在枢纽式航线网络蓬勃发展的背景下，蛛网式航线网络作为一种新兴的网络结构，它的出现引起了国内外的广泛关注.针对蛛网式航线网络的要素进行了深入分析，从减少非必要的中转的角度出发，提出旅客时间价值系数的概念，将航空公司的运输成本和旅客时间价值作为总效用，设计出蛛网式航线网络效用模型.通过使用该模型，可以设计出蛛网式航线网络并分析其每条航线的竞争力.基于该模型对于每条起讫节点流（Origin Destination, OD流）可分解的性质，提出了基于效用理论的最短路径算法,利用我国15城市数据建立了蛛网式航线网络模型实例.求解的结果表明，旅客时间价值系数对蛛网式航线网络以及蛛网式航线网络的竞争力的影响.

Design of Spider WebAirline Network Model

The spider web airline network,a new airline network,has attracted international and domestic scholars’ attentions.It is different from the current mainstream hub-and-spoke airline network in terms of network structure and operating style.After analyzing the spider web airline network considering minimizing unnecessary transfer,this paper proposes a concept of passengers’ value of travel time.Furthermore,a spider web airline network utility model is developed using a total utility which combines transport cost and passenger’s cost of travel time.One advantage of this model is that it can decompose the Origin-Destination(OD) flow.Based on this feature,a shortest utility path algorithm is presented to solve the problem.An empirical study is conducted based on a spider web airline network using the data from 15 Chinese major metropolitan airports.The empirical study demonstrates the advantages of spider web airline network.It also indicates that passengers’ value of travel time has impacts on the spider web airline network.
