Abstract
Closed-loop manufacturing systems (CLMS), where products are made from used products, reused parts and materials from market, as well as new ones, has gained researchers' interest in recent years due to growing concern about environmental problems. In order to operate and control CLMS effectively, quick and adequate matching of demand and supply of recovered materials is indispensable. This paper proposes a multi agent algorithm for matching supply and demand of recovered components considering various fluctuations in user preference and physical conditions of recovered components. Effectiveness and feasibility of our method are demonstrated by a simplified simulation of CLMS for laptop computers.
