Study On Quantitative Assessment Of Decision-making For Ship's Safety Inspection

The detention rate of Port State Control in China is relative low in the Tokyo MOU. The main reason is that we are too much worry about improper detain of ship which may lead to administrative suit while we make decision on dealing with the deficiencies found in ship's safety inspection. This paper tries to study on quantitative assessment of decision-making for ship's safety inspection by using the way of combining qualitative analysis with quantitative analysis. According to the theory of safety assessment, the items in ship's safety inspection are analyzed, three types are concluded and the system of assessing indicators is established for the items of accumulative deficiencies which would lead to detention. The tools of AHP systematic analysis and the mathematical methods of fuzzy inference are applied in this study to establish a model of result assessment of ship's safety inspection to evaluate the decision-making for ship's safety inspection synthetically, and it has been tested in actual case. The result of testing is in accordance with the actual case. The model can provide help for ship's safety inspectors while they are dealing with the found deficiencies, and officers at all different levels in maritime safety administration while they are making decision on detention of a ship. It is hopefully that this basic applying study would have contribution to improving the level of ship's safety inspection in China.
