Study on Reliability of the Train Opertion Dispatching

Railway traffic control is the command center of the daily railway transportation organizations , he is charged with ensuring transportation safety , organization of passenger and freight transport , to ensure that key national transportation , improve the important responsibility of the passenger and freight service quality production and operation tasks , the completion of the railway transport , railway transport enterprise effective plays an important role . The core of the railway transportation scheduling is the the train scheduling work , all related to rail transport departments of various types of activities must be under the command of the unified organization of the transportation scheduling . Train scheduling work involved many departments , the use of rule complexity , dynamics, and strong real train scheduling subsystem is closely related to production safety , the information infrastructure of the subsystem railway scheduling system , it determines the whole railway system reliability reliability. Train dispatching operations involved in train operation adjustment , release scheduling command , abnormal operating organization critical aspects are also scheduling a manifestation of the ability to command . If there is a loophole or error in these aspects , ranging from transport disorder blocked traffic generated accident . In addition, the combination of inter-ministerial coordination is also a great impact on system reliability . The dispatch command - machine - environment of large-scale systems , the safety of the people is very important , reliability is the most fundamental reliability . From human error mechanism to start the analysis of the impact of human reliability factors , Reliability theory of computing reliability through the development of appropriate corrective measures to improve the personnel system by analysis of the calculation to find out the inadequacies of the personnel system at reliability. Analysis of train dispatching system reliability allocation based on the reliability of the relationship between various subsystems work to build a train dispatcher working reliability logic diagram , and the train dispatch reliability modeling analysis , to clear system work in each sub- the weak link of the system between system through the development of preventive measures , to improve the overall reliability of the system , so as to ensure the security and stability of railway transportation .
