2.2. Characteristics of Vessel Design Some significant characteristics of the vessel design process can be identified as follows: • Multidisciplinary nature of design - The problems associated with the design are multidisciplinary, dealing with different aspects such as structure, form, stability, mission requirements, hydrodynamics etc. • Iteration - In any design activity there must be assessment of performance in relation to the purpose and objectives of the design. A measure of the error and recognition of required corrections of the proposed design are required to reach the final design result. • Multiplicity of solutions - There can be many solutions to a given design problem, all of which may achieve the objectives, and may be technically and economically feasible. • Multiplicity of objectives - The criteria for identifying the best design cannot always be reduced to a single type of measure and many different objectives with different measures may be used in the specification. Furthermore, the assumed measures of merit may not be equally important to the final design. • Boundedness - Creative endeavor cannot be allowed to develop indefinitely in any direction. If it is to be feasible it must be contained within those areas, which are judged to bring value, and provide solutions, which are permissible, sensible and susceptible to manipulation. Boundaries, or constraints, need therefore to be prescribed within which the important parameters of the problem may be manipulated to improve the design. Within the boundaries, the effect of the parameter changes upon the fulfillment of the objective should be measurable in terms of value or benefit. • Approximation - The process of creating and evaluating a model does not always follow well-formalized rules with exact theoretical bases. Very often relationships of an empirical nature are used. Furthermore, in any particular design process, the sequence of using relationships and 10PDF Image | FIBER REINFORCED PLASTIC BOAT IN SERIAL PRODUCTION
