Design And Evaluation Of Ship Power System Software Interface Based On Human Errors

The main function of the ship power system is to monitor and remotely control the real-time status of various types of electrical equipment and electrical equipment of the ship.Operators often need to monitor multiple types of complex data at the same time.Unreasonable interface information design is easy to bring to the operator.The mental workload and operating pressures cause operational ergonomics to be low and prone to human error events.For this kind of problem,this paper will study the cause of human error in the interface operation,and from the perspective of human identification,search,processing,and response mechanism,analyze the human error of the ship power system software interface.Optimize its design to increase its availability and reliability,thereby reducing the incidence of human error.The main research work of this paper is as follows:First of all,through the analysis of the application of human error theory in the interface design,combined with human visual cognition and human information processing and processing model,it provides a theoretical basis for human error analysis of ship power system software interface software interface.Secondly,after comparative analysis of various types of human error analysis models and methods,the PHEA predictive human error analysis model was selected to analyze the human error of the ship power system software interface,and three software modules for visual monitoring,decision-making,and operation of the software interface were extracted.Due to the error impact factor,the comprehensive visual cognition characteristics,human information processing model,and ship power system standard specification put forward the principles of software interface design for the ship power system,including the principles of identification design,consistency design,and normalization design.Detailed description of these three aspects of the design principles.Thirdly,the system structure of the ship power system is analyzed,the interface layout is analyzed abstractly,the final layout method is determined,and the optimal design is designed according to the software interface design principles of the ship power system.Simultaneous prototyping with Photoshop and Axure RP design methods.Finally,select the WP(the Workload Profile Index Ratings)mental workload self-assessment scale,the iconic symbolic ease-of-use questionnaire,the two types of subjective evaluation methods,and the typical target task performance questionnaire,the interface information volume calculation,and the eye movement physiological experiment measurement.The usability comprehensive evaluation system combined with the objective evaluation method evaluates the software interface optimization design scheme and the original plan of the ship power system.The experimental data analysis shows that the ship power system software interface optimization design plan has higher usability than the original interface.At the same time,it also proved the validity of the design principles,and further verified the low incidence of human error in the software interface optimization design scheme for ship power systems..
