This paper describes the way a multi-item, multi-plant Lot-Sizing problem with transfer costs and capacities may be reformulated according to a multi-commodity flow formalism, and decomposed, through Lagrangean Relaxation, into a master Facility Location problem and a slave Minimal Cost Multi-commodity Flow problem. This decomposition framework gives rise in a natural way to the design of a relax/project...
Developing techniques for optimal allocation of limited resources to a set of activities has received increasing attention in recent years. In this paper, an efficient resource allocation scheme based on particle swarm optimization (PSO) is developed. Different from many existing evolutionary algorithms for solving resource allocation problems (RAPs), this PSO algorithm incorporates a novel representation...
In this paper a BISR architecture for embedded memories is presented. The proposed scheme utilises a multiple bank cache-like memory for repairs. Statistical analysis is used for minimisation of the total resources required to achieve a very high fault coverage. Simulation results show that the proposed BISR scheme is characterised by high efficiency and low area overhead, even for high defect densities...
