Research On Man-machine Interface Integrated Evaluation For Large-scale Ship Wheelhouse

With the rapid development of China’s shipdesigning and shipbuilding industry, toimprove the wheelhouse man-machine interface design of independently developedlarge-scale ships, has an important role in the reduction of the wheelhouse human error,enhancement of the system efficiency, and protection of the ship safe navigation. Integratedevaluation is an important means to examine the attribute value and determine the problemsor flaws of the wheelhouse man-machine interface, and to safeguard its quality design. Inthis paper, the wheelhouse man-machine interface has been due to the researching object,the necessity and development status of man-machine interface integrated evaluation theoryand methods have been analyzed. The key issues of evaluation elements and criteria system,evaluation indexes system, weighting method, integrated evaluation theory and digitalevaluation technical means were researched. The main research work including:The characteristics of the man-machine interface of wheelhouse were analyzed, and theintegrated evaluation researching model was established based on the proposed generalizedSHEL model. The wheelhouse man-machine interface evaluation elements were studiedfrom the relationships of liveware-hardware, liveware-software, liveware-environment andliveware-liveware, as the basis to build the integrated evaluation index system structure ofwheelhouse man-machine interface. The characteristics, application methods and principlesof man-machine interface evaluation standards of wheelhouse both domestic and foreignwere studied, and the evaluation standards system of wheelhouse man-machine interfacewas constructed, as the foundations of extracting the basis individual evaluation indexes,and implementing the integrated evaluation.On this basis, the constructing aim, constructing method and testing method forwheelhouse man-machine interface evaluation indexes system was studied; the structure ofintegrated evaluation indexes system was formed based on the wheelhouse workgroundman-machine interface, wheelhouse work environment, wheelhouse work team and thewheelhouse software; the basis individual evaluation index sets were filtered and extracted.The integrated evaluation index system testing methods was established to test thecompleteness and redundancy of the wheelhouse man-machine interface evaluationstructure, to test the necessary, identification and feasibility of the basis individualevaluation index. And the subjective and objective indexes evaluation data processingmethod was studied. The improved AHP group weighting method based on feedback mechanism wasproposed. The evaluation weight matrix scaling method was established. And the instanceverified its superiority for the weights assigned order-preserving, consistency, uniformityand so on. Combining Delphi method principle, group evaluation feedback mechanism andweights calculating method were studied; the group weighting divergence degree indicatorwas constructed based on grey similarity incidence to control the group weighting feedbackmechanism. And the exhaustive weights relationships of integrated evaluation index systemof wheelhouse man-machine interface were determined.The integrated evaluation theory and method were studied. For the fuzzy uncertainty ofthe subjective evaluation information, the cognitive fuzzy integrated evaluation method wasconstructed based on the subjective interval value set. The subjective evaluation informationambiguity expression mode was studied. The gravity center model was used to determinethe focus of the subjective evaluation interval value sequence. And the focus confidencecoefficient was constructed to verify the group judged interval value sequence focus. Forthe gray of the integrated evaluation information, the gauss distribution whitening weightsof was proposed to descript the value distribution of evaluation information. The grayclustering evaluation method based on the gauss distribution whitening weights of wasproposed, for the accurate quantification and statistical evaluation information value, toclustering evaluate the subjective and objective integrated evaluation results.The digital wheelhouse man-machine interface integrated evaluation software systemhas been developed. The standard model library of wheelhouse equipments, digital crewhuman body model and visual simulation subjective evaluation model were developed; theobjective and subjective evaluation environment for wheelhouse man-machine interfacewas constructed. Finally, the digital integrated evaluation system was applied to evaluate thewheelhouse workground man-machine interface design. The evaluation result was analyzed,and improvement recommendations for the specific design elements and new design wereproposed. It is to verify the proposed integrated evaluation theory methods and evaluationtechnical system for man-machine interface of large-scale ship wheelhouse.
