Fuzzy-chaos algorithm and its study on application of integrate optimization of ship performance or structural characteristics

In this paper,the fuzzy-chaos algorithm is proposed,which is composed of the fuzzy genetic algorithm of bound search and the chaos algorithm.This algorithm is applied to optimize,calculate and analyze large-scale ship performance or structural characteristics.Establishing the integrate optimization mathematical model which form is the linear addition power average sum of all object functions,programming the calculation software and carrying on a lot of comparison calculation.The calculation results show that these optimization methods and the calculation software have friendly interface,good dependability and higher calculation efficiency;this optimization method and the calculation software have practicability and applied to integrally optimize the ship performance or structural characteristics is feasible.To large-scale ship project or their primary design it is worth using.
