Reliability-Based Warship Readiness Analysis Using the Bayesian Network Method

Warships are one of the main tools of the national defense system used to defend a country's territorial waters. Regarding the constituent systems of warships, there is an interrelated relationship between one system and another to form larger and more complex systems including propulsion system, electrical system, navigation system, communication system, weapon system, and so on. The complexity is largely due to the demands of self-supporting capability in a marine environment that is not easily habitable, coupled with the ability to carry out offensive and defensive actions in a sea battle. Considering the function of warships as the main tool of the national defense system, the condition of these ships must always prioritize elements of shipping safety and security while carrying out operations at sea. In addition, warships should also have weaponry and sensor equipment as offensive and defensive tools. One of the factors to support the safety and security of sea transportation is the seaworthiness of the ship. In this study, the author made an assessment to determine the reliability-based warship material readiness. The data were compiled and processed using the Bayesian network method, and the results are applied to determine the warship readiness.
