A computational intelligence decision-support environment for architectural and building design: CIDEA

Environmentally friendly and comfortable buildings are a much sought after goal in today's architectural practice. In order to improve energy consumption of buildings without sacrificing indoor comfort, careful consideration of design decisions is needed. Simulation tools provide a solution to one aspect arising from this need, namely the...

Engineering an Optimal Wind Farm

The project covers creation of a framework for optimisation of wind farm layouts. The optimisation is done with an objective of maximising the Net Present Value of the farm. With that aim, both power production and the fatigue driven component degradation are considered. The work is split in two main parts. First, in order to circumvent the use...

Trajectory driven multidisciplinary design optimization of a sub-orbital spaceplane using non-stationary Gaussian process

This paper presents the multidisciplinary optimization of an aircraft carried sub-orbital spaceplane. The optimization process focused on three disciplines: the aerodynamics, the structure and the trajectory. The optimization of the spaceplane geometry was coupled with the optimization of its trajectory. The structural weight was estimated using...

Stochastic Surrogates for Measurements and Computer Models of Fluids

Both measurements and computer simulations of fluids introduce a prediction problem. A Particle Image Velocimetry (PIV) measurement of a flow field results in a discrete grid of velocity vectors, from which we aim to predict the velocity field or related quantities. In Computational Fluid Dynamics (CFD), the output of the computer code depends...

Optimization of Urban Wastewater Systems using Model Based Design and Control

In this research a considerable amount of scientific evidence had been collected which leads to the conclusion that the urban wastewater components should be designed as one integrated system, if the protection of the receiving waters is to be achieved cost-effectively. Even more, there is a need to optimize the design and operation of the...

Manifold mapping optimization with of without true gradients

This paper deals with the Space Mapping optimization algorithms in general and with the Manifold Mapping technique in particular. The idea of such algorithms is to optimize a model with a minimum number of each objective function evaluations using a less accurate but faster model. In this optimization procedure, fine and coarse models interact...

A surrogate based multistage-multilevel optimization procedure for multidisciplinary design optimization

Optimization procedure is one of the key techniques to address the computational and organizational complexities of multidisciplinary design optimization (MDO). Motivated by the idea of synthetically exploiting the advantage of multiple existing optimization procedures and meanwhile complying with the general process of satellite system design...
