Research On The Adaptability Of Human Factors Methods For Complex Man-machine System

With the prosperity and development of the human factors engineering field,the number of human factors methods is showing an increasing trend.The diversification of human factors methods allows human factors engineering analysts to have more choices when solving human factors problems in complex man-machine systems,but at the same time,it is difficult for analysts to make decisions when choosing methods,therefore,it is necessary to study the adaptability of human factors method.Based on the analysis of the current status of the research on the adaptability of human factors methods and the combination of method selection research in other fields,a general framework for the analysis of human factors method adaptability was proposed in this thesis,the human factors method categories and the human factors problems mapping model and the human factors methods selection model were constructed.The main contents and research results of this thesis are as follows:(1)A set of human factors methods was constructed.Through a large amount of literature research and analysis,a set of human factors methods including 13 categories and 134 methods was constructed,which provide a basis for methods adaptability analysis.The 13 categories method including data collection methods,task analysis methods,cognitive task analysis methods,process charting methods,human error identification and accident analysis methods,situational awareness assessment methods,mental workload assessment methods,team assessment methods,interface analysis methods,design methods,performance time prediction methods,and body-related methods and environmental related methods.(2)The human factors problems and human factors method categories mapping model was constructed.By introducing the three-dimensional complex man-machine system analysis model,we established a standard process for human problems identification,this process divides the target complex man-machine system into multiple sub-units to propose human factors problems.Then,we constructed a human factor process analysis process,matched human factors problems with method categories to realize the selection of human factors method categories.(3)A selection model of human factors methods based on a multi-index fuzzy comprehensive evaluation was constructed.The evaluation indicators of this model cover the reliability,validity,application time,training time,tools,and number of people needed for human factors methods.Based on the determination of the evaluation indicators,we have also completed the grading of all human factors methods in the above indicators in the set of human factors methods.(4)A software system for adaptability analysis of human factors methods for complex man-machine systems was developed.The system integrates a database of human factors engineering methods,integrates human factors problems,and human factors method categories mapping model and human factors methods selection model,which can realize the adaptability analysis of human factors methods for arbitrarily complex man-machine systems.Finally,we also applied the software system and method to the analysis of the human factors methods adaptability of the rail transit dispatching command system,verified the feasibility of the proposed human factors method adaptability analysis method.This thesis proposed an adaptive analysis method for human factors methods for complex man-machine systems,this analysis method can provide method selection ideas for decision-makers of human factors methods.This method is objective and simple,and can reduce the subjective influence of decision makers.It provides effective assistance to solve the human factor problems in the complex man-machine system,and also aids with the realization of human-system integration,thereby reducing the cost of system operation and improving efficiency.
