Network Design with Weighted Degree Constraints
In an undirected graph G = (V,E) with a weight function w : E×V → Q+, the weighted degree dw(v;E) of a vertex v is defined as ∑ {w(e, v) | e ∈ E incident with v}. In this paper, we consider a network design problem with upper-bound on weighted degree of each vertex. Inputs of the problem are an undirected graph G = (V,E) with E = E1 ∪̇ E2 ∪̇ E3, weights w1 : E1 × V → Q+, μ : E2 → Q+, ν : E3 → Q+,...
متن کاملNetwork-Design with Degree Constraints
We study several network design problems with degree constraints. For the degree-constrained 2-connected subgraph problem we obtain a factor 6 violation for the degrees with 4 approximation for the cost. This improves upon the logarithmic degree violation and no cost guarantee obtained by Feder, Motwani, and Zhu (2006). Then we consider the problem of finding an arborescence with at least k ter...
متن کاملSupply chain network design with multi- mode demand based on acceptance degree of fuzzy constraints violated
This paper designs a mathematical model for supply chain network design problem including plants, distributors and customers in fuzzy environment. Each plant and distributor has several levels capacities. A multi-mode demand strategy is considered for the customers where only one of the modes is to be selected for each customer. Considering the acceptance degree of fuzzy constraints violated, a...
متن کاملOn some network design problems with degree constraints
We study several network design problems with degree constraints. For the minimum-cost Degree-Constrained 2-Node-Connected Subgraph problem, we obtain the first non-trivial bicriteria approximation algorithm, with factor 6 violation for the degrees and a 4-approximation for the cost. This improves upon the logarithmic degree violation and no cost guarantee obtained by Feder, Motwani, and Zhu (2...
