Abstract
In order to avoid that the settlement exceeds the budget in the construction process of power transmission and trans-formation project,the whole process cost risk modeling and evaluation method of power transmission and transformation pro-ject based on grey theory is proposed.The characteristic mapping model of cost risk identification in the whole process of power transmission and transformation project is established.The analysis sequence,the analysis matrix,the grey correlation degree,the grey theory to calculate the estimate and settlement cost information respectively,the risk function and probability density function,and the cost risk of the whole process of power transmission and transformation project according to the expected val-ue and variance of the risk function.Simulation experiments show that this evaluation method conforms to the law of risk,can correctly identify sensitive factors,and is helpful to better control the cost of engineering construction.关键词
