Development Of Intelligent System For Ship’s Principal Particulars Design

Determination of a ship’s principal particulars is one of the mostessential and basic parts during ship design. It is a linear programmingproblem which requires overall consideration of the complex shipsystem. Computer Aided Design (CAD) is an effective design tool inship engineering. But it’s still very hard for a compute to solve thisproblem because it is usually solved artificially. The existing ship CADsystems limit the flexibility during design, since the codes of CADprogram is fixed and single.To satisfy the principle and characteristics of ship engineering, anew CAD program is coded in a different view point and based on anew mentality. On one hand, the program heightens designerengagement and importance in the design process and provides a moreflexible way for the communion between man and machine. Designercan build design model more naturally in the program and the custommade model that includes design goals, constraints, and calculationmethods can make the model more realistic. On the other hand, thesystem brings the experiential knowledge into computer usingintelligent method, so the computer can solve the ship design problem which is hard to quantization based on experiences. The intelligentmethod makes experiences of engineers still be the essential parts duringcomputer aided ship design.Base on the thoughts mentioned above, a CAD software isdeveloped. The software integrates a line design software FREE!shipand includes modules for hydrostatic, resistance and other performancecalculation. At last, an example of ship design proves the applicabilityof the program in ship engineering.
