“…Index space, see LS INGRID (1998), enables a very comprehensive design description; see Andric and Zanic (2010). It is a compact structural description particularly related to the support of different descriptors and criteria on the ship's 3D grid (spacing) level by, e.g., frame number, deck number etc.…”

The paper presents the principal steps in the definition of a practical design model for multi-criteria synthesis of complex thin-walled ship structures in concept and preliminary design. It elaborates the general requirements on the design procedure, balanced and applicable combinations of design models and a practical example of the basic analysis models/IT modules within the MAESTRO/OCTOPUS design support system. System identification from the multi-stakeholder perspectives of owner and society, and the formulation and solution to the dimensionally large-scale structural designs are presented as a step towards the practical implementation of multi-criteria decision-making in ship design practice since only a joint effort could lead to the satisfaction of all stakeholders in today's challenging ship-building industry. The practical structural design procedure/methodology, capable of embedding multiple design quality criteria, is demonstrated using a benchmark case study on the innovative RoPax ship.

“…The structural design is based on the generic ship 3D FEM models, of the CDP fidelity level, e.g. using gross elements/surrogates (see Andric and Zanic 2010) and analytically defined adequacy criteria. Loads and adequacy criteria are based on the BV Classification Society Rules.…”

“…This method is far simpler than the requirements for the detailed meshes needed in Nastran or Sesam software. Furthermore, based on the block of macro elements and gross-elements (Andric and Zanic, 2010), for preliminary design of multi-deck ships, a kind of generic ship model has been proposed which is good at fast investigation of ordinary scantling/material optimization as well as different structural topological/geometrical concepts. Presently, the use of statistical techniques to build approximations or meta models of expensive computer analysis codes pervades much of today's engineering design, such as the response surface methodology (RSM), Taylor series, Kriging Model (Martin and Simpson, 2005; and the powerful ANN method (Desai et al, 2008).…”

A new multi-level analysis method of introducing the super-element modeling method, derived from the multi-level analysis method first proposed by O. F. Hughes, has been proposed in this paper to solve the problem of high time cost in adopting a rational-based optimal design method for ship structural design. Furthermore, the method was verified by its effective application in optimization of the mid-ship section of a container ship. A full 3-D FEM model of a ship, suffering static and quasi-static loads, was used as the analyzing object for evaluating the structural performance of the mid-ship module, including static strength and buckling performance. Research results reveal that this new method could substantially reduce the computational cost of the rational-based optimization problem without decreasing its accuracy, which increases the feasibility and economic efficiency of using a rational-based optimal design method in ship structural design.
