Since the 1990s , the world economy is booming international trade is increasing , which makes the container liner shipping in the rapid development of business and bring vitality to the shipping community . According to statistics about 80 % of the international cargo by sea . When the economic situation is good , the major shipping companies to expand business scale and increase the profitability of the business , and continue to custom-made new ship or lease of a ship , additional routes , to absorb the supply , which makes a significant rise in the number of the ship . Global economic crisis broke out in the second half of 2007 , so that the international trade has been hit hard , the shipping industry in the doldrums , many shipping companies to absorb less than adequate cargo , this occurs excess capacity , and slow exit mechanism plus the shipping industry , This might bring no small risk to shipping companies . Routes with boat fleet transport economic benefits related to the fleet overall structure optimization , thereby affecting the competitiveness of enterprises , reasonable shipping arrangement is particularly important for shipping companies . Large shipping companies all face the reality and to get involved in this study . The shipping companies must be comprehensive , in-depth analysis of the reasonableness of the operating system on the organization of the ship to make the ship to maximize its effectiveness . Most shipping companies or according to plan long-term work experience for capacity on the route configured , the lack of scientific basis , will be difficult to ensure the correctness of the shipping arrangement . In this paper, shipping economics and maritime business management theory and other theories as the theoretical basis of the liner shipping arrangement . On the basis of previous studies on existing routes with boats linear programming model analysis and improvement , establish a reasonable route optimization model with the ship . After , depending on the characteristics of the shipping arrangement , designed the simulated annealing algorithm , and has a good example authentication algorithm robustness , the better local optimal solution can be found within a reasonable computation time , even global best optimal solution .
