Profit-Function of Two Similar Warm Standby Navy Ship System Subject to Failure due to Struck with Iceberg and Collision with Oil Tanker.
Notable disasters – The sinking of RMS Titanic in 1912, with 1,517 fatalities, is probably the most famous shipwreck, but not the biggest in terms of life lost. The wartime sinking of the Wilhelm Gustloff in January 1945 in World War II by a Soviet Navy submarine, with an estimated loss of about 9,400 people, remains the greatest maritime disaster ever. In peacetime, the 1987 loss of the ferry Doña Paz, with an estimated 4,386 dead, is the largest non-military loss recorded. In this paper we have taken failure due to struck with iceberg and collision with oil tanker. When the main unit fails then warm standby system becomes operative. Failure due to collision with oil tanker cannot occur simultaneously in both the units and after failure the unit undergoes Type-I or Type-II or Type-III repair facility immediately. Applying the regenerative point technique with renewal process theory the various reliability parameters MTSF, Availability, Busy period, Benefit-Function analysis have been evaluated.
