Combining the stochastic weight assignment method for weights calculation and the Monte-Carlo simulation method,this method is used to analyze the effects of the changes of weights on evaluation results,which can be used in comparative analysis of multiple programs.

In the model,the stochastic weight assignment method is used to determine the value of weight.

In the model,the stochastic weight assignment method is used to determine the value of weight,and then Monte-Carlo method is used to solve the model.

The target weights are determined through stochastic weight assignment.

Aimming at the small sample of strapdown inertial measurement unit (SIMU) successive test data, a random weighting method is used to get the prior distribution function of population’s parameter with the known prior information under the situation that the parameters’ format of general distribution is unknown.

Bootstrap method and random weighting method are used to assess the individual bioequivalence(IBE),the power of hypothesis test is simulated,power of random weighting percentile method is the most excellent.

The problem of missile hit accuracy assessment is studied by using prior information and extra small field samples Based on Bayes theory and stochastic weighted method, a new method of accuracy assessment has been put forward and validated by some calculated examples.

To avoid "error alarm" caused by traditional control charts under small amount of sample, the stochastic weighted method and Bayes method were respectively adopted to estimate parameters of check data’s distribution when check data had historical information or not.
