摘要
针对船舶核算系统在运行过程中的安全性无法保证问题,为了提高船舶核算系统的安全性,提出Web Service技术的船舶核算系统安全功能设计研究。利用船舶核算系统的概率密度函数,根据先验分布函数和系统电子元器件样本分布函数,得到了船舶核算系统的后验概率密度函数。根据船舶核算系统的可靠性理论,计算了船舶核算系统失效率的上限值,结合数学期望理论的定义,计算了船舶核算系统的失效率,通过引入Bayes估计理论,评估了船舶核算系统的失效数据,实现船舶核算系统的安全功能设计。实验结果表明,基于Web Service技术的船舶核算系统安全功能不仅可以提高核算数据资源占用率,还可以提升系统的兼容性,从而提高了船舶核算系统的安全性。
In view of the fact that the security of the ship accounting system can not be guaranteed during operation, in order to improve the security of the ship accounting system, a research on the design of the security function of the ship accounting system based on Web Service technology is proposed. The posterior probability density function of ship accounting system is obtained by using probability density function of ship accounting system, according to prior distribution function and sample distribution function of system electronic components. According to the reliability theory of ship accounting system, the upper limit of failure rate of ship accounting system is calculated. Combined with the definition of mathematical expectation theory, the failure rate of ship accounting system is calculated. By introducing Bayes estimation theory, the failure data of ship accounting system is evaluated, and the safety function design of ship accounting system is realized. Experimental results show that the security function of ship accounting system based on Web Service technology can not only improve the occupancy rate of accounting data resources, but also improve the compatibility of the system, thus improving the security of ship accounting system.
