Application of system dynamics to assess mass flows of waste electrical and electronic equipment (WEEE)


Sinha Khetrival, Deepali; Widmer, Rolf; Schwaninger, Markus; Hilty, Lorenz (2012). Application of system dynamics to assess mass flows of waste electrical and electronic equipment (WEEE). In: The 30th International Conference of the System Dynamics Society, St. Gallen, 22 July 2012 - 26 July 2012.

Abstract

The consumption and disposal of electrical and electronic equipment forms a dynamic sys-tem. This paper applies system dynamics methodology to assess mass flows of end-of-life equipment. In the paper, two modelling approaches to forecasting disposal of consumer dura-bles are discussed, namely the “delay model” approach and the “reverse diffusion model” ap-proach. Applying the same dataset on the disposal of cathode ray tube personal computer monitors in Switzerland to both the approaches, the estimates and forecasts of the models are compared against real system data. The comparison provides an opportunity to discuss fur-ther improvements to both modelling approaches.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
