We study the polyhedra of splittable and unsplittable single arc{set relaxations of multicommodity ow capacitated network design problems. We investigate the optimization problems over these sets and the separation and lifting problems of valid inequalities for them. In particular, we give a linear{time separation algorithm for the residual capacity inequalities 19] and show that the separation...

Abstract In this paper, the overall architecture design of platform is proposed, and data business are discussed. On basis, logistics path planning method digital collaboration including aspects demand splitting distribution vehicle spatio-temporal network, splittable model considered. Finally, simulation workshop dynamic scheduling example designed, optimization results analyzed verified. The ...

In this paper, we study the traffic management problem for multi-homed mobile networks with the objective of minimizing the overall handover cost. Two different traffic distribution modes are considered in our study: the Fractional Flow Assignment (FFA) mode which assumes the bandwidth demand from one connection is infinitely splittable and can be assigned to different wireless access networks,...

We study the polyhedra of splittable and unsplittable arc sets of multicommodity ow capac-itated network design problems. We investigate the optimization problems over these polyhedra and the separation and lifting problems of valid inequalities for them. In particular, we give a linear-time separation algorithm for the residual capacity inequalities (Magnanti et al., 1993) and show that the se...

This paper discusses the problem of allocation of constrained renewable resource to splittable activities of a single project. If the activities of stochastic projects can be split, these projects may be completed in shorter time when the available resource is constrained. It is assumed that the resource amount required to accom-plish each activity is a discrete quantity and deterministic. The ...

A promising solution to overcome the Internet ossification is network virtualization in which Internet Service Providers (ISPs) are decoupled into two tiers: service providers (SPs), and infrastructure providers (InPs). The former maintain and customize virtual network(s) to meet the service requirement of end-users, which is mapped to the physical network infrastructure that is managed and dep...

We study the existence of pure strategy Nash equilibria (PSNE) in integer–splittable weighted congestion games (ISWCGs), where agents can strategically assign different amounts of demand to different resources, but must distribute this demand in fixed-size parts. Such scenarios arise in a wide range of application domains, including job scheduling and network routing, where agents have to alloc...
