Title: OPTIMISATION TECHNIQUES IN SHIP CONCEPT DESIGN
Abstract: The paper describes an integrated computational approach to ship concept design using optimisation techniques. Although normally heavily automated, the approach used also allows for the designer's naval arcitectural knowledge and creativity to direct the design process. The method described incorporates accepted naval architectural tools, a sophisticated database handler and several optimisation procedures. It is based on a modular construction and this provides the designer with the ability to modify or include a variety of analytical methods and data to suit the problem in hand. It also allows the designer to select appropriate goals for optimisation and to prescribe limiting constraints. Using such a system the design process follows its normal course commencing from a small set of key parameters and proceeds towards a complete hull-form definition consisting of weight, space, offset data, etc. The advantages of employing optimisation techniques in this process are discussed and contrasted with more traditional CAD methods where all design decisions are retained by the user. The possible uses of expert systems in this role are also briefly addressed. The philosophy and structure of the proposed approach are illustrated by its application to the preliminary design of a frigate hull. The example studied uses dual optimisations. Additionally, several different optimisation procedures are outlined, and their merits, failures, suitability etc. are discussed in the context of ship design.
