Sažetak
The latest development of the multi-attribute concept design model of the fishing vessel is presented. A wide data base of fishing vessels made it possible to introduce reliable parameter relations in the design model. The model is aimed primarily at the Adriatic type of fishing vessels with the length of up to about 30 m. Steel, aluminium, timber or glass composites are possible choices for the hull structural material. Weight estimating is based on plating areas and selected building material. A ship cost estimating procedure is developed. Complete new regression analysis of the UBC model series was performed in order to enable resistance prediction of the low length to beam ratio hulls, since large beam is a trend in modern fishing vessels. Freeboard at the bow is analysed and appropriate relations found. Statistical relations of design parameters were developed in order to constraint the model to realistic proportions. The model is included in the multi-attribute design procedure which explores design space and produces Pareto-optimal (non-dominated) designs in multi-attribute environment. Within these non-dominated designs final design is selected by searching for minimal distance to the ideal design using fuzzy concept to describe aspiration level, subjective decision making and Chebyshev metric in the decision space.
