Container Ship's Structure Optimum Design Method Based On Ant Colony Algorithm

Along with the fast growth of the global trade, the container transportation with the characteristic of high efficiency and convenience gradually seizes the market and becomes the mainstream of the shipping industry. This paper, pursues minimum weight, set up the design variables deciding weight, divides the container's holds into cells along the ship's length and calculates stress distributing to check safety by bow and rear boundary conditions.This paper provides the new global optimization-the improved Ant Colony Algorithm. This algorithm has strong searching ability and high precision. Also it can be easily programmed and convenient for transplanting. So it has the widespread serviceability as well as the good development prospect. The MATLAB program about the improved Ant Colony Algorithm is modularized. These modules haven't business with each other and the modification won't influence another. The result indicates that the improved Ant Colony Algorithm can be applied in the structural optimization about ship, and we can obtain very good optimized result.
