“…De acuerdo a Erbatur y Hasancebi (2000), la operación de cruzamiento representa 90% de la población creada y se aplica en los mejores individuos para crear dos descendientes de dos padres. Algunas aplicaciones y descripciones de diversos cruzamientos se pueden encontrar en Rajeev y Krishnamoorthy (1997), Erbatur y Hasancebi (2000), Ali et al (2003), Dominik (2006) y Haupt (2008. Las técnicas de cruzamiento se aplican en representaciones con núme-ros binarios o reales y sus aplicaciones en diseños estructurales incluyen soluciones en espacios continuos (Rajeev y Krishnamoorthy, 1997).…”

ResumenEn este trabajo se propone un algoritmo genético con "cruzamiento natural" y se aplica sobre una representación continua-discreta con el fin de optimizar armaduras. El objetivo es disminuir el peso restringiendo los desplazamientos de los nodos y limitando los tipos de perfiles estructurales a usar. Las soluciones se combinan con dos tipos de cruzamientos en la misma representación, que permiten explorar de una manera efectiva el espacio de búsqueda. Los resultados se validan comparando los encontrados en este trabajo contra los de la literatura, para el caso del diseño de la armadura de un puente de 70 m de claro. Se obtienen soluciones más ligeras y con diferente topología. Adicionalmente se propone un caso de estudio, el diseño de la techumbre de un invernadero, que después se construye a escala real y se somete a cargas para verificar su resistencia. Descriptores• asimetría • armadura de gran claro • invernadero

“…The application of different optimization technique to structural problem has attracted the interest of many researchers. For example Ray Optimization 6 , artificial bee colony algorithm 16 , Particle Swarm Optimization 6,7,12,14,15,17 2007)). Fuzzy as well as intuitionistic fuzzy optimization in case of structural engineering not only helps the engineers in their design and analysis of systems but also leads to significant advances and new discoveries in fuzzy optimization theory and technique.…”

In this paper, we have introduced a intuitionistic fuzzy mathematical programming with intuitionistic fuzzy number as co-efficient of objectives. Real world engineering problems are usually designed with imprecise parameter by the presence of many conflicting objectives. In this paper we develop an approach to solve multi-objective structural design using probabilistic operator. Here total integral values of triangular intuitionistic fuzzy number,and it has been used for imprecise applied load and material density in the test problem. In this paper we have considered a multi objective structural optimization model with weight and deflection as objectives and stress as constraint function. Here design variables are considered as cross sectional area of bars. This classical truss design example is presented here in to demonstrate the significance of our proposed optimization approach. Numerical example is given here to illustrate this structural model through this approximation method.
