Service-Constrained Network Design Problems

چکیده
Several practical instances of network design problems often require the network to satisfy multiple constraints. In this paper, we focus on the following problem (and its variants): nd a low-cost network, under one cost function, that services every node in the graph, under another cost function, (i.e., every node of the graph is within a prespeciied distance from the network). This study has important applications to the problems of optical network design and the eecient maintenance of distributed databases. We utilize the framework developed in Marathe et al. 1995] to formulate these problems as bicriteria network design problems, and present approximation algorithms for a class of service-constrained network design problems.

Reliable hub-and-spoke network design problems under uncertainty through multi-objective programming
HLP (hub location problem) tries to find locations of hub facilities and assignment of nodes to extended facilities. Hubs are facilities to collect, arrange, and distribute commodities in telecommunication networks, cargo delivery systems, etc. Hubs are very crucial and their inaccessibility impresses on network whole levels. In this paper, first, total reliability of the network is defined bas...
متن کاملConstrained Multi-Objective Optimization Problems in Mechanical Engineering Design Using Bees Algorithm
Many real-world search and optimization problems involve inequality and/or equality constraints and are thus posed as constrained optimization problems. In trying to solve constrained optimization problems using classical optimization methods, this paper presents a Multi-Objective Bees Algorithm (MOBA) for solving the multi-objective optimal of mechanical engineering problems design. In the pre...
متن کاملInterdependent Security Game Design over Constrained Linear Influence Networks
In today's highly interconnected networks, security of the entities are often interdependent. This means security decisions of the agents are not only influenced by their own costs and constraints, but also are affected by their neighbors’ decisions. Game theory provides a rich set of tools to analyze such influence networks. In the game model, players try to maximize their utilities through se...
متن کاملBudget Constrained Minimum Cost Connected Medians
Several practical instances of network design and location theory problems require the network to satisfy multiple constraints. In this paper, we study a graph-theoretic problem that aims to simultaneously address a network design task and a location-theoretic constraint. The Budget Constrained Connected Median Problem is the following: We are given an undirected graph G = (V;E) with two differ...
متن کاملAn efficient one-layer recurrent neural network for solving a class of nonsmooth optimization problems
Constrained optimization problems have a wide range of applications in science, economics, and engineering. In this paper, a neural network model is proposed to solve a class of nonsmooth constrained optimization problems with a nonsmooth convex objective function subject to nonlinear inequality and affine equality constraints. It is a one-layer non-penalty recurrent neural network based on the...
