Train dispatch system reliability with strong wind predicting and warning system

With strong wind predicting and warning system setup, train dispatch system structure will change, and will bring change of work process and reliability of the whole system. In order to build a high reliable railway dispatch system, the paper analyzes three railway dispatch system structures and their fuzzy reliability. The first dispatch system with no wind warning system, the second and the third dispatch system connected to the wind warning system but have different work flow. Through building system fuzzy reliability model, the three systems reliability are calculated and compared by an example at last. The example shows that the fuzzy reliability model is effective and can be used to evaluate reliability of the new train dispatch system.
