Abstract:A method and an algorithm are proposed for solution of multicriterion problems of structural and parametric optimization of nonhomogeneous anisotropic constructive elements under the condition of the choice of an acceptable hierarchical structure of a complex construction, an appropriate distribution of requirements on each functional constructive element of each hierarchical level, and a reasonable trade-off between inconsistent requirements on the strength, reliability, and adaptability to manufacture and technical and economic efficiency of the construction, taking into account the risk degree and risk level of non-nominal situations. The efficiency of the method proposed is illustrated by an example of choice of an acceptable structure of a complex system, namely, a wind turbine.
Keywords: complex construction; hierarchical structure; multicriterion problem; nonhomogeneous anisotropic constructive element; structural and parametric optimization; structure of a wind turbine; trade-offs between requirements and efficiency
