ABSTRACT As one of the most important components of machine tool, guideway has an important driving force to comprehensively improve the remanufacturability of machine tools. To select optimal guideway for machine tool remanufacturing, an integrated multi-criteria decision-making (MCDM) approach that combines improved analytic hierarchy process (AHP) and connection degree-based technique of ranking preferences by similarity to the ideal solution (CD-TOPSIS) method is proposed. The improved AHP is employed to calculate the weights of each criterion and the CD-TOPSIS is adapted to complete the task of sorting; finally, the comprehensive evaluation of the alternatives is carried out. A case study, i.e. eight types of guideways, is illustrated to verify the proposed MCDM method. In addition, comparison with existing methods is performed to validate the effective and reliability for the proposed hybrid approach. Also, sensitivity analysis is provided to evaluate the robustness of the method. The final result shows the method provides reliable decision support for the selection of machine tool guideways for remanufacturing.

考虑再制造性的机床导轨选择综合决策方法

摘要 作为机床最重要的部件之一，导轨对全面提高机床的再制造性具有重要的推动作用。为了选择机床再制造的最佳导轨，一种综合多标准决策（MCDM）方法，它结合了改进的层次分析法（AHP）和基于连接度的基于与理想解决方案相似度的偏好排序技术（CD-TOPSIS）方法提出。采用改进的层次分析法计算每个准则的权重，采用CD-TOPSIS完成排序任务；最后，对备选方案进行综合评价。一个案例研究，即八种类型的导轨，被说明以验证所提出的 MCDM 方法。此外，与现有方法进行比较以验证所提出的混合方法的有效性和可靠性。此外，还提供了敏感性分析来评估该方法的稳健性。最终结果表明，该方法为再制造机床导轨的选择提供了可靠的决策支持。
