Generation Mode Analysis of General Quality Characteristic of Ship Power System

Abstract

General quality characteristic is a key parameter reflecting the operation quality of a ship power system. The analysis of the generation mode of the general quality characteristic is an effective mean to improve the comprehensive performance of the ship power system. In this paper, firstly, 6 main factors and 18 sub-factors of the general quality characteristic are given for the ship power system. Secondly, the quantitative assessment models of the main factor and the sub-factors are established based on fuzzy mathematics theory. Thirdly, the dynamic characteristics between the influencing factors and between the main factors and the general quality characteristic are analyzed based on Markov stochastic process model. Finally, the calculation results show that increasing a certain main factor by 10% can improve the general quality characteristic of the ship power system by 3% to 4%. However, the sensitivity of the general quality characteristic to the main factors varies. Improving the maintainability and environmental worthiness of ship power system is an effective method to improve its general quality characteristic.
