It is estimated that, on average, 60-70% of the costs of manufactured goods come from raw materials and purchased components Har92]. As industry moves toward an increasingly more global market economy in which companies focus more on the production of core high-value-adding components, this gure can only increase.

The manufacturers produce a homogenous product for a set of customer markets. The product can be comprised of both virgin materials and recycled materials obtained from used products returned by the customers. Society is modelled as an additional player whose objective ...
