This paper presents the economic design of modified X chart for autocorrelated data and comparison with the economic design of Shewhart's X chart. An attempt has been made to counter autocorrelation by designing the modified X chart; as the cost of operating a process control system is an important element in the economic design of control charts. The economic designs of both modified and Shewhart X charts for autocorrelated observations are presented; using Lorenzen-Vance  cost model.
