The Application of Fuzzy Modeling and PSO in Spaces Allocation of Naval Ship

Abstract

A semi-automated general arrangement technique of naval ship is discussed, it approached by a series of two essentially two-dimensional problems: the allocation of spaces to Zone-decks (one deck within one vertical zone), after that, implement the detailed arrangement of spaces to each Zone-deck. In this context, fuzzy modeling is introduced for evaluating environmental loadings (noise, vibration and ship motion) and Naval Equipment Standards, and then these measures are translated to fuzzy utility values which express the satisfaction location of each group spaces. The fuzzy location preference values are combined with Zone-deck utilization utility to establish the objective function using fuzzy product inference. Lastly, the particle swarm optimization (PSO) is performed on the objective function to acquire the allocation plan of spaces in each Zone-deck.
