在简要介绍“技术成熟度”基本概念的基础上,以美国国防采办项目为例分析了国外技术成熟度评价组织结构的层次关系,总结了“技术成熟度”评估的一般流程,进而应用熵权理论对复杂装备研制过程技术成熟度进行了评价,并在理论研究的基础上应用于某型号飞机制造的实例中。 Based on the brief introduction of the basic concepts of “technology maturity”, taking the US defense acquisition project as an example, this paper analyzes the hierarchy of the evaluation of the organizational structure of foreign technology maturity and summarizes the general process of “technology maturity” Then the entropy weight theory is applied to evaluate the technology maturity of the complex equipment development process. Based on the theoretical research, this method is applied to the manufacture of a certain type of aircraft.
