Application of multi-criteria decision making methods for selection of ship internal layout design from a Pareto optimal set

Abstract

Multi-criteria decision making methods are applied to select the final design from the Pareto front obtained in multi-objective optimization problems in a ship design problem. The focus is on the selection of the final design of the internal layout of oil tankers. To fulfil this aim, some of the widely used methods of multi-criteria decision making are applied and the final selected internal layout dimensions are discussed in a comparative study for a shuttle tanker. Whereas the final selected design by the multi-criteria decision making methods is significantly dependent on the specified weight for each criterion, the weights are defined by two methods. First, the objective weights are defined by Shannon entropy technique, next the Monte Carlo simulation is used to compare the ranked solutions by random subjective weights. The selected design by the applied methods of multi-criteria decision making is discussed for both weight assignment approaches.
