Research On The Configuration Design Model And Operational Risk Assessment Of Life Saving Equipment System For Cruise Ships

Cruise ship perfectly combines comfortable travel,excellent service,and diverse experiences,and is known as the "Sea Mobile Resort".Cruise travel is popular with tourists all over the world.The cruise market is showing a booming trend,especially in Asia,with China as its core.However,a cruise ship is different from an ordinary passenger ship in that it has a large number of decks,a complicated layout design,and a large number of passengers and crew.Therefore,how to avoid and reduce casualties during the evacuation process after the accident has always been a key issue in the safety design of cruise ships.This article provides scientific guidelines for improving cruise safety by studying the design and configuration rules of cruise lifesaving equipment systems and the use of risk assessment methods.In order to carry out a more reasonable configuration design of the cruise lifesaving equipment system,functional analysis and classification of the lifesaving equipment required by the cruise ship,and analysis of the existing cruise lifesaving equipment specifications,combined with the configuration design of a typical cruise lifesaving equipment system Characteristics,the cruise ship life-saving equipment system configuration design rules.On this basis,the reasoning method based on the combination of rule-based reasoning(RBR)and case-based reasoning(CBR)in knowledge engineering is selected to establish a cruise ship lifesaving equipment system configuration design model.Based on the proposed configuration design model,Visual C ++ was used to develop the configuration design software for cruise lifesaving equipment systems.And use this software to configure the lifesaving equipment system of Vista cruise ship.By comparing the actual configuration results with the software design results,it is found that the software calculation results have only an 8% deviation from the actual configuration results,which confirms that the proposed design method is effective for implementation.Applicability of rational configuration design of cruise lifesaving equipment systems.Aiming at the risk assessment of the cruise lifesaving equipment system during its use,the existing failure mode and impact analysis(FMEA)was improved by analyzing the fuzzy evaluation method and gray correlation decision method,and a new method for the use of cruise lifesaving equipment systems was proposed.Risk assessment methods.Through case analysis,it is found that the use of fuzzy evaluation to evaluate the risk factors of potential failure modes can effectively reduce the subjective impact of the assessor on the evaluation results,and combined with the gray correlation decision-making method to carry out risks on the identified failure modes The sequencing can more accurately indicate the danger level of the failure mode,and provide improvement measures for the more dangerous failure mode,thereby effectively improving the safety performance of the cruise lifesaving equipment system.This paper uses knowledge modules and inference engines for the first time to explore the design mechanism of cruise lifesaving equipment systems,and verifies the applicability of the method through examples,and solves the problem of configuration and design of cruise lifesaving equipment systems.The FMEA method was improved and applied to the risk assessment of cruise life-saving equipment systems.The effectiveness of the method was verified through an example analysis and the problem of risk assessment of cruise life-saving equipment systems was solved.It has certain guiding significance for improving the navigation safety of cruise ships in the configuration and design process of life-saving equipment systems.
