We consider the problem of bandwidth allocation in a substrate network as an optimization problem for the aggregate utility of multiple applications with diverse requirements and describe a simulation scheme for dynamically adaptive bandwidth allocation protocols. The proposed simulation model based on Coloured Petri Nets (CPN) is realized using CPN Tools. Keywords—Bandwidth Allocation Problem,...

Decoupling the uplink and downlink user association improves the throughput of heterogeneous networks (HetNets) and balances the traffic load of macro- and small- base stations. Recently, fiber-wireless HetNets (FiWi-HetNets) have been considered as viable solutions for access networks. To improve the accuracy of user association and resource allocation algorithms in FiWi-HetNets, the capacity ...

This paper presents an optimization-based approach for determining how plant feedstocks should be allocated to storage when there are fewer storage vessels than feedstocks. It is assumed here that material from the storage vessels will be subsequently blended for processing in downstream processes. The objective of the feedstock allocation strategy is chosen to ensure maximum flexibility for do...

The allocation of virtual machines (VMs) to physical machines in data centers is a key optimization problem for cloud service providers. It is well known that the VM allocation problem contains the classic bin packing problem as special case. This paper investigates to what extent the existing approximability results on bin packing and its generalizations can be applied to the VM allocation pro...

With the general awareness of energy and environmental issues in whole society, issue greenhouse gas emission reduction has gradually become focus attention. Ocean transport undertakes more than 90% world's cargo transportation also produces a large amount carbon dioxide. In order to achieve shipping industry, June 2012, ECOFIN proposed impose Maritime Carbon Tax, which will increase operating ...

Population games have become a powerful tool for solving resource-allocation problems in a distributed manner, and for the design of non-centralized optimization-based controllers. The aim of this paper is to illustrate the advantages of two recently introduced population-game approaches in comparison to other classical optimization methods. More specifically, the discussion is mainly devoted t...

one of the most important problems in the system reliability optimization is redundancy allocation problem that has been studied in different system configurations. k-out-of-n structure is a general system configuration and offers enhanced capabilities for analyzing more design problems. hence, in this paper, the redundancy allocation problem of k-out-of-n systems is studied. in the most previo...
