As a network organization type, the spider web airline network has received more attention. In this paper, we analyzed the relation between the spider web airline network and spider web, and the structure of spider web airline network, built the assignment model of the spider web airline network,and investigated the economics concerned.展开更多

In this work, firstly, we assume cities as sites, flight between two cities as an edge between two sites, and build a dynamic evolution model for airline networks by improving the BA model, in which the conception of attractiveness plays a decisive role in the course of evolution of the networks. To this end, we discuss whether the attractiveness depends on the site label s or not separately, finally we obtain analytic degree distribution. As a result, if the attractiveness of a site is independent of the degree distribution of sites, which will follow the double power law, otherwise, it will be scale-free. Moreover, degree distribution depends on the parameters of the models, and some parameters aye more sensitive than others.展开更多

文摘In airline revenue management,after differentiating products on each itinerary according to various restrictions,management needs to set the prices for the products.A deterministic joint pricing and seat allocation model is proposed.It is reduced to a separable concave programming problem and thus readily solvable.Focusing on a special hub-to-hub airline network,monotonicity of the pricing decisions is explored.Using a nonlinear primal–dual technique,it is shown that some itineraries’optimal prices are decreasing,while some other itineraries’optimal prices are increasing with a capacity change in either a side leg or the middle leg.Such structural properties add important managerial insights into the pricing model for revenue managers in an airline company.
