k-out-of-nシステムによる舶用推進システムの解析 Analysis of Marine Propulsion System Based on K-out-of-n System
Before, "High-Reliable Ship" was studied, and at that time the term "High-Reliable" might give the marine engineers such imagination that the marine propulsion system was operating without break down and free from maintenance. However, in order to obtain and keep the reliability of marine power plant, it has been very cleared how important it is to reconstruct the method for design and maintainance on the power generator plant for marine propulsion. For example, the electric propulsion system is one of the typical plants realized through new design method which has been appeared recently in the world.<BR>The object of this paper is to propose a unified power plant and then to analyze it through the k-out-of-n system method. Here the power generator plant is unified and it provides the necessary power for ship navigation, that is the propulsion power, necessity power for operating subsystems and crew life on board.<BR>First, the concept of a k-out-of-n system method is presented and then using it, necessary results for analyzing the new power plant are introduced theoretically. Next, the obtained results are applied to the new power plant using the data which can be obtained from the field of the marine power plant. Finally, the analytical method based on the k-out-of-n system is shown to be extremely useful one by illustrating the results, and a new power plant proposed newly is very effective from the viewpoint of reliability.
