Abstract: To reduce the damage of remanufacturing cost disruption on manufacturer competitive closed-loop supply chain,the optimal production decisions in closed-loop supply chains consisted of two competing manufacturers and one retailer with remanufacturing costs disruptions was researched under the background that three types of remanufacturing costs disruptions scenarios which was manufacturer himself disruptions,competitor disruptions and double disruptions.The results indicated that the pricing and production quantity decisions under three types of remanufacturing costs disruptions scenarios,and the return rate decision with competitor disruptions had certain robustness,while the return rate decision with manufacturer himself or double disruptions always changed.The profits of manufacturer under himself or double disruptions scenarios,and the profits of retailer under three disruptions scenarios were decreased with disruptions,while the profit of manufacturer under competitor disruption scenario was increased with disruptions.The influence of one manufacturer with disruptions on production quantity and the profit of manufacturer was the most,while the influence of double disruptions on price,return rate and the profit of retailer was the most.The greater the competition between manufacturers,the smaller the robustness region.

Key words: closed-loop supply chain, competition, remanufacturing cost disruptions, production decisions
