Stratified parallel chaos algorithm on synthesized optimization for seagoing performance of draft-limited inland ship

Design and analysis on synthesized optimization for ship seagoing performance is a task attaches great importance.Based on stratified theory,parallel algorithm and chaos algorithm,a mathematic model of performance synthesized optimization for draft-limited inland ship has been built up,a stratified parallel chaos integrated algorithm to resolve this problem based on sensitive viable subsection has been developed and a interface-friendly VC software has been worked out.Then,the inheritance algorithm,chaos algorithm,parallel chaos algorithm and stratified parallel chaos algorithm have been made a lot of optimized calculation on synthesized optimization for resistance,propulsion and maneuverability of a draft-limited inland ship.On summary,this synthesized algorithm is reliable and efficient to establish the basis for design on synthesized good ship type of draft-limited large inland ship.
