Revenue allocation model for port cooperation with considering of risk and contribution

In order to effectively stimulate the port cooperation and achieve the improvement of all individual ports' benefit,the contribution to cooperation and the risk in cooperation were considered,a nonlinear programming model was developed to design revenue allocation scheme in port cooperation according to the principles of mutual benefits,contribution-income matching,risk-income matching,a numerical example was given to demonstrate the effectiveness of the model. Analysis result shows that the individual port revenue obtained by the proposed model is greater than that when individual port operates separately,and the sum of individual port revenue is equal to the total revenue of three port cooperations,so the model can bring high economic benefit and realize the reasonable distribution of economic benefit. 6 tAbs,2 figs,12 refs.
