Abstract :
This paper gives the method of control lines for the biased distribution based on the weighted standard deviation method which is used to construct the mean control chart for biased distribution of the unknown population, after control lines are determined, we give the estimation method for relevant parameters, and then comparative the effectiveness of standard deviation control chart by numerical example which are based on the weighted standard deviation method and the traditional Shewhart control chart method.
