global meta-model for system level multidisciplinary design optimization

this paper presents an efficient global meta-model building technique for solving high fidelity multidisciplinary design optimization (mdo) problems. the main difficulties associated with mdo are often characterized by interdisciplinary couplings, high computational cost of an analysis in individual disciplines and a large number of design variables and constraints. these issues result in very ...

Multidisciplinary Design Optimization

Multidisciplinary design optimization (MDO) is a field of engineering that focuses on use of numerical optimization to perform the design of systems that involve a number of disciplines or subsystems. The main motivation for using MDO is that the best design of a multidisciplinary system can only be found when the interactions between the system's disciplines are fully considered. Considering t...

Parallel and Distributed Methods for Nonconvex Optimization-Part I: Theory

In this two-part paper, we propose a general algorithmic framework for the minimization of a nonconvex smooth function subject to nonconvex smooth constraints. The algorithm solves a sequence of (separable) strongly convex problems and mantains feasibility at each iteration. Convergence to a stationary solution of the original nonconvex optimization is established. Our framework is very general...

Formation of Poly(vinylidenefluoride) Nanofibers: Part I Optimization by Using of Central Composite Design

Poly(vinylidene fluoride) (PVDF) nanofibers were prepared via electrospinning process. Several different factors influence on this process and application of experimental design for its optimization is of great importance. The central composite design (CCD) was used for planning and optimizing of the experiments and also, the analysis of variance (ANOVA) was employed for the statistical va...
