Diagnosis operational safety of a transport system

The transport systems are sociotechnical systems in which the direct realization of the tasks is dealt with by an executive subsystem consisting of the elementary subsystems of a human – a technical object (an operator – a means of transport) type realizing the tasks within the system environment. In respect of a human located within a transport system the most significant criterion in the evaluation of transport being realized is their safety.The safety level of the task realization is influenced by the risks resulting from the interaction of the forcing factors, affecting an elementary executive subsystem.These factors may be divided into [8]:-working;-external;-antropotechnical.Due to the complexity of the systems being analysed in the paper, it has been attempted to evaluate the influence of the forcing factors on the safety of this system operation.
