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

Application research on quantitative evaluation of engine customer demand and technical measure importance

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。

The available quantitative evaluation method of the importance of civil aviation engine customer demand cannot meet the needs of civil aviation development.Kano model and quality function deployment(QFD)method are used to propose an improved importance quantitative evaluation algorithm of the customer demand and a importance quantitative evaluation method of technical measures,in which the proportion of basic demand in the adjustment coefficient of the customer demand importance is increased,and the importance quantitative evaluation of customer demand is converted into quantifiable technical measures for engine products and services,and the priority ranking of technical measures is completed.The application cases of civil aviation engine operation support system and replacement equipment development are given.The results show that the improved importance quantitative evaluation algorithm of the customer demand and importance quantitative evaluation method of 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.
