To solve the problem of the existing cloud barycenter evaluation methods,i. e. the parameter value determination of the cloud evaluation generator was not suitable,the two-entropy rule was proposed,and based on the rule the determination model of excess entropy parameter was established. The method to figure out the difference of degree between interval numbers presented by individual experts resulted in the mean interval number being proposed. The model to determine hyper entropy parameter according to the difference of degree was also established.To solve the problem solving model of cloud barycenter complex and deviation. The proportional conversion relationship between the interval number defined by the quantitative evaluation level and the interval number of the corresponding qualitative evaluation term was established. The quantitative index aggregation value was mapped to the interval number of the corresponding qualitative evaluation term,and the model to compute the dispersion of integrated cloud barycenter was simplified. The scientific nature and rationality of the improved model are validated by an example of the shipborne gun maintainability evaluation.
