In this paper, the design of the control chart when the variable of interest follows the gamma distribution under the neutrosophic statistical interval method (NSIM) is proposed. The average run length, probability in-control, and probability of out-of-control will be derived using the NSIM. The neutrosophic control chart coefficient will be determined by the algorithm under the NSIM. The neutrosophic average run length for various shifts and specified parameters will be determined. The efficiency of the proposed control chart is discussed using the simulation study and a real example.
