Disassembly modeling: two applications to a Philips 21" television set

Disassembly modeling is an important issue in environmentally conscious design. Two approaches to disassembly modeling are described in this paper. The first estimates disassembly times by applying work-measurement analyses to disassembly tasks. The second approach uses measurements of actual dismantling processes to predict the disassembly time of similar products. Both approaches are applied to a Philips television set. It is shown that, although substantial differences exist between both approaches, similar results can be derived from both models for the case study. The paper concludes by discussing the applicability of both models
