The 'Light Beam Search' approach - an overview of methodology and applications

Article Abstract:

A study was conducted to characterize the Light Beam Search (LBS) methodology and its uses. The methodology promotes an interactive evaluation of multiple-objective decision problems using samples of a large set of non-dominated points. LBS also makes use of a local preference framework, aspiration point and sampling methods. In addition, LBS supports the comparison of non-dominated points in the decision phase.

Interactive analysis of multiple-criteria project scheduling problems

Article Abstract:

An interactive approach was utilized to address a multiple-criteria project scheduling problem. The first part of the approach involves the use of the Pareto Simulated Annealing metaheuristic method to produce a large representative sample of non-dominated schedules. The second part involves conduction of interactive search over the sample with the help of the Light Beam Search procedure.

Optimization analysis for design and planning of multi-project programs

Article Abstract:

A method that employs the work breakdown structure and Dantzig-Wolfe decomposition was created to produce viable multi-project plans and schedules. The method involves utilization of deviational variables to relax some of the Dantzig-Wolfe decomposition master problem constraints. Such activity allows the application of the Dantzig-Wolfe decomposition technique in the method developed.
