Connected facility location problems combine cost-efficient facility placement (including cheap client-to-facility-connection) with the requirement to connect the facilities among each other. Such network design problems arise, e.g., in telecommunication applications where networks consist of a central core and local clients that have to be connected to it. In practice, reliability of the core ...

This paper presents a study that characterizes, formulates, and solves the reverse logistic network design. A Mixed Linear Program model is formulated that systematically minimizes reverse logistics operating costs for the strategic problem facility location of collection sites, cannibalization and recycling. The facility location is a central issue of the logistics networks. In this paper we a...

Load distribution is commonly recognized as a useful technique to improve the performance of a distributed system. Much of the previous work on load distribution is performed in the context of process based operating systems executing on autonomous workstations. In this thesis we examine load distribution in the context of ne-grained object based operating systems and describe the design and im...

This paper explores the design of “super-fast” distributed algorithms in settings in which bandwidth constraints impose severe restrictions on the volume of information that can quickly reach an individual node. As a starting point of our exploration, we consider networks of diameter one (i.e., cliques) so as to focus on bandwidth constraints only and avoid penalties imposed by network distance...

Connected Facility Location (ConFL) is a problem that combines network design and facility location aspects: given a set of customers, a set of potential facility locations and some inter-connection nodes, ConFL searches for the minimum-cost way of assigning each customer to exactly one open facility, and connecting the open facilities via a Steiner tree. The costs needed for building the Stein...

The unequal area facility layout problem has been studied using several distance metrics in the objective function, most commonly rectilinear distance and Euclidean distance between departmental centroids. This paper modifies the distance metric to consider material travel along the perimeter of the departments to and from input/output locations. This perimeter distance metric is used in the ob...

voltage control is one of the imperative issues in the smart distribution control system. while traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. with using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...

in this paper, a new model is proposed for the integrated logistics network designing problem. in many research papers in this area, it is assumed that there is only one option for the capacity of each facility in the network. however, this is not a realistic assumption because generally there may be many possible options for the capacity of the facility that is being established. usually the c...
