Shape Optimization of Trawl-doors Using Variable-fidelity Models and Space Mapping

Design Space Reduction in Optimization Using Generative Topographic Mapping

1. Abstract Dimension reduction in design optimization is an extensively researched area. The need arises in design problems dealing with very high dimensions, which increase the computational burden of the design process because the sample space required for the design search varies exponentially with the dimensions. This work describes the application of a latent variable method called Genera...

Design Space Reduction for Multi-objective Optimization and Robust Design Optimization Problems

Modern engineering design often involves computation-intensive simulation processes and multiple objectives. Engineers prefer an efficient optimization method that can provide them insights into the problem, yield multiple good or optimal design solutions, and assist decision-making. This work proposed a rough-set based method that can systematically identify regions (or subspaces) from the ori...

Variable Fidelity Optimization Using a Kriging Based Scaling Function

Solving design problems that rely on very complex and computationally expensive calculations using standard optimization methods may not be feasible given design cycle time constraints. Variable fidelity methods address this issue by using lower fidelity models and a scaling function to approximate the higher fidelity models in a provably convergent framework. In the past, scaling functions hav...

Vibration and Noise Reduction Optimization Design of Mine Chute with Foam Aluminum Laminated Structure

The mining chute is an important equipment in the process of coal transportation and coal screening preparation. During the working process, the mining chute will generate a lot of vibration and noise because of constantly friction and impact of gangue and coal blocks. In order to reduce the vibration and noise during the operation of the chute, a new type of foam aluminum laminated structure i...
