| TITLE | Surveillance Methods For Detecting A Change |
The distribution of a sequence of independent observations may remain the same over time but the possibility exists for a change to another distribution at some unknown time due to the malfunction of the machine etc. and a surveillance of the process is required so that the process could be stopped as soon as possible. The delay in detecting the change will depend on the method used for surveillance. For normal distribution, we describe these methods and compare them. A simple method for obtaining the control boundary where the procedure is stopped to check for the change, if any, is also given.
