服务型制造网络模块化质量属性识别

Modular quality attributes recognition of service-oriented manufacturing network

针对服务型制造网络(SMN)质量属性多级协同交互及各自相关矩阵非对称性问题,采用质量功能展开(QFD)将顾客需求映射到SMN模块化多级质量属性设计过程中,提出一种结合模糊层次分析(FAHP)、决策试验与实验评估(DEMATEL)的多模块递阶质量屋方法来计算考虑非对称性自相关矩阵的质量属性权重。首先从质量特性、质量水平、质量行为3个维度构建SMN模块化质量属性评价指标,然后建立FAHP-DEMATEL多模块递阶质量屋模型计算SMN模块化质量属性权重,并根据权重识别关键质量属性。最后通过案例对比传统QFD和FAHP-QFD方法,验证所提方法能够更好地揭示模块化间的协同交互规律及各自内部因素的直接关系与间接关系。

To address the problem of multi-level collaborative interaction of quality attributes and asymmetry of their respective correlation matrices in Service-oriented Manufacturing Networks(SMNs).The Quality Function Deployment(QFD)was employed to map customer requirement into the design process of SMN modular multi-level quality attributes.A multi-module recursive quality house method combining Fuzzy Analytic Hierarchy Process(FAHP)and Decision Making Trial and Evaluation Laboratory(DEMATEL)was proposed to calculate quality attribute weights considering asymmetric autocorrelation matrices.The SMN modular quality attribute indicators were constructed from three dimensions of quality characteristic,quality ability and quality behavior.Then,the FAHP-DEMATEL multi-module hierarchical house of quality model was established to calculate the quality attributes weight of the SMN modularization,and the key quality attributes were identified according to the weights.The practical application was given to compare with the traditional QFD and FAHP-QFD identification methods,from which we found that the proposed method could reveal the law of collaborative interaction among multiple modules,and the direct and indirect relationships between their internal factors better.
