in this paper, we study the problem of integrated capacitated hub location problem and seat inventory control considering concept and techniques of revenue management. we consider an airline company maximizes its revenue by utilizing the best network topology and providing proper booking limits for all itineraries and fare classes. the transportation system arises in the form of a star/star net...

We investigate a variant of the many-to-many hub location-routing problem which consists in partitioning the set of nodes of a graph into routes containing exactly one hub each, and determining an extra route interconnecting all hubs. A variable neighborhood descent with neighborhood structures based on remove/add, swap and exchange moves nested with routing and location operations is used as a...

In this paper, we introduce a new hub-and-spoke structure for service networks based on round-trips as practiced by some transport providers. This problem is variant of Uncapacitated Hub Location Problem wherein the spoke nodes allocated to hub node form (cycles) starting from and ending node. motivated two real-life practices in logistics runaway connections with their associated economies sca...

We consider the hub location problem, where p hubs are chosen from a given set of nodes, each nonhub node is connected to exactly one hub and each hub is connected to a central hub. Links are installed on the arcs of the resulting network to route the traffic. The aim is to find the hub locations and the connections to minimize the link installation cost. We propose two formulations and a heuri...

In this paper, we propose an extension of the uncapacitated hub location problem where potential positions hubs are not fixed in advance. Instead, they allowed to belong a region around initial discrete set nodes. We give general framework which collection, transportation, and distribution costs based on norm-based distances hub-activation setup depend only that opened but also size placed. Two...
