Abstract
Due to the rising awareness of environmental protection, green product markets have grown rapidly. To comply with environmental regulations and increase larger market shares, many enterprises greener their products’ designs. However, most green product designs primarily focus on the recyclability of products instead of the carbon emission resulting from manufacturing and their associated supply chain activities. To solve the problem, from the viewpoint of the comprehensive carbon emission, we propose a model consisting of a leader (the product designer) and a follower (the manufacturer) and utilize Dynamic Programming (DP) to solve it. To calculate carbon emission efficiently, we adopt the life-cycle assessment (LCA) which is a practical technique to measure carbon emission in the entire products’ life cycle from cradle to gate. In the proposed model, the product designer provides the information of the product designs and the carbon rebates which can induce the manufacturer to reduce carbon emission and satisfy the carbon emission requirements. The manufacturer configures a production chain after learning of the information of the product design and the carbon rebate announced by the product designer. The mechanism of carbon rebate enables the product designer to induce the manufacturer to select a more eco-friendly supply chain configuration with less carbon emission. A real world table lamp example is used to illustrate the proposed method. We propose a decision-making system supporting the product designer to select the product design and the manufacturer to select its optimal supply chain configurations. The result of the case study shows that the product designer can find out an optimal set of decisions to produce.
