中文摘要：

产品拆解是走可持续发展道路的重要技术环节,可缓解环境压力,最大限度地利用有限资源,提高资源利用率。拆解方案优化对提高拆卸效益至关重要。通过分析产品拆解特点,从技术性、经济性和绿色性3大因素综合考虑影响产品拆解的诸多不确定因素,建立面向绿色设计的拆解方案评价指标体系;运用模糊AHP建立模糊判断矩阵,应用置信度排序法确定合理的指标权重矢量;将灰色系统理论与TOPSIS评估方法相结合,构建一种新的贴近度指标,判定拆解方案的等级及优劣排序;应用实例分析表明,该方法得出的评估结果可靠,且评估过程更具有客观性和准确性。该评估方法的提出,为拆解企业向更合理、更高效的方向发展奠定了理论基础。

英文摘要：

Product disassembly is an important technical link to sustainable development, which can ease the pressure on the environment, utilize the limited resources and improve resource utilization. Optimization of disassembly scheme plays a prominent part in improving the efficiency of disassembly. According to dismantling features, a lot of uncertain factors influencing the product disassembly are taken into account in terms of safety, economy and technology. In addition, evaluation index system of disassembly scheme is built for green design. Build fuzzy judgment matrix via fuzzy AHP, determine reasonable target weight vector using confidence sort, and construct a new closeness indicator combining grey system theory and TOPSIS to determine the sorts of dismantling programs. An example is applied to show that this method is reliable, objective and accurate. The assessment method proposed for dismantling business to a more rational, more efficient direction laid the theoretical foundation.
