Multiattribute Decision Making Methodology for Handymax tanker Design in the Concept Design Phase - A Case Study
An improved methodology of decision making for ship concept design, with the related design procedures and mathematical models, is presented. The mathematical model includes optimization of the main newbuilding characteristics as well as the optimization of its commercial effects. The Multiattribute decision making method is applied and the ship design analysis model is inbuilt into the decision making shell DeMak. Each attribute is defined by the membership grade function based on fuzzy set theory. The consistent relative significance of attributes is obtained as an eigenvector of the subjective decision making matrix (AHP). Inadequate information about the configuration of the feasible designs´ subspace is overcome by sequential adaptive generation of design points in the feasible region (via e.g. adaptive MC method, MOPSO or MOGA). The concept of nondominated designs is used for filtering Pareto solutions. In practical applications to the general design of cargo ships, the developed design procedure and the associated mathematical models for the multi-attribute design synthesis have resulted in considerable improvements of the vessel’s quality measures. It makes this design approach superior to traditional ship design and ranks it among promising approaches for those ship types in the concept design phase. The application of the method is presented for the concept design of Handymax Product Tanker.
