摘　　要：主要研究了全局灵敏度分析法在解决实际问题中的优点和不足,提出了基于均值和方差的多个局部灵敏度参数评价全局灵敏度,并用多属性决策机制进行灵敏度排序的双参数灵敏度分析方法。该方法克服了单一参数评价全局灵敏度的缺陷,不需知道输入变量和输出响应的分布规律,可以采用较少的数据量得到可信的结果,为复杂非线性黑箱系统参数灵敏度分析提供了新的思路,通过实例验证了本方法的有效性和可信性。Through research on the advantages and disadvantages of main global sensitivity analysis method in the course of solving practical problems,the Dual-parameters Sensitive Analysis method（ DGSA） based on mean value and variance of multi local sensitivities in definition domain that was used to access global sensitivity was proposed,while multi-attributes decision-making method was used to calculate the sensitive value by the above two parameters. DGSA method overcomes the defect of global sensitivity accessed by single parameter. Since the distribution patterns of input variable and output response are dispensed with,a credible result can be obtained with less data. As a result,a new method to solve this type of problems is provided. An example was used to verify the validity and credibility.
