基于改进型QFD和正交试验混合方法的供应商选择鲁棒性研究

Robust research on supplier selection based on a hybrid method of the improved QFD and orthogonal experimental method

供应商选择问题是供应链优化管理的关键步骤,直接关系到企业的核心竞争力。基于传统制造企业在供应商选择时不能结合供应链中客户需求的现状,通过分析影响供应商选择的评价指标,提出了一种基于改进型QFD和正交试验混合方法的制造企业供应商选择模型,该模型对QFD方法的主要工具———"质量屋"从内容和形式上进行了重构,并利用正交试验设计中的信噪比分析客户需求与各评价指标之间的评分,使被选择的供应商具有令客户满意的鲁棒性能,以此更好地应对供应链中的各种不确定性。最后结合实例进行实证分析,证明此模型实用可行。

The supplier selection is the key to the supply chain management,which are directly related to the key competitiveness of manufacturing enterprise.Based on the actuality that manufacturing supplier evaluation and selection can not combine with the customer demand,a supplier selection model in the manufacturing enterprise based on a hybrid method of the improved QFD and orthogonal experimental method has been proposed.The model reconstructs the main tool of the QFD method — ＂house of quality＂ from the content and form,uses the signal and noise analysis among the orthogonal design method to analyze the score between customer demand and evaluation index system.The model makes the selected supplier working with most robust performance to meet customer satisfaction,and it will be better to deal with the supply chain＇s uncertainties.In the end,the supplier selection model is performed and its validity and feasibility has been verified.
