Chapter 6 - Reliability Evaluation of Port and Shipyard Transportation Systems

Abstract

This chapter applies the multistate asymptotic approach to reliability and risk characteristic evaluations of selected large transportation systems used in ports and shipyards. Reliability analysis of multistate series, series-parallel, and parallel-series transportation systems is based on corollaries. Corollaries are used to evaluate reliability characteristics of three transportation systems used at the Port of Gdynia and one used at the naval shipyard of Gdynia. The chapter analyzes the applicability of the multistate asymptotic approach in a number of systems, such as the port grain transportation system built of three-state non-homogeneous series-parallel subsystems, the port oil-piping transportation system composed of three-state nonhomogeneous series-parallel subsystems, the port bulk transportation system built of four-state nonhomogeneous series-parallel and series subsystems, and the shipyard rope transportation system that is a four-state homogeneous parallel-series system. The accuracy of the asymptotic approach to the reliability evaluation of these systems is also determined. System components reliability data and system operation processes data come from experts operating these systems, component technical certificates, and obligatory norms. Reliability data by necessity are approximate and concerned only with the mean values of the system components' sojourn times in the state subsets and hypothetical distributions of these lifetimes.
