Modelling environment and infrastructure of shipyard transportation systems and processes

Blokus-Roszkowska A., Kołowrocki K.

Journal of Polish Safety and Reliability Association

2008

Vol. 1

77--84

In the paper an analytical model of port transportation systems environment and infrastructure influence on their operation processes is constructed and presented in an example of shipyard rope transportation systems in Naval Shipyard in Gdynia. A general semi-markov model of a system operation process is proposed and the methods of its parameters statistical identification are presented. Further, the shipyard rope transportation system and the ship rope elevator operation processes are analyzed and their operation states are defined. A preliminary collection of statistical data necessary to the ship transportation systems’ operation processes identification is included.

A multi-state approach to defining basic notions of the system safety analysis is proposed. A system safety function and a system risk function are defined. A basic safety structure of a multi-state series system of components with degrading safety states is defined. For this system the multi-state safety function is determined. The proposed approach is applied to the evaluation of a safety function, a risk function and other safety characteristics of a ship system composed of a number of subsystems having an essential influence on the ship safety. Further, a semi-markov process for the considered system operation modelling is applied. The paper also offers an approach to the solution of a practically important problem of linking the multi-state system safety model and its operation process model. Finally, the proposed approach is applied to the preliminary evaluation of safety characteristics of a ship system in varying operation conditions.
