Research on the Evalution Method of Surface Warship Low Levels Maintenance Time

Abstract

The in-shipyard maintenance time of warship has an important influence on its navigation rate, service life and repair engineering profit during its whole life cycle. On the basis of combing and analyzing the engineering practice of warship’s levels maintenance at home and abroad, a method for in-shipyard maintenance time evaluating based on the key repair path was put forward in this paper, as which divided the surface warship low levels maintenance into 9 engineering stages from the time sequence relationship. At the same time, the levels maintenance time evaluation model and the basic maintenance time database of the surface warships were established basing above. The correctness of this evaluation method was verified by comparing the maintenance time evaluation results with the real maintenance data, which could provide an important technical basis for the weapon management department to make use and maintenance decisions.
