The Research On Stranded Ships Refloating Engineering Auxiliary Decision System

The research on Stranded Ships Refloating Engineering Auxiliary decision system is of great value in plan design and making decision for naval salvage group.According to the fact of naval salvage group's stranded ships refloating engineering, the structure and function of Stranded Ships Refloating Engineering Auxiliary decision system was defined, and the Auxiliary decision model was also established in this paper. System model involved refloating plan design program, engineering calculation model and plan evaluatation model. The research on refloating plan design program was on basis of summarizing salvage group's experience in past years. On the research of refloating engineering calculation model, the present absent calculation method of stranded ships turning and refloating resistance was mostly lucubrated, the calculation formula of stranded ships turning and refloating resistance was deduced. Application analytical hierarchy process in refloating plan evaluating, the result was inosculate to Engineering experience.The research on the calculation method of stranded ships turning and refloating resistance and refloating plan evaluatation model was of definite theoretic value. Stranded Ships Refloating Engineering Auxiliary decision system model was provided with rather practicability and maneuverability.
