decision situations with conflicting targets and trade-offs. To support design engineers in these situations an Engineering Decision Support System (EDSS) has been developed. In this article, the overall concept of the EDSS is presented. Furthermore, one function of the EDSS to assist a systematic comparison of product variants is introduced in detail. It is based on combining an existing PLM solutions (in particular Siemens Teamcenter 11/Siemens NX9) and software for Life Cycle Assessment (GaBi 7). Beyond a proof of concept for information exchange between both systems a methodology is presented which enables design engineers to systematically assess and select multiple product variants based on their resource utilization. The approach is complemented with a comprehensive case study for different design options of a core slide. In the scope of this study, variations of geometry (solid vs. hollow design), materials (hot-working steel vs. nickel-based superalloy) and manufacturing processes (laser metal deposition vs. milling) were considered. Furthermore, a usability study of the decision support tool is shown.

Systematic integration of design-for- recycling into product design

1995 , Kriwet, A. , Zussmann, E. , Seliger, G.

This paper presents an approach for incorporating recycling considerations into product design. The approach regards the recycling aspects of product design, different recycling processes and the product logistic support during the end-of-life stage. The concept of a recycling network is introduced which consists of the designer, consumers, recyclers and suppliers, allowing the effective exchange of information and handshaking for cooperation. Guidelines dedicated to design-for-recycling are presented to assist the designer to develop a recycling friendly product reflecting the objectives of all network partners. The approach is demonstrated by investigating current industrial product recyclability features and further improving them by applying design-for-recycling guidelines.

Betrieblichen Umweltschutz überprüfen

1994 , Butterbrodt, D. , Tammler, U.

Ab April 1995 wird mit der Europa-Verordnung 1836 ein wirksames Umweltmanagement-System auf freiwilliger Basis geschaffen. An der Umweltbetriebsführung führt bald kein Weg mehr vorbei: Schon jetzt lassen die gesellschaftlichen und technisch-organisatorischen Rahmenbedingungen ein systematisches Kontrollverfahren zur Überprüfung der umweltrelevanten Betriebsvorgänge ratsam erscheinen. Ab April 1995 wird mit der EU-Verordnung 1836 der Druck auf die Firmen verstärkt. Dipl.Ing. Detlef Butterbrodt und Ulrich Tammler beschreiben, was beim Aufbau eines Umweltmanagement-Systems zu beachten ist.
