系统技术性能风险度量方法及其应用

针对一般技术性能度量(TPM)指标只反映系统达到其性能要求的度量指标，未考虑系统完成剩余性能要求的困难程度，难以反映系统综合风险的缺陷，拓展技术性能指标分类种类，在传统TPM方法的基础上增加一类技术划分，并给出这类技术划分的TPM计算公式。综合考虑系统完成剩余性能风险的困难程度，提出技术困难程度的概念和技术性能风险度量方法，采用实例证明了两方面工作的适用性。

Technology Performance Risk Measure Method for System and Its Application

Aiming at the problem that Technical Performance Measure（TPM） only accounts for the achieved performance instead of both the achieved and unmet performance, it is impossible to reflect the aggregated risk. This paper extends the technology category in TPM. A new kind of technology is added to the traditional TPM and the calculating formula is given. The proposed TPM is based on two concepts： the unmet performance and the degree of difficulty with the unmet performance. In order to demonstrate how to use this method, two applications are given.
