Fitness BA Model of Container Shipping Network under the Ecological Vision
摘要
Abstract
The container shipping network is port systems and the spatial organization of routes , which evolution is a complex social , economic and historical integration process .According to the evolution dynamic mechanism based on the ecology metaphor , the characteristics of size limit and dynamic development of container shipping network in reality have been fully considered .Furthermore , the five mechanisms , named node step , node dele-tion, preferential attachment , anti-preferential deletion and rewiring are proposed based on “survival of the fit-test”.Since the adaptability indexes for port hinterland economy , port throughput and port location are designed to measure the fitness of port node , a fitness BA model is put forward .Then , the degree distribution is calculated by theoretical derivation and numerical simulation .The results show that (1) the degree distribution depends on not only the degree of port nodes , but also the fitness function of port nodes;( 2 ) the fitness BA model owns a power-law degree distribution with an exponent γ=1+1/β;(3)“first-mover-wins” will be present if the fitness of each port node is all equal , while“fit-gets-richer” will appear if the fitness of each port node is not completely equal.关键词
