Abstract In this paper, multi-objective optimization (MOO) of Al2O3-water nanofluid flow in microchannel heat sinks (MCHS) with triangular ribs is performed using Computational Fluid Dynamics (CFD) techniques and Non-dominated Sorting Genetic Algorithms (NSGA II). At first, nanofluid flow is solved numerically in various MCHS with triangular ribs using CFD techniques. Finally, the CFD data will...

In spite of being introduced over twenty-five years ago, Fonseca and Fleming’s attainment surfaces have not been widely used. This article investigates some the shortcomings that may led to lack adoption this performance measure. The quantitative measure based on surfaces, by Knowles Corne, is analyzed. analysis shows results obtained Corne approach are influenced (biased) shape surface. Improv...

In recent years, wind farm layout optimization (WFLO) has been extendedly developed to address the minimization of turbine wake effects in a farm. Considering that increasing degrees freedom decision space can lead more efficient solutions an problem, this work WFLO problem grants total area shape is addressed for first time. We apply multi-objective with power output (PO) and electricity cable...

: nowadays, organizations are faced with a multitude of project and investment opportunities. despite the importance of various criteria, complexity of multi-objective models and weakness of optimization algorithms often compelled manager to limit the selection criteria or only suffice to financial objects. in this paper, it is endeavored to extend selection criteria by using an efficient optim...
