Number of Days Which Failure Occurs

Count Days a Reservoir Overflows

Description

Count Days in which an Overflow Occurs

Assume there is a reservoir with a stream flowing directly into the reservoir at some randomly changing rate. Water continuously evaporates from the water surface of the reservoir. When the volume in the reservoir reaches its upper bound, the reservoir overflows at a rate equal to the net inflow. An overflow is considered to be a failure of the system and this event must be recorded and tallied to evaluate the system reliability.

This model counts the number of days in which some failure occurs. A failure event is defined as an overflow occurrence for any duration within a single day. An overflow that lasts for 1 hour is counted the same as an overflow that lasts for 24 hours. Also, an overflow that occurs repeatedly during a single day is counted the same as an overflow that occurs one time during a day.
