Abstract
For characteristics of reliability, maintainability, supportability and multi-state about a navigation monitor network under real environment, Petri net (PN) and Bayesian network (BN) are applied integrated to availability modeling and analysis of a navigation monitor network in this paper. The relationship of equipments and MTBF, MTTR, MADT, sufficiency, MSRT of spaces are combined for availability modeling of monitor stations by PN. According to normal, degraded and failed states of monitor stations, availability modeling of the monitor network are obtained by BN. By analysis, nominal availability, degraded availability and failed state probability of the monitor network and weakness of monitor stations are confirmed. The multiple schemes are proposed and compared for improving availability. The result shows, improving sufficiency plays a more role in improving availability under real environment, and this method can be used for availability modeling and analysis.
