The Study On Quay Allocation In Container Terminal Under The Constraint Condition Of Carbon Emission

With the development of the industrialization, large amount of greenhouse gas is discharged which leads to the global temperature rise and climate change, it has serious harms to the human survival environment and health safety, so the low carbon economic development model has been advocated all over the world. With the prosperity of container shipping, the port enterprises became large energy consumption units. Quay crane which consumes a lot of electrical energy is one of the majoy energy-consuming equipment as the main handling equipment in container terminal. With the development of large container vessels, the trend of large scale and high speed has become more and more obvious, so it is necessary to improve adaptability and operating efficiency of container terminal. However, larger and more advanced quay crane consumes more electrical energy and produces more carbon emissions, therefore, how to reduce carbon emissions during optimizing quay crane allocation has become an important issue to be resolved.On the basis of researching the calculation extent and method of container terminal carbon emission, we set the sum of minimum ship mooring charges incurred and berth idle costs as the the objective function which is constrained by CO2emitted by handling unit to present a programming model of quay crane allocation in this paper.Meanwhile, the influence of CO2emission constraint and different quening theory models on the optimization results are analyzed by comparing the optimization results of quay crane allocation after considering the constraint condition of the CO2with the result before that. It shows that we can reduce the CO2emission by bridge reconfiguration.Also, we optimize the sensibility by comparing the optimization results of quay crane allocation that calculated by different quening theory models. Finally, it proves that the constraint condition of CO2emitted would affect the primary quay crane allocation, and the CO2emitted by handling unit throughput can be reduced by reallocating the quay cranes. Meanwhile, it also indicates that the optimization results of quay crane allocation are different with the different quening theory models, when using the quay crane allocation programming model, it must choose the suitable quening theory model according to the practical problem.
