针对基于灰靶理论的技术贡献度算法的缺点,提出一种基于定量和定性分析相结合的改进算法,计算航天型号工程关键技术贡献值(Technology Contribution Value,TCV)。首先,根据航天型号工程关键技术的设计要求计算靶心度,解决了任选同类系统作为参考体系给技术贡献度计算带来的不确定影响。然后,结合对关键技术的定性分析,进一步提高定量计算技术贡献度的准确性,使得最终计算的结果能够客观地反应各项关键技术在航天型号工程中的重要程度。该方法可用于航天装备体系的技术发展规划,为航天装备体系的发展决策和研制提供技术支持。
Aiming at the shortcomings of the algorithm based on gray target theory, an improved algorithm based on quantitative and qualitative analysis is proposed to calculate the key technical contribution (TCV) of aerospace engineering. First of all, based on the design requirements of the key technologies of aerospace engineering, the target center of gravity is calculated and the uncertainties caused by the calculation of technical contribution are solved by using the same system as the reference system. Then, combined with the qualitative analysis of the key technologies, the accuracy of the contribution of the quantitative calculation techniques is further improved so that the final calculation results objectively reflect the importance of each key technology in the aerospace engineering. The method can be used in the technical development plan of the spaceflight equipment system and provide technical support for the development decision-making and development of the spaceflight equipment system.
