As interlibrary loan (ILL) becomes an increasingly used resource sharing mechanism for the exchange of books and periodicals, libraries have embraced new technologies to better manage ILL activities. While many efficiencies have been gained through the use of computers and telecommunication networks, the proliferation of telecommunication options, ILL systems and non-standard message formats ha...

The purpose of this paper is to formally describe new optimization models for telecommunication networks with distributed processing. Modern distributed networks put more focus on the processing of information and less on the actual transportation of data than we are traditionally used to in telecommunications. This paper introduces new approaches for modelling decision support at operational, ...

In this technical report analytical models of wireless channels are presented. The report addresses the reader interested in the various effects, which lead to the well known, unreliable and stochastic nature of wireless channels. The report is composed from various other books, reports and so, due to the reason that a comprehensive, but still easy understandable discussion of the matter for en...

The current telecommunications environment is characterised by the highly interconnected mesh of networks ooering various advanced services, and the complexity of software and telecommunication protocols is constantly increasing. This high level of interconnectivity, coupled with the sophisticated technology, creates an unstable equilibrium and imposes a threat of malfunction, with the possibil...

In this paper, we focus on the capacitated survivable network design problem when the survivability is expressed in terms of rerouting techniques. We propose an approach that permits to achieve optimal solution in reasonable time. Our approach uses both Benders decomposition and a cutting plane approach to reduce the high dimensionality of the problem. Some numerical results are also presented.

We follow the vision of end-systems being connected mainly via wireless technologies to an optical communication infrastructure. We believe that the communication will be based on multimediasupport enhanced Internet, with quality of service support being achieved by segregation rather than reservation. In addition to wireless access also nomadicity and mobility will have to be increasingly supp...
