Air freight network is one of the important means to improve the competitiveness of express enterprises. This paper establishes the model from two aspects, hub location decisions and hub number decisions, with the goal to achieve the lowest air freight network cost, based on the “hub-spoke” theory. Then, computes the cost of different number of hubs, and uses super-efficiency DEA model to decid...
BACKGROUND AND PURPOSE Enrollment into acute stroke clinical trials is limited to experienced tertiary centers with emergency research infrastructure. Feasibility of remote enrollment via telemedicine into an acute thrombolytic clinical trial has never been demonstrated. METHODS Using telemedicine, our hub stroke research center partnered with two spoke community hospitals to jointly particip...
Two competitors, a Leader and a Follower, are sequentially creating their hub and spoke networks to attract customers in a market where prices have fixed markups. Each competitor wants to maximize his profit, rather than a market share. Demand is split according to the logit model. The goal is to find the optimal hub and spoke topology for the Leader. We represent this Stackelberg game as a non...
Abstract. We consider a single allocation hub-and-spoke network design problem which allocates each non-hub node to exactly one of given hub nodes so as to minimize the total transportation cost. This paper deals with a case in which the hubs are located in a cycle, which is called a cycle-star hub network design problem. The problem is essentially equivalent to a cycle-metric labeling problem....
