在持续进步的制造技术环境和复杂多变的市场环境下,以渐进创新为目标的复杂产品设计变更活动高频多发。为有效预测受变更传播影响的生产制造成本,提高设计变更决策的效益性和准确性,从企业内部价值链视角出发,提出基于复杂网络方法的变更成本预测模型。基于负载容量模型对变更传播进行表达,构建设计特征变更传播分析模型;采用改进的灰色关联度、关联分析方法对全局权重进行计算;基于变更传播影响下的量化设计特征值,建立基于特征映射的变更成本预测模型。最后,以G公司某型永磁同步变频冷水机组为案例,验证了所提方法的可行性和有效性。

经典DEA交叉效率评价方法为了追求评价结果的客观性,往往忽略了决策者在评价过程中的主观性,从而导致主观决策信息的丢失,使得评价结果有效性较弱。针对这一问题,本文将决策者的主观心理偏好纳入研究中,提出一种结合数据包络分析和有序加权平均算子的心理偏好结构交叉效率评价方法。利用该方法,首先,采用对抗型数据包络分析模型求得决策单元的初始交叉效率矩阵;其次,使用偏度和标准差测量出决策者在对决策单元进行评价时所产生的心理偏好结构,即偏好优先级与偏好差距,并修正初始交叉效率矩阵;随后,基于最小偏好差异最大化的思想对决策单元进行偏好权重分配,同时结合有序加权平均算子对交叉效率评价信息进行集结,得出决策单元最终交叉效率值。本文所提方法不仅充分考虑了决策者的主观心理偏好,而且最大程度地利用了原始数据信息,减少了评价信息的丢失,提高了评价结果的合理性和有效性。
