“…Most of the graphical techniques (AND/OR graphs, IDEF models, Petri Nets, etc.) are used to examine disassembly levelling and sequencing problems (Dong & Arndt, 2003;Duta, Filip, & Henrioud, 2002;Fernandez & Zerhouni, 2001;Jehng, Peng, & Zhou, 2002;Kumar Singh, Tiwari, & Mukhopadhyay, 2003;Li, Khoo, & Tor, 2002;Tang, Zhou, & Caudill, 2000;Xirouchakis & Kiritsis, 1997). Zussman and Zhou (1999) recognise the uncertainties involved during the disassembly process and propose a Petri Net (Murata, 1989) based methodology for adaptive disassembly planning.…”
