In this paper we propose an efficient method for this problem, based on a Lagrangian heuristic within a branch-and-bound framework. The Lagrangian heuristic uses a Lagrangian relaxation to obtain ...

Traditional systems development approaches delay the delivery of tangible information system capabilities to users (i.e., query capabilities and decision support models, etc.) until the last stages of ...
