We propose a novel hub location model that jointly eliminates some of the traditional assumptions on structure network and discount as result economies scale in an effort to better reflect real-world logistics transportation systems. Our extends literature various facets: instead connecting nonhub nodes directly nodes, we consider routes with stopovers; pairs hubs directly, design can visit sev...

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...

The construction of hydrogen refueling stations is an important part the promotion fuel cell vehicles. In this paper, a multi-period station location model presented that can be applied to planning and infrastructures. Based on demand passenger cars commercial vehicles, calculates each zone by weighting method according population, economic level education level. Then, period calculated using g...

The increasing demand for multimodal freight transportation makes the expansion of new secondary hubs necessary. carbon tax has also received attention from various sectors due to development requirements green transportation. Therefore, this study proposed a transport hub location problem, where emissions are specifically considered achieve strategic planning. A mixed integer non-linear progra...

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...

This paper investigates a multi-period rectilinear distance 1-center location problem considering a line-shaped barrier, in which the starting point of the barrier follows the uniform distribution function. In addition, the existing points are sensitive to demands and locations. The purpose of the presented model is to minimize the maximum barrier distance from the new facility to the existing ...

This paper proposes a discrete capacitated covering location-allocation model for pharmaceutical centers. In the presented model, two objectives are considered; the first one is minimization of costs and the second one try to maximize customer satisfaction by definition of social justice. Social justice in the model means that we consider customers satisfaction by using distance. the introduced...
