A Methodology to Estimate the Reliability of Passageway system in Naval Ship Design

In this paper, we describe and demonstrate a general methodology to evaluate the reliability of the passageway system in warship design. The reliability of the passageway system is the most important component of naval ship survivability evaluation. Currently, most of the passageway evaluations focus on human factor or physical distribution; integrated calculates is lacking to estimate the reliability of the passageway system. The challenge for naval architects is to develop a systematic methodology that allows accurate evaluation of the passageway reliability associated with crews movement and related material operating procedure. The paper consults the concept of network reliability and lays out an evaluation method of passageway system based on task reliability. The method integrated analyses the impact of ship crew‘s location and distribution of the shipborne material. As it was difficult to achieve the reality data, the methodology is demonstrated using a hypothetical warship combining with the simulation software on the basis of two different evaluation scenarios.
