Evaluation Model for Product Green Design Based on Active Remanufacturing

In order to optimize product design, to improve product manufacturability, to resolve the status of current production's passive remanufacturing, this paper proposed the concept of active remanufacturing design oriented to product green design. The improved model of active remanufacturing product design was established and divided into four stages which are product remanufacturability analysis, optimization design, design parameter feedback and remanufacturability evaluation. Through the establishment of product design green system analysis and evaluation model, a design thought was proposed to evaluated design scheme comprehensively and select a preferable remanufacturing of green products. Finally, the model's validity and practicability are validated by the example of a new design of NC machine tool.
