Abstract

In this article, we propose a new t-chart for monitoring a process under the assumption that the time between events follows the exponential distribution. The proposed t-chart has double control limits that use repetitive sampling and determine its control constants. The in-control and the out-of-control average run lengths are derived and tabulated according to various process shifts. The proposed control chart indicates the out-of-control process more quickly than the existing control chart for small shifts.
