An Optimisation-Based Space Allocation Routine for the Generation of Feasible Ship Designs

Abstract A proof-of-concept of an optimisation-based space allocation approach for the conceptual design of ships is presented. A space allocation routine, integrated with a genetic algorithm, generates a large and diverse set of feasible concept designs, from which the designer can select the designs best reflecting the current set of priorities, without creating designs that cannot exist, e.g. by being insufficiently stable. As a result, the human designer is provided with flexibility at a high level of detail and can therefore focus on resolving difficult compromise decisions. A test case dealing with the design of an offshore patrol vessel shows the possibilities of the new approach.
