A method for calculating the similarity of normal cloud model is studied. The concept of shape similarity and distance similarity of normal cloud model is proposed, the framework of integrated similarity measurement of cloud model is established. The shape similarity of normal cloud model calculation formula is given combined with digital feature of the cloud model. The influence relation and mathematical prop- erties of distance between two cloud models on similarity are studied, the definition of similarity measure based on distance is proposed and a convenient computing method is studied. The example illustrates the feasibility of the algorithm.
