摘要 针对目前我国水利工程建设市场"双随机一公开"监管制度实行中采用的常规随机抽样方法存在抽检不均衡问题,提出一种均衡性改进的抽取方法。该方法在随机抽取的基础上,考虑被抽取对象的抽中次数,提高被抽取次数较少的对象的被抽中概率,使抽取结果趋于均衡;引入专家经验系数来调整检查人员抽取概率,改善抽取结果。根据检查人员和被检查对象的不同特点,分别建立不同的改进模型,并应用概率的方法对改善效果进行定量分析. Aiming at the problem of random sampling unbalanced in the conventional random sampling method adopted in the implementation of the " double random and open " supervision system in China ' s water conservancy construction supervision market , a method of improving the equilibrium was proposed. On the basis of random extraction , the method considered the number of extractions of the extracted objects , improved the probability of extraction of objects with fewer extraction times , and made the extraction results tend to be balanced. For the in-spectors , the expert experience coefficient was introduced to adjust the probability of the extraction and improved the extraction result. Ac-cording to the different characteristics of the law enforcement inspectors and the objects to be inspected , different improved models were es-tablished , and the probabilistic methods were applied to quantitatively analyze the improvement effects.
