Safety of Complex Technical System Impacted by Its Operation Process

An innovative approach is proposed to safety analysis of multistate ageing systems impacted by their operation processes. A safety function and other safety indicators are defined for a complex multistate ageing system changing its safety structure and its components safety parameters during the operation and determined under the assumption that its components have piecewise exponential safety functions. Results are applied to examine safety of port and maritime transportation systems.

Keywords: Multistate system, Ageing, Operation process impact, Safety, Transport, Port oil terminal, Maritime ferry.
