【摘要】 星载测绘相机对于信息化、智能化的要求越来越高,高可靠性星载测绘相机主控软件是星载测绘相机的重要组成部分。为了保证星载测绘相机主控软件的可靠性,对星载软件可靠性分配指标的定量衡量与分配进行研究。针对以往的软件可靠性分配模型无法定量衡量评价指标的问题,将熵理论引入软件可靠性分配模型中,提出了一种基于熵权的软件可靠性指标分配模型;并针对星载测绘相机主控软件各软件部件进行了可靠性指标分配。计算结果表明:为各软件部件分配可靠性指标后,系统的可靠度为0.95588,满足对系统可靠性的要求。在保证系统可靠性的前提下,能够实现对星载测绘相机主控软件各软件部件可靠性指标的合理分配。更多还原

【Abstract】 On-board mapping cameras need high requirements of information and intelligence,high reliability onboard mapping camera’s master control software is an important component of the on-board camera.It is a current study emphasis on how to improve the reliability of the software.In order to ensure the reliability allocation of onboard mapping camera’s control software,the paper researches on quantitative measurement to allocation indicators.In view of the past reliability of the distribution model can not be measured quantitatively by evaluation index,the paper has introduced the theory of entropy distribution model to software reliability for the first time,and brought forward software reliability allocation model based on the entropy,and distributed reliability index to the software components of on-board mapping camera.After distributed reliability index to the software components,the system’s reliability is 0.95588.The results show that on the condition of the system’s reliability,the software components can achieve a rational allocation of reliability.更多还原
