Reliability Assessment on Landmark Fixing Operation Based on Cloud Model

This paper has put forward analysis method based on cloud model for the reliability analysis of landmark positioning operation. The cloud model can realize the bilateral switching between qualitative concept and quantitative value. The three digital features are obtained through reverse cloud algorithm, which reflects the personnel operation level and the dispersion degree and stability of the operation. The personnel operation can be imitated through forward cloud algorithm so as to obtain the simulated cloud chart of actual operation point. The standard cloud is established by a series of standards, we use the standard cloud which is most similar to the actual operation as the evaluation result of the operation. The assessment of landmark positioning operation of the navigation operation personnel of a flight can prove this method is of reference value and strong practicality for the analysis on landmark fixing of navigation operation personnel.
