Reliability and Safety of Complex Technical Systems and Processes

Integrated model of port oil piping transportation system safety including operating environment threats

“…In the safety analysis of multistate systems at the variable operation conditions, to define the system with degrading components we assume that the changes of the system operation process Z'(t) states have an impact on the system's components and its structure [7]. Moreover, in this section we assume that the system components at the system operation states have the exponential safety functions.…”

“…In [7], it is fixed that the port oil piping transportation system safety structure and its subsystems and components safety depend on its changing in time operation states. The influence of the system operation states changing on the changes of the system safety structure and its components safety functions is given in [2], [5].…”

“…where according to (7) and considering the pipeline system operation process transient probabilities at the operation states given by (11), the vector coordinates are given respectively by …”

Operating environment threats influence on the maritime ferry technical system safety – the numerical approach

“…In [7], it is fixed that the maritime ferry technical system safety structure and its subsystems and components safety depend on its changing in time operation states. The influence of the system operation states changing on the changes of the system safety structure and its components safety functions is given in [2], [5].…”

“…The common safety and operation including operating environment threats analysis of complex technical systems and critical infrastructures is of great value in the industrial practice. The convenient tools for analyzing this problem are the multistate system's safety modeling [7] commonly used with the semi-Markov modeling [6], [10] of the systems operation processes including operating environment threats [2], leading to the construction the joint general safety models of the complex technical systems and critical infrastructures related to their operation process and the operating environment threats influence on their safety structures and their components safety parameters [5]. The paper presents a general procedure for numerical approach applied to determine safety characteristics of the maritime ferry technical system and its components, related to its operation process including operating environment threats.…”
