The Research On The Problem Of Container Shipping Lines Considering Speed

The shipping market is greatly influenced by the world economy and trade,and the shipping market also presents different development under different trade backgrounds.After the 2008 economic crisis,the shipping market continued to slump,container capacity was significantly over,the competition between liner companies increasingly fierce.For the container liner business,because the route once identified,can not easily change and adjust the route;the other hand,the large-scale development of the ship also led to the fixed cost of the ship,operating costs and so on,so how in the liner business has It is very important to carry out the scientific and rational configuration of the ship with different ship type,and the reasonable route matching scheme can not only reduce the operating cost of the fleet enterprise fleet,but also enhance the service level and market competitiveness of the enterprise.Many studies on liner shipping are considered constant,and the speed of the speed not only affects the fuel costs but also affect the number of shipments,with the market changes in the liner business will be based on their own operating conditions to adjust the speed,thus In this case,the speed of the route as a variable into the liner liner model,that is,considering the variable speed of the liner company's distribution problem.In addition,the problem of container liner distribution is affected by the market environment.In this paper,the model is established for the two kinds of shipping markets,such as market economy and market downturn,and the time penalty cost brought by the decrease of the speed Considering the situation of the current market downturn,considering the number of ships on the route,the number of idle and the speed of the ship's operation,the mathematical model is established based on the minimum target cost,and the optimal configuration is obtained by LINGO software The results of the study also show that the effective reduction of the speed in the market downturn can not only reduce the fleet cost but also absorb more idle capacity,thus validating the effectiveness of the model.
