1 Loss System For a background review, I started the summer vacation scholorship by looking at loss systems. In a telecommunication context, this means that a new coming call is blocked (or lost) if there is no free circuits for that call. First of all, I made myself familiar with the notations. In a loss system, let C be the total number of circuits available, n be the number of circuits in us...

I. DEFINITION OF PROBLEM In current conditions of dynamic development of various approaches of the analysis and synthesis of the telecommunication networks integrated into information and telecommunication technology [1-5] there are questions of elaboration and application of the general methods of ensuring service quality based on allocation of separate classes of quality and realization of ma...

Complex environments for ATM based telecommunication services assume high availability and reliability of the network resources as well as the services. In order to reduce the cost of building and maintaining wide area ATM networks, efficient and cost-effective resource management techniques are needed to avoid over-allocation of resources. This requires building a network having the intelligen...

This paper proposes an efficient algorithm to evaluate system reliability for many real-life systems such as manufacturing, telecommunication and computers systems. A multicommodity stochastic-flow network is constructed to model a manufacturing system in which each node stands for a machine station, and each arc stands for a transmission medium (shipping machine or conveyor). Four characterist...

Many real world systems (electric power, transportation, telecommunication, etc) are multistate systems composed of multistate components in which system reliability can be computed in terms reliabilities of its components. Such systems may be regarded as flow networks whose arcs (components) have independent, discrete, and multi-valued random capacities. An arc can, at different conditions, be...

For example, in an s-t reliability network evaluation, the connectivity of the network requires to use a depth-first procedure as EF [2,3]. In other cases (telecommunication networks as well as pipeline systems, computer nets, transporting systems among others) the connectivity is not a sufficient condition for an operating state and the success of the network implies that a required flow is gu...
