技术性能风险度量方法及应用

摘要

技术性能风险度量(Technology Performance Risk Measures)是评估系统达到性能要求程度及完成剩余性能要求风险的度量,是技术性能度量(Technology Performance Measures)概念的拓展.技术性能度量指标只反映了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,难以反映综合风险.在已有技术性能度量研究的基础上,拓展了技术性能指标分类种类,进一步综合考虑系统完成剩余性能风险的困难程度,提出技术性能风险度量方法,给出了该方法的划分方法并在实例中验证了方法的适用性.%Technical Performance MeasuresfTPRMs) are defined and evaluated to assess how well a system is achieving its performance requirements and the risk to achieve the unmet performance requirements, and the TPMs (Technology Performance Measure) is the basic of TPRMs. TRMs only accounted for the achieved performance instead of both the achieved and unmet performance, so it is impossible to reflect the aggregated risk. This paper firstly extended the technology category in TPMs. Secondly, the proposed TPRM 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 were given in the paper.
