Research On Decision Support System For Ship Floating State Ajustment Based On 3D Model

Nowadays,due to the more advanced guided weapons,the ship is attacked and the probability of damaged ship compartment is significantly higher than that in the past.Once the ship is damaged,it will have a negative effect on the floating state and stability which weakens the ship's vitality and combat capability.At this time,we need to make rapid judgments on the floating state and stability of the ship and design correct and effective adjustment programs.The practice shows that with the rapid changes of battlefield environment and situation in maritime war,people's subjective judgment only depending on the decisions is not able to quickly find the effective optimal scheme.Even sometimes people make the wrong decision,and it is difficult to meet the decision-making needs of emergency response.Therefore,the research on Decision Support System for ship floating state adjustment are of great significance.The main contents of this paper are:(1)According to the pattern of the real ship the model is constructed by the SolidWorks 2010,and the cabin is modeled according to the general arrangement plan of the real ship.(2)Applying Visual Basic 6.0 to dock the API(Application Programming Interface)of SolidWorks 2010,The calculation of ship's three-dimensional model is calculated by computer programming language.(3)Using Microsoft Access database to store data of ship floating state and stability calculation.Using the ADO of Visual Basic 6.0 and some controls like Datagrid,it can achieve the call,query,display and modification of database.(4)The calculation method of floating state stability based on ship 3D model is analyzed.Visual Basic 6.0 is used to compile a calculation model related to the stability of the floating state.(5)The basic principle of adjusting the floating state and stability of the tank is put forward.And the calculation method of variable load is analyzed.(6)Through the AHP(analytic hierarchy process)method to carry on comprehensive comparison of floating state adjustment schemes,Select the optimal floating state adjustment scheme.(7)Integrate all of the above database and model base,and design the Decision Support System for ship floating state adjustment.
