摘要:

针对高超声速飞行器研制工程的高风险特点,对工程决策方和研制方面临的不同类型风险进行了建模分析。基于系统方案或关键技术的固有风险概率和抽象化的研发与验证过程,分别计算分析了工程决策方误判验收通过不合格产品和研制方过度研发或重复验证较低失败概率产品的风险概率,进而提出了高风险研发项目中研制方过度研发风险的概念,明确了工程决策误判风险与研制方过度研发风险的相互影响规律,并基于概率方法建立了一种可以综合权衡决策方风险和研制方风险、合理确定研制周期的系统工程优化方法。

Abstract:

Different risks associated with decision party and system developer are modeled and analyzed aiming at the high risk characteristics of hypersonic vehicle development.Based upon the inherent probabilistic risks of system design and critical technologies,a generic test and verification process is adopted to calculate the probabilities of accepting unqualified systems by the decision party,or over-testing low risk systems or technologies by the developer.The relation between decision risk and developer's risk is studied,and then a system engineering approach for balancing the risks as well as optimizing the development cycle is proposed based on probability calculation.

Key words: hypersonic vehicle, engineering development, developer's risk, decision risk, risk probability, systems engineering optimization
