Safety and operation cost optimization of port oil terminal critical infrastructure

The model of system safety impacted by operation process is introduced and the procedure of its safety maximization is proposed. The model of system operation total cost during the fixed operation time is introduced and the procedure of its minimization is presented. To analyse jointly the system safety and its operation cost optimization, we propose the procedure of determining the optimal values of limit transient probabilities of the system operation process at the particular operation states that allows to find maximal system safety indicators, through applying the created system safety model and linear programing. Next, to find the system conditional operation total cost during the fixed operation time, corresponding to this system maximal safety indicators, we replace the limit transient probabilities at the particular operation states, existing in the formula for the system operation total cost during the fixed operation time, by their optimal values existing in the formulae for the coordinates of the system safety function after maximization. The created models are applied to the port oil terminal critical infrastructure to maximize its safety indicators and to minimize its operation total cost during the fixed time separately. After that the port oil terminal critical infrastructure operation total cost during the fixed operation time corresponding to its maximal safety indicators is found. The evaluation of results achieved is performed and the perspective for future research in the field of the complex systems including critical infrastructures safety and their operation costs joint analysis and optimization is given.
