Sažetak
Paper presents the methodology of decision-making for ship/structure multi-criteria design problems. Following points are discussed: Decision support problem identification and formulation. Formulation of the ship or ship structure mathematical module in the decision-making system. Design mapping vs. evaluation mapping. Multi-attribute versus multi-objective approaches/techniques for decision making. Problem manipulations and solution strategies. Concept of non-dominance for filtering the efficient solutions (Pareto frontier). Inter and intra attribute preferences. Attribute normalisation using fuzzy functions. Determination of consistent relative importance of attributes. Designer's heuristic preferences regarding multiple attributes and selection among efficient solutions using Lp-norms. Interactive selection of preferred design with selection of the attribute weights, distance norms, targets, membership grade, etc. Sensitivity analysis. Robustness. Visualisation Applications to the ship structures in practical design environment developed for the efficient design process
