Multi-Attribute Concept Design Model of Patrol, Rescue and Antiterrorist Craft

Multi-attribute design model of the patrol, search and rescue and/or antiterrorist craft (PASARAT) is developed. The aim of the multi-attribute design procedure is to find parameters and attributes of the feasible and Pareto-optimal vessels subject to constraints. The attributes considered are speed, allowable service time in prevailing sea conditions, acquisition cost of the vessel etc. Parameters of the model are: principal dimensions, coefficients and displacement of the vessel. Optimal propulsion engines are selected from the input engine catalogue, while fixed pitch propellers, surface piercing propellers and water jets are described via parametric regression models. Pareto-optimal designs found by applying the principle of non-dominance to the normalized attributes are sorted according to the Chebyshev metric. Multiple graphical presentations of the multi-dimensional design space are provided in order to gain much better insight into the performances of optimal vessels than it is possible by the mono-criteria approach.
