Title:
Intelligent Data-Driven Systems for Digital Design in Maritime Industry
Abstract:
Robust Sensitivity Analysis (SA) is a prerequisite for efficient shape optimisation. A major challenge SA has to handle is related to the fact that a parameter can be sensitive in certain local areas of the design space but become insensitive in others. In this connection, we introduce the concept of intra-sensitivity to identify parameters whose perturbation has a major impact on the sensitivity index of the remaining parameters. To expedite SA in the context of shape optimisation of free-form shapes, we construct a Shape-Signature-Vector
(SSV) and propose to use it as a substitute for physics. SSV is composed of shapes’ integral properties, in our case geometric moments and their invariants of varying order, and is used as quantity-of-interest (QoI) for prior estimation of parametric sensitivities. Finally, we will introduce ShipHullGAN, a generic parametric modeller built using deep convolutional generative adversarial networks (GANs) for the versatile representation and generation of ship hulls. At a high level, the new model intends to address the current conservatism in the parametric ship design paradigm, where parametric modellers can only handle a particular ship type.
