It can be applied to many disciplines in this field, namely efficiency improvement of  engine blades, noise reduction of engine nozzles, or reduction of the fuel consumption of aircraft. Optimization for general purposes is also of increasing  interest in many other fields.    traditionally, optimization procedures were based on deterministic methodologies as in hamalainen et al (2000), where the optimal working point was  fixed. However, not considering what happens in the vicinity of the defined working conditions can produce problems. That is, in many cases, if the real  working point differs from the original, even a little distance, efficiency is reduced considerably as pointed out in huyse and lewis (2001).    non deterministic methodologies have been applied to many fields (papadrakakis, lagaros and tsompanakis, 1998; plevris, lagaros and  papadrakakis, 2005). One of the most extended non-deterministic methodologies is the stochastic analysis. The  time consuming calculations required  on computational fluid dynamics (cfd) has avoided an extensive application of the stochastic analysis to shape optimization. Stochastic analysis was  firstly developed in structural mechanics, several years ago. Uncertainty quantification and variability studies can help to deal with intrinsic errors of the  processes or methods. The result is no longer a point, but a range of values that defines the area where, in average, optimal  output values are  obtained. The optimal value could be worse than other optima, but considering its vicinity, it is clearly the most robust regarding input variability.    uncertainty quantification is a topic of interest from the last few years. It provides several techniques to evaluate uncertainty input parameters and their  effects on the outcomes. This work presents a methodology to integrate evolutionary algorithms and stochastic analysis, in order to deal with  uncertainty and to obtain robust solutions.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Contribution to the definition of non deterministic robust optimization in aeronautics accounting with variable uncertainties<\/strong>\u00ab<\/h3>\n<ul>\n<li><strong>T\u00edtulo de la tesis:<\/strong>\u00a0 Contribution to the definition of non deterministic robust optimization in aeronautics accounting with variable uncertainties <\/li>\n<li><strong>Autor:<\/strong>\u00a0 Jordi Pons Prats <\/li>\n<li><strong>Universidad:<\/strong>\u00a0 Polit\u00e9cnica de catalunya<\/li>\n<li><strong>Fecha de lectura de la tesis:<\/strong>\u00a0 02\/03\/2011<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3>Direcci\u00f3n y tribunal<\/h3>\n<ul>\n<li><strong>Director de la tesis<\/strong>\n<ul>\n<li>Gabriel Bugeda Castelltort<\/li>\n<\/ul>\n<\/li>\n<li><strong>Tribunal<\/strong>\n<ul>\n<li>Presidente del tribunal: eugenio O\u00f1ate ib\u00e1\u00f1ez de navarra <\/li>\n<li>Juan  Jos\u00e9 R\u00f3denas Garc\u00eda (vocal)<\/li>\n<li>valentino Pediroda (vocal)<\/li>\n<li>adel Abbas bayoumi (vocal)<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tesis doctoral de Jordi Pons Prats Shape optimization is a largely studied problem in aeronautics.
