Dynamic Fleet Planning For Ship Corporation In Uncertain Circumstance

With the integration of global economic, the rapid development of port logistics industry and construction in full swing of port city industrial park in recent years, port logistics industry and city economics interrelated and affected each other closely. How to create the mutually beneficial and win-win situation become an urgent problem to resolve, in order to achieve resource intensive and benefit maximization.This paper based on the topic of the research on collaborative development of Liaoning coastal economic zone Port Logistics and Area Economic has the significance of theoretical academic value and practical application, aiming at analyzing the level of Liaoning coastal economic zone Port Logistics and Area Economic collaborative development.Firstly, this paper defines the definition of port logistics and regional economic and qualitative analyze the collaborative relationship of port logistics and area economic. Then, On the basis of the relevant literature and according to the theory of synergetic, this paper constructs the degree measure model between port logistics and area economy. Next, using the model above, this paper calculate the synergy degree of Liaoning coastal economic zone.On the one hand, to verify the validity of the model, on the other hand to explore the joint development level of Liaoning coastal economic zone as a whole and all the port cities.The results show that the port logistics and area economic synergy measure model can fully reflect the level of the joint development of Liaoning coastal economic zone and the regional port logistics and regional economy, the study can provide a theoretical basis for the formulation of port logistics policy and urban economic development planning in Liaoning coastal economic zone.
