Abstract

The identification of platform parameters plays a key role to keep equilibrium between the external diversity and internal commonality. The relationship between the performance parameter and the design parameter in the traditional Quality of House (QoH) was evaluated by a correlation degree rather than an influence degree. The influence degree measures the design parameter’s influence on the performance parameter, and be more effective to evaluate the performance-design relationship. Hence, based on virtual orthogonal experiment, a method incorporated sensitivity analysis into the improved Quality Function Deployment (QFD) is proposed. Firstly, the virtual experiment scheme is designed through the orthogonal experiment table. Secondly, a virtual experiment environment is built by the built-in software, in which the design parameters are assigned with different values and the corresponding performances are monitored in real-time. Then the sensitivity matrix for design parameter is constructed to replace the correlation matrix in the QoH. Thereafter, the improved QFD can be used to identify the platform parameters. A case study for the smartphone of Samsung Galaxy A series is implemented to verify the effectiveness of the proposed method.
通过灵敏度分析和改进的QFD方法进行产品平台规划
平台参数的辨识是保持平台外部多样性与内部通用性平衡的关键。传统的住宅质量评价中,性能参数与设计参数之间的关系是通过关联度而不是影响度来评价的。影响程度衡量的是设计参数对性能参数的影响程度,更有效地评价了性能与设计之间的关系。为此,在虚拟正交试验的基础上,提出了一种将灵敏度分析与改进的质量功能展开(QFD)相结合的方法。首先,通过正交实验表设计虚拟实验方案。其次,利用内置软件构建虚拟实验环境,对设计参数赋值,并对相应性能进行实时监测;然后构造设计参数的灵敏度矩阵代替QoH中的相关矩阵。然后,改进后的QFD可用于识别平台参数。以三星Galaxy A系列智能手机为例,验证了该方法的有效性。
