Alarm management becomes more and more necessary as the complexity and size of manufacturing systems increases . A lot of the need for alarm management also arises because alarms can be configured on a DCS at nearly zero incremental cost , whereas in the past on physical control panel systems that consisted of individual pneumatic or electronic analogue instruments , each alarm required expenditure and control panel area , so more thought usually went into the need for an alarm . Numerous disasters such as Three Mile Island , Chernobyl accident and the '' Deepwater Horizon '' have established a clear need for alarm management
