Research On Topological Structure Of Human-computer Interactive Information Network In Complex Task Environment

Complex system reliability analysis methods have always been a hot research topic in the field of complex systems,and play a vital role in preventing system failures and human error.Aiming at the defects of the traditional human system reliability analysis method,the pre-evaluation criteria are not uniform,the logical relationship between system elements cannot be accurately described,and the human-machine interaction interface optimization cannot be directly served.Analytical method.The main research contents are as follows:Firstly,taking the typical human-computer interaction complex system-F/A-18C fighter flight driving system as an example,from the perspective of human cognitive processing,the hierarchical mission analysis(HTA)is used to classify complex missions according to different granularities.The layers are disassembled until the level of the interface information element is manipulated,and then the logical association between the subtask and the cockpit interface information is quantified.Combined with the complex network theory,three layers of human-computer interaction information association networks with different granularity are obtainedSecondly,the static statistical characteristics of the topology of the three-layer interactive information association network are analyzed,and the importance degree of the information elements in the interface is obtained.The human-computer interaction information network has the law of small world characteristics The reliability simulation of the three-layer network is carried out.The analysis compares the analysis results with the actual fighter human error statistics to find the network description method that best matches the human cognition and memory mode.At the same time,it is proved that the complex network theory can effectively analyze the human factor reliability of the fighter flight system,and can provide the basis for the optimization of the human-computer interaction interface layout based on the reliability analysis resultsFinally,the human factors factors such as the interaction mode and information type of the original interactive interface of the fighter cockpit are analyzed in detail.Combined with the network reliability simulation and community structure analysis results,the original cockpit interface layout is analyzed and optimized.Thereby improving the reliability of the fighter flight system,reducing human error and ensuring flight safety.The research methods and conclusions can be extended to the relevant human-computer interaction complex system field,and the conclusion is universal...
