| Abstract: | Focusing on the research of method of optimal voyage selection to meet the specific needs of bulk cargo shipping,this paper analyzes how three factor of cargo,vessel and port influence the decision qualitatively and quantitatively.Then based on the knapsack problem,we create the corresponding optimal voyage selection model and define reasonable constraint rules to accelerate getting final results. |
