Application Of Improved Human Cognitive Reliability In Ship Engine Room Layout Optimization

With the frequent trade between countries,ocean transportation has become an indispensable mode of transportation,and ships are playing an increasingly important role as the main means of transportation.With the continuous improvement of the level of science and technology,there have been few maritime accidents caused by ship hardware problems in recent years,but the maritime accidents caused by human factors have become more and more serious.As the heart of a ship,the design of the engine room has a very important impact on the smooth operation of the ship.However,human factors are rarely considered in the traditional design method,which will lay a safety hazard for the navigation of the ship.Moreover,in the design of the general arrangement of the ship,the economy is generally considered,and the space of the engine room will be designed to be relatively small,which will cause the operator to make mistakes due to the lack of working space during operation,posing a threat to the safety of the ship.In order to reduce the occurrence of marine accidents caused by human error in the engine room,the influence of human factors should be considered in the early stage of engine room design.Therefore,this study starts from optimizing the layout of the engine room to improve the human reliability while ensuring the correlation between the equipment and the balance of the hull.The main research contents of this paper are as follows:Firstly,the overall engine room and equipment layout principles are summarized;the crew responsibilities,engine room maintenance tasks and factors affecting the crew are analyzed,and the relationship between human reliability and engine room environment is clarified;according to the design characteristics and influencing factors of the engine room layout,a engine room equipment layout evaluation system.Secondly,it analyzes several commonly used human factors reliability analysis methods,and proposes an improved HCR method suitable for the optimal layout of the engine room based on the characteristics of the engine room environment.function to build a mathematical model for the optimal layout of cabin equipment.Thirdly,based on the simulated annealing algorithm,the mathematical model of engine room layout optimization is solved,and the solution tool is developed through programming software,and the practicability of the solution tool is verified by optimizing the engine room layout example of a multi-purpose ship.Finally,the AHP method is used to assign weights to each level of the cabin layout,and the fuzzy comprehensive evaluation method is used to make a fuzzy comprehensive evaluation of the plan before and after the optimized layout of the ship’s engine room,so as to verify the effectiveness of the layout optimization method.
