“…Failure fluctuation focuses on subsystem 1to 7.When the hanger is firing and its firefighting subsystem failure has occurred , aviation lifting machinery room is very easy to catch fire.So some measures are taken to reduce the failure connection for this set pair.On the basic of the brittleness theory [15],there are two kinds of reason that cause the failure of a system .That is internal cause and external cause of a system.Therefore measures can been taken from two aspects.One is that negative entropy [16] is introduced into this system to reduce the failure of this system,such as improving the patrol inspection regulation and decreasing human error,etc. In another respect, step are taken in the inner system to chang the fire-fighting index parameters.For example, flammable materials of a cabin should be palced reasonably and the triggers are checked regularly.…”

There are complexity and cascading failure in ship fire-fighting system. According to the characteristics of ships,set pair analysis is used from overall system to subsystems.This paper analyzes the failure factors and establishes a cascading failure hierarchy correlative model of this fire-fighting system . Considering occurrence uncertainty such as fuzzy state ,random state and medium state of the failure factors ,this paper introduces how to solve a correlation degree of this system cascading failure based on set pair analysis in detail,and objectively measures the cascading failure probability and the reliability of this ship fire-fighting system. Cabins are seen as subsystems. Failure structure model of NO.3 watertight area is builded.Failure connection includes failure identity, failure discrepant,and failure contrary with set pairs.It determines two adjacent fire-fighting subsystems of cabins that failure connection is compact. This research shows the validity of set pair analysis in cascading failure analysis of ship fire-fighting system.
