Abstract

Determination of ship machinery performance and its maintenance management scheme using MARKOV process analysis K. B. Artana and K. Ishida Department of Electro Mechanical and Energy Engineering, Kobe University of Mercantile Marine, Japan Abstract The objective of this paper is to describe and evaluate a scheme of engineering- economic analysis in determining a ship's machinery performance and its maintenance management scheme. The machinery performance is assessed by means of Continuous MARKOV analysis by obtaining its performance indices such as Reliability, Availability and Maintainability (RAM). Since the problem of ship and marine machinery operation can be represented as a multi-variable and multi-constraint engineering-economic problem, then a multiple constraints optimization scheme can be utilized to find the most appropriate maintenance management scheme. The main engine cooling system of a ship is taken as the object of the study case. It is conclusively found that this kind
