Abstract: This paper studies the decision-making problem about the collection and remanufacturing of elect tronic product manufacturers. A premium and penalty mechanism is designed to drive the manufacturer to collection and remanufacturing.Three decision-making models are established and the results of these models are comparedl Several conclusions are shown. The manufacturer is willing to collect and remanufacture waste products only when he has the advantage of cost. Collection rate increases, new product price decreases and new product demand increases with the premium and penalty mechanism if the manufacturer has the advantage of costl Collection rate increases, new product price increases and new product demand decreases with the premium and penalty mechanism if the manufacturer has not the advantage of cost. Critical points about having and not having the cost advantage are derived for the profits with the premium and penalty mechanism or not independently.The conclusions can benefit the government for guiding the COLA lection and remanufacturing of manufacturers.

Key words: reverse logistics, premium and penalty mechanism, collection, remanufacturing
