In order to reduce the cost of the production cycle, the economic design of EWMA charts with variable sampling interval (VSI) under non-normality is discussed in this paper. First, using the Burr distribution to approximate various non-normal distributions, the optimal values of the test parameters for the VSI EWMA charts under non-normality will be determined such that the expected total cost is minimized. Further, the genetic algorithms (GA) will be used to search for the optimal values of parameters of the VSI EWMA chart under non-normality. Finally, a sensitivity analysis is carried out to economic modal and the effect of model parameters on the solution of the economic design is obtained.
