Sažetak
Multi-criteria design of complex engineering systems is methodologically and computationally demanding and time consuming process. Optimization algorithms, problem decomposition, surrogate metamodeling and methods for decision support are synthesis methods that are usually employed to solve the design problem. The design of complex thin-walled structure (e.g. ship and/or aircraft) falls within the category of large scale problems characterized by several design objectives, hundreds of design variables and tens of thousands of design constraints. The objective of the research presented in this paper is to improve the design process of complex thin-walled ship structures through an application of surrogate modeling (Response Surfaces, Kriging, Radial Basis Functions) for this type of a problem. Methods considered are integrated into interactive computing environment for multi-criteria design in order to enable effective and efficient interaction between designer and design problem within given design timeframe. Applicability of the proposed approach is extensively tested on a simple barge example, and finally applied on a design of a realistic modern multi-deck ship.
