Abstract. This paper presents a heuristic building block for wind farm layout optimization algorithms. For each pair of wake-interacting turbines, vector is defined. Its magnitude proportional to the speed deficit waked turbine due waking turbine. direction chosen from inter-turbine, downwind, or crosswind directions. These vectors can be combined all turbines and averaged over resource obtain ...

Abstract Discontinuity layout optimization (DLO) is a powerful numerical limit analysis technique that can be used to identify the collapse load and associated failure mechanism of solid or structure. The method successfully automates traditional ‘upper bound’ plasticity, with applications including metal extrusion problems, where die forces are sought, geotechnical engineering stability founda...

It has been widely demonstrated by many research works that the distribution of a factory can condition its productivity. Because this, in Santiago, Chile, asked authors for advice to evaluate current situation company and what alternatives could be proposed improve performance increasing productivity without incurring too high costs. Among most important requirements requested was study design...

This paper presents a method for determination of optimum positions of single wind turbines within the wind farms installed on arbitrary configured terrains, in order to achieve their maximum production effectiveness. This method is based on use of the genetic algorithm as optimization technique. The wind turbine aerodynamic calculation is unsteady, based on the blade modeled as a vortex lattic...

In many application areas an optimal visualization of a complex graph depends on the specific task to be accomplished by the user. Therefore a means of locally customizable layouts is required to focus on different problem aspects. We propose a concept of user-driven hierarchization and layout optimization in the context of IBM zSeries I/O configurations. We combine the concepts of glyphs, loca...

The sewer layout in flat areas significantly influences the construction and operational costs as well as reliability of the network performance. To find an optimum design of sewer networks for flat areas, this study presents a multi-objective optimization problem with the objective functions of 1- the cost and 2- the reliability. The reliability criterion is defined as the effect of a clogging...

In this paper, application of a multi-objective evolutionary algorithms is explored for solving multi-objective placement, packing, or layout problems. Placement problems are optimization problems concerned with finding an optimal arrangement of multiple items in a large containing region while satisfying prescribed requirements and constraints. This study is applied to the configuration design...
