航空发动机客户需求与技术措施重要度量化评估应用研究

现有的民用航空发动机客户需求重要度的量化评估方法不符合民用航空发展稳中求进的需要。采用Kano 模型和质量功能展开（QFD）方法，提出一种客户需求技术措施重要度量化评估改进算法与技术措施重要度量化评估方法，增加客户需求重要度调整系数中基本型需求的比重，将客户需求进行重要度量化评估并转化为可量化的发动机产品和服务的技术措施，完成技术措施的优先级排序；给出民用航空发动机运行支持体系、换发设备开发的应用案例。结果表明：客户需求重要度量化评估改进算法与技术措施重要度量化评估方法能够在发动机产品和服务研制过程中更加科学有效地进行资源分配与决策，提升产品市场竞争力。

Application Research on Quantitative Evaluation of Engine Customer Demand Importance and Technical Measure Importance

At present, the quantitative evaluation method of the importance of civil aviation engine customer demand proposed by many scholars at home and abroad does not meet the needs of civil aviation development. Using Kano model and QFD method, this paper proposes an improved algorithm for quantitative evaluation of the importance of customer demand and technical measures, increases the proportion of basic demand in the adjustment coefficient of the importance of customer demand, quantitatively evaluates the importance of customer demand and converts it into quantifiable technical measures for engine products and services, and completes the priority ranking of technical measures.This paper presents the application cases of civil aviation engine operation support system and replacement equipment development. The results show that the improved algorithm for quantifying the importance of customer needs and technical measures can make more scientific and effective resource allocation and decision-making in the process of engine product and service development, and enhance the market competitiveness of products.
