基于质量屋的LED路灯关键质量特征研究

以LED路灯质量性能特征为研究对象,在对用户需求进行调查、分析和整理的基础上,建立用户需求与质量特征关系矩阵和质量规划矩阵,利用质量功能展开(QFD)软件建立LED路灯质量屋(HOQ),将质量屋相关信息输入质量屋中,获得质量屋输出的产品质量特征的绝对重要度和相对重要度,从而实现由用户需求向产品质量特征的转换,根据不同的用户需求,选取不同的质量特征相对重要度阈值,最后获得用户满意的LED路灯关键质量性能特征集。该研究为产品开发和产品标准化建设提供科学参考。

Research on Key Quality Characteristics of LED Street Lamps Based on House of Quality

Taking quality performance characteristics of the LED street lamp as the research object,this paper built the relationship matrix of user requirements with quality characteristic and the matrix of quality planning based on user requirements investigation and analysis. Quality function deployment（ QFD） software was used to establish house of quality（ HOQ） of the LED street lamp. With the information input for house of quality,the absolutely important degree and the relative important degree of the product quality characteristics were outputted by house of quality,so as to realize conversion from user requirements to product quality characteristics. According to different user requirements,to select the different threshold value of relative important degree of the quality characteristics,finally the key feature set of quality performance for the user satisfaction of LED street lamp was obtained. As a result,the scientific evidence for decision-making could be attained for the development and standardization construction of this product.
