A Comprehensive Reliability Assessment Method for Existing Railway Bridges Based on Bayesian Theory
نویسندگان
چکیده
The increase in traffic volume and train load poses new challenges to the reliability assessment of existing railway bridges. To construct a comprehensive method for safety bridges, firstly, risk factors bridge structures are analyzed evaluation criteria determined; secondly, based on accident tree theory, multilevel Bayesian network model with key points is established, ability bidirectional reasoning sensitivity analysis used evaluate structural safety; finally, result was applied marina northern Songhua River extra-large verify applicability an bridge. This approach provides theoretical basis maintenance reinforcement Bridge along Bin-North Line.

متن کاملMulti-state system reliability assessment based on Bayesian networks
This paper considers a problem of multi-state system reliability modelling and assessment. By using the advantages of uncertainty reasoning and figurative expression of Bayesian network, a new method of modelling and assessment of multi-state system reliability based on BN is proposed to determine the nodes of BN and the multiple states of components of system, and to give the probability of ea...

متن کاملGUI Reliability Assessment based on Bayesian Network and Structural Profile
Graphical User Interfaces (GUI) is becoming increasingly important in the software field as it builds a friendly way between users and software through continuous interactions. A well-developed GUI is therefore an important factor of software quality. In particular, the reliability of GUIs is still on the way of development. Existing software reliability assessment techniques attempt to statist...
