Topological optimization of computer network expansion with reliability constraint

Topological Optimization of a Communication Network Subject to a Reliability Constraint

Conclusions This paper considers network topological optimization with a reliability constraint. The objective is to find the topological layout of links, a t a minimal cost, under the constraint that the network reliability is not less than a given level of system reliability. A decomposition method, based on branch & bound, is used for solving the problem. In order to speed-up the procedure, ...

A Noisy Chaotic Neural Network Approach to Topological Optimization of a Communication Network with Reliability Constraints

Network topological optimization in communication network is to find the topological layout of network links with the minimal cost under the constraint that all-terminal reliability of network is not less than a given level of system reliability. The all-terminal reliability is defined as the probability that every pair of nodes in the network can communicate with each other. The topological op...

Evaluation of Network Reliability for a Computer Network Subject to a Budget Constraint

This paper constructs a multistate flow network composed of multistate edges to model a computer network. Each edge has lead time, capacity, and cost parameters. Therefore, the minimum transmission time through a single path is not a fixed number. Under the transmission protocol that the data are sent through p (p ≥ 2) minimal paths simultaneously, the minimum transmission time is also stochast...

Bi-objective optimization of a blood supply chain network with reliability of blood centers

This paper presents a multi-periodic, multi-echelon blood supply chain network consisting of blood donors, mobile collection units, local blood centers, main blood centers and demand points in which the local and main blood centers are subject to random failure in dispatching blood products to demand points. The problem has two objectives including minimization of the total chain costs and maxi...
