Based on the reliability index of a new-type towed anti-aircraft gun system, the inherent reliability level of the gun system is calculated. The effect of the system reliability parameters on the system's performance is assessed, and the application of design principle of system-reliability-centered maintainability and supportability to complex systems is analyzed.
Based on in-depth analysis of the status of construction method of security evaluation index system and the operating system of special dangerous goods destruction, this paper obtained the purpose of safety evaluation index system and principles. At the same time, by improving the quantitative research of the traditional pre-hazard analysis (PHA), it created analysis mode of risk factors based on...
According to the background of attackers' accomplishment of breaking through and attacking enemy's rear ground target, penetration effectiveness model of attackers is constructed. After theoretical analyzing the affection of using airborne electronic jamming measures and anti-radar missile to the penetration effectiveness and some simulation examples, the rationality of the model is verified. The...
Starting from the demand for antagonizing anti-radiation weapons of fire control radar, the principle of intermittent target tracking of fire control radar network is introduced, and the fire control radar network simulation system based on high level architecture is designed, the functional structure of the simulation federation and the simulation process of federal members is analyzed. In order...
Based on the principles of reliability and maintainability, a type of gun fire control system was taken as research object. The method combining the system composition character with the system reliability index allocation model was used to realize the technique of system reliability. The system failure rate and fault distribution principle were combined with maintainability realization principle...
The subway is a kind of transportation with complex technology and crowded passengers. Individual and society will be seriously affected by accidents of subway system. So the most important issue on subway operation is to develop safety risk analysis methods. This paper firstly introduces the concept of safety risk on subway operation. Then a category of safety risk events on subway operation is developed...
A new fault prediction method based on dynamic fuzzy comprehensive evaluation is presented. By the confirmation of the dynamic weight coefficient set and the dynamic fuzzy relationship matrix, a fault prediction model for shell-feeding system is established. The expression of fuzzy knowledge is presented. The hybrid inference mechanism included dynamic fuzzy comprehensive evaluation and production...
