Abstract
The increased use of recycled and renewable resources is important for achieving sustainable society. The Ministry of Environment in Japan is planning to introduce legislation for promoting recycling of Small size home electrical appliance and exploring efficient collection system by involving recycling industries. The recycling industries face significant uncertainty in quantity of collected Small size home electrical appliance. Some papers and collection experiments point out variation of collection amount and such uncertainties create disincentives for recycling. We propose a recycler model of Small size home electrical appliance with uncertainty in the amount of collection and examine the effect of introducing budget of uncertainty. We showed that the average profit is increased by considering the budget of uncertainty, when the recycler faces large uncertainty. We found that the standard robust optimization approach, that assume the worst case scenario, does not always minimize the risk, there may exist more desirable scenario.
