Fuzzy Optimal General Arrangements in Naval Surface Ship Design

摘要

A new approach to generating, evaluating, and optimizing general arrangements of naval surface ships is presented in this paper. Beginning from a known hull form with fixed main structural members, the user edits the continuous longitudinal passages and the default list of relevant ship spaces with associated constraints for location, adjacency, and shape. Spaces are allocated to discrete regions of the ship called Zone-decks. Operating one Zone-deck at a time, the topology and geometry are solved iteratively. The geometry step returns all of the spaces' and accesses' bulkhead locations on an orthogonal grid and a cost function evaluation to the genetic algorithm optimization on topology. The proposed algorithm returns an optimal arrangement as defined by the user specified goals and constraints and by utilization of the available area.
