A Security Risk Assessment Method Based on Improved FTA-IAHP for Train Position System
نویسندگان
چکیده
The positioning system based on satellite navigation can meet the requirements of CTCS-4 train control, improve transportation efficiency, reduce operation and maintenance costs, which is trend in future, security risk assessment great significance to future application this system. In paper, combined with self-developed navigation, an improved fault tree-interval analytic hierarchy process (FTA-IAHP) method for evaluating safety proposed. Firstly, a model FTA-IAHP established by combining FTA IAHP. Secondly, two judgment matrices are constructed using basic events structural importance FTA, IAHP expert scoring, difference between adjusted weighting factor. new trial determine degree each factor fault. This has design protection navigation.

In this paper, we concentrate on the problem of assessing the network security risk via an improved Hidden Markov model. As is well known that Hidden Markov model is belonged to one of the regime-switching models, which have been successfully exploited to model time series data. However, the standard Hidden Markov model cannot effectively to represent the structure of holding times for a specif...

متن کاملA New Method for Spatial Health Risk Assessment of Pollutants
Background: The area of contaminated lands exposed to the health risk of environmental pollutants is a matter of argument. In this study, a new method was developed to estimate the amount of area that is exposed to higher than normal levels of Cr, Mn, and V. Methods: Overall, 170 soil samples were collected from the upper 10 cm of soil in an arid area in central part of Iran in Semnan Provin...
